    Hello All! Despite everything I've been told and read I couldn't resist....I have always loved Esprits! I'm not shy of picking up a socket and have built/modified/restored my fair share of cars in the past, so when this car came up I think the fact that it was modified, and that it has pretty high mileage under its wheels (78k) it put most people off, but I was intrigued. It is one of the first "facelift" V8s (built in '97, registered in '98) and is Nautilus Blue. I bought it from a lovely 76 year old Lotus nut (also has other Lotuses) in Cheshire and who had had it for a few years and had looked after it pretty well. Before he bought it the previous owner had modified it extensively with forged pistons, new liners, chargecooler, hybrid turbos, ARP head bolts, Forge waste gates new fuel tanks, Quaife LSD, Alcon 6 pot front and AP 4 pot rear brakes, OZ Novas, round rear lights and centre exit, as you can see its has been pretty heavily worked over. I had PNM look it over, and although there are a couple of (usual) things, it got the nod from Pete so I decided to give it a shot. Its with PNM right now having some of the jobs done (gearbox oil leak, new engine and g'box mounts and make the heater work), so I don't actually have the car yet and hope to pick it up next weekend. So, here's the rub.....and where I need the help of the forum if possible. At the moment the boost comes in with a bang at 4,000rpm. The guy I bought it off said that it used to be much more progressive, but its been stood outside (under a lean to) for the last couple of years and I think the lack of use has affected something. PNM are going to have a quick look to see if anything obvious is wrong, but if anyone has any ideas what may be causing this I would massively appreciate your advice. Boost control leak, sticking actuators? Also, if anyone knows anything about this car, or who modified it (or had it done) please let me know. Apparently it was a guy called Roy, who lives near Doncaster - so if that's you, please drop me a PM - I'd LOVE to talk through the history of the car with you and get it back to full fighting fitness. There isn't a lot of documentation with the car, and no invoices from the modifications so I'm trying to work back. Before you all agree too quickly with my self diagnosis of automotive madness, I should add that the car has run pretty well faultlessly for the last few years since it was modified (according to Barrie who I bought it off), and the boost problem is relatively recent, so it seems that the work was done well.... So any info, ideas and help will be gratefully received. Here's a pic (from before I bought it)....

    Today I collected my new Lotus Exige Sport 350 in Vivid Green in Mendig from KomoTec - unsuprising I'am still overwhelmed and just totally happy Beside the cool colour above all I'am exited about the AIM KomoTec MXS Strada Display - the quality of craftmanship conducted by KomoTec here is outstanding - regard how their control buttons for the MXS are intergated in the cover of the steering wheel! Awesome!

    Superdudes! And beardy types. I am about to return my Esprit to the roads of Britain and thought I would give you a bit of a heads up, seeing as you're into this type of thing. But, please note; a, this is not a restoration, and, b, I have not done any of the work myself (thankfully for all concerned, including the car). Background - two and a half years ago I decided to buy an S1 and modify it (on the basis that the car in original form could not be considered a daily driver). But, it became clear that to modify an S1 would be a bit like touching up the Mona Lisa, so I decided not to take on the sandal and pipe brigade and settled for an S2. Now, at the time, there were actually more S1's (one) on the market than S2's (none)! The market has changed muchly since then (there are now more S2's (and Sport 350's, weirdly) than bearded middle aged men to drive them!). Luckily, Bibs rode his keyboard to the rescue and I ended up buying a partially restored S2 from Bell and Colvill, which happened to laying low at their super secret workshop in Bristol; namely Tomorrow's Classics. And, there it has remained for the past two and a half years, being stripped and poked and hammered and bolted. And sworn at. The intent - To create a 'G' Esprit that can be used everyday, with absolute priority going to safety and reliability, without fundamentally altering the look. The work - the list of work completed on the car is, not unusually, quite extensive. So, please take all the elements of a standard 'body off' 'nut-and-bolt' restoration as read, including upgrading where practicable. In sum, the major work has included: Mechanical: Refurbished, powder-coated chassis Refurbished and upgraded engine to high compression 2.2 litre fuel injection system and stainless steel exhaust Upgraded suspension system, lowered and adjusted for larger wheels Upgraded brakes Upgraded gearbox and clutch with new gear linkages, lightweight flywheel, clutchplate etc Refurbished steering rack Upgraded cooling system with alloy radiator, triple fans, water pump, stainless steel pipes etc Added oil cooling system Replaced HV unit with integrated, compact HV+AC system (compressor, condenser, evaporator etc) Replaced windscreen wiper motor, arm and blade with uprated version Replaced fuel tanks with baffled versions, increase tank-to-tank flow, fuel pump etc Interior: Re-sighted/replaced 2 air vents with 2 circular vents (to side window positions) Added control panel to binnacle for HV+AC Added sound proofing / insulation (dynamat and dynaliner and lots of it) Replaced seat belts (change belt colour to tan) Replaced interior marcasite trim with brown alcantara Added S1 style central chrome ashtray (central arm rest 'de-ribbed') Painted new binnacle facia satin black, upgraded gauges, replaced switchgear and warning lights Bodywork: Replaced fuel filler caps with locking versions (S3 style) and painted body colour Removed original aerial and painted hole in bodywork Replaced wheels with Woolfrace styled highly polished, wider replica 17” special build wheels Painted engine cover and hatch gold Replaced front and rear screens with 'special build' versions Electrical: Upgraded electrical system with high capacity battery, alternator and wiring etc Added reversing camera and 2 reversing sensors (flush into the rear bumper) Replaced speakers, relocated to rear bulkhead and added tweeters to A pillars Replaced stereo with double din Apple Car Play mechless system (Sony XAV-AX100), including phone preparation, integrated radio aerial and USB power socket to glove box Added central locking / remote boot release / alarm and immobiliser Replaced all bulbs everywhere with LEDs Added LED DRLs to front air intake (in front of grille) Added side indicators Added high rear LED brake light Replaced headlights with bi-xenon There's still a little of this list left to be completed, but the car is on the home straight, with just the electrical installation, ECU programming and road testing to be completed. The workers - as I have said, not me. Tomorrow's Classics, based just north of Bristol have completed the work (both before and after change of ownership), and I can not praise them highly enough. Nick, Rory, Steve, James (their leccie superdude) and Keith (on upholstery) have done a superb job and come highly recommended. But don't take my word for it, Bell and Colvill use them for their restorations and currently there are (I think) seven Esprits in the shop being worked on. Can't praise Nick and his team enough. They've been fantastic to work with on this project. And it's not been quick, or easy (apparently fitting air con to a non air con Esprit is a bit of a job - who knew?). The engine, incidentally, is an 'everything on the menu, please' LotusBits rebuild. You name it, LotusBits threw it in. The money - I'm all at sea about whether to reveal the cost, suffice to say, it's 6 figures and a whole lot more than any S2 is worth, or is likely to be worth anytime soon. But, that isn't the issue for me - it's my car, for me. So, in five weeks time (as I am away until early August), the car will be ready for the road, and I am superly turbo excited. I attach a montage of pictures from throughout the build (because pictures, right?) and would appreciate your thoughts (noting that it's too late to change anything, and I wouldn't anyway). Awe. Some.

    Well, following soldave's post about this, we took the plunge and completed the rally yesterday. For those who dont know about this, the Fireball Rally is an organisation that arrange various types of motoring holidays in Europe We signed up to James Bond's Switzerland one that is an endurance event planning to visit 8 countries in 4 days, totalling 1800 miles!! Many people buy cars specifically for the event, usually under £900 but we chose to take the Esprit. Now, my Esprit has never let me down ever, but the closer the rally got, the more nervous I became and sure that I was about to make a monumental mistake. However, with my son about to start at University, it also seemed likely to be a rare opportunity to bond (over some Bond) that may not arise again for some time. He got the grades, freshers dont start till next week and so we were on!! Planning is everything they say and this is no different. I went over the car with a reasonably fine tooth comb, finding a few minor faults and the need to replace all 4 tyres. The week before we were to go, I also managed to slice my index finger to the bone trying to remove some sealant on the rear quarter window. It really needed stitches but we used some superglue in the end (no different to proper skin glue but not really recommended!) Other things needed - check with insurance company that they will cover ALL countries to be visited. Adrian Flux were great about this and confirmed in writing but others had difficulty. The last minute covers are expensive so better to do ASAP. Add to that European breakdown for a classic car - the best cover will get your car back, provide a courtesy and cover all reasonable costs, along with providing some valuable peace of mind. Satnav provided by Google maps was great, as the destinations were given as global coordinates (mountains dont have postcodes) and worked very well. As we were camping, packing the esprit was not easy and infact as you will read later, created one of the worst problems we encountered on the trip!! This is with no clothes etc etc. The sleeping bags actually went in the front compartment in the and and our coats went on the little shelves but you can see the space issue. As we had just replaced all 4 tyres, we ditched the spare (gulp) to get more space and took a puncture repair kit, tyreweld foam tyre filling thing and crossed our fingers!! The Mustang that came got a flat on the first day but a French garage repaired it for free. Despite Brexit, they dont hate ALL of us!! The other fly that hit the ointment was reports of 50cm of snow on the passes the weekend before we were to go. Hadnt really expected that so, after a moment of panic, bought some snow socks. Didnt need them in the end so I now have a brand new set of AutoSocks to fit an Esprit should anyone want a bargain!!! Thursday 12th Sept and we are ready to go!! Ferry crossing to Calais at 0640 the next morning - smooth and event free. Then a 500mile run for the sun towards Switzerland, through France, first stopping at the Reims-Gueux abandoned GP circuit The main road just runs though the old start/finish straight/pit lane and is a must visit if you are anywhere nearby. The next 4 days saw us visit Switzerland, Italy, Austria, Liechtenstein, Germany, Luxembourg, Belgium. Amazing. Here are some of the highlights. A thing near Verdun Verdun Ossuary Piz Gloria restaurant at the top of the Schilthorn - On Her Majesty's Secret Service Grimsel & Furka pass (Goldfinger) Goldeneye Dam Stelvio pass Castle Neuschwanstein (get the Bond link???) I could go on and on but hopefully have illustrated the Lotus in places you might not expect it!!! Well, it performed very well indeed. Never broke down. Never failed to start. Was really quite comfortable, the GT as it is. We did encounter some issues though. Traffic jams around Nancy, Bern, M25 etc caused some overheating and coolant loss through expansion. I think this is due to the radiator fans failing to engage above 90 degrees - bad connection somewhere I think. The exhaust also started to blow. We lost a little power as a result but the roar in the tunnels made up for it, particularly when coupled with another roar from the sports exhaust of the MX5 we were in convoy with. The final issue we had was unexpected loss of all headlights whilst in the middle of the Black Forest (aptly named) We think was due to the overloading of luggage in the front compartment pushing against the mess of wiring/relays etc when taking a tight right hander. Not great losing light at this point!! Came back on but was very unnerving each time it occurred. Overall, an incredible trip, great people, amazing sights and putting paid to the notion of Lots Of Trouble etc etc. Everyone we encountered were amazed to see the car and Brexit has not altered attitudes as far as we could tell.

    We do...a small business born by accident and through Esprit ownership and TLF membership, the wife and I both skilled in different trades work together in a little shed at the bottom of the garden most evenings now to produce these carpet sets for most Esprit models. Our latest addition, the allusive Turbo Esprit battery cover which we now make from ABS plastic to replace those cardboard covers that have dissolved over the years.

    Hi Folks, Thought it only polite to say “Hi” and to share a pic or five of my new car bought from Central Lotus in Nottingham. This is my first Lotus and I am thrilled with it. I hope to share my experiences as I rack up the miles with a big road trip planned for early October through France to enjoy the Spanish and Andorran Pyrenees roads. Thanks in anticipation for all of your welcomes and assistance as I get to grips with this great marque. Oh, and how about this, I observed the speedo with 130 miles recorded on the day that the Evija, Type 130 was launched. Cheers all Joe

    Well that was fun ! The Evija is awesome in the flesh - almost conventional supercar from the front until you start looking at the detail, but the completely jaw dropping sculptural holes through the back really show its something well beyond. The "parade" was great fun if predictably shambolic in London traffic with very few of us knowing the roads. This not helped by a late change of route due to roadworks on the Brompton Road. As an ex-biker commuter, I'd have managed OK with new route details....but turn left instead of right at Buckingham Palace and follow the yellow Lotus in front was way short of passing on where to go. As the lights there allowed us out 2 or 3 cars at a time the party inevitably split and we all made our way back in small groups by various circuitous routes the final two arriving a full 40 mins after the first two! What it did do was create incredible interest around the streets of that part of London - particularly when we were all together - with hordes of tourists and regular workers stopping in their tracks and watching us go by - literally lining up along the pavements to get a better look - and there must be thousands of phones now filled with short video clips of yellow Lotus. Others will have better pics that will appear idc no doubt but this was (most of) the fleet that assembled at the start in generation order : Baby Elan Sprint; Elan +2 130/5; Elite; Eclat; S2 Esprit; M100 Elan; V8 Esprit; S1 Elise; Exige RGB; Elise 220 Cup; Evora GT410 Sport; Exige Sport 410. I followed Harry Metcalfe around in his Sprint and he was videoing the whole thing so that will presumably be released on his channel at some point, and Lotus had some photographers on a bike with us and static on the mall so hopefully they got some money shots too. It was such a laugh to see the public's reaction we all did another quick run up to Parliament Square and back before the evening show started. There was what seemed like genuine interest from some of the "big names" (I didn't know any except MJK!), journos and other hangers on as they arrived for their presentation. But of the ones that spoke to me, they shared surprisingly little knowledge of the Lotus back catalogue - given their professional involvement and presumed interest in automobilia. It was a privilege to help enlighten them! Just awesome to be given the chance to have a tiny involvement in such an event - the grin will stay with me for a very long time...

    Technically this was yesterday, but as it was only a few minutes before midnight when I got home from my mission to deepest darkest Lancashire, I'll call it 'today'. Our house has been somewhat empty since the sudden passing of our 'boy' Shadow 2 months back. Not any more!!!! We have welcomed into our family, this big adolescent. She came up for adoption due to her owner's deteriorating health and we couldn't resist giving our old 'girl' Alaska a new (hopefully) best buddy. Say "Hi" to a total live-wire (for that read "complete nutter") - a 19 month old Utonagan called Macha (her name is that of a goddess in ancient Irish mythology to save you some Google time, )

    Been very busy this last month trying to finalise everything before her first car show. However everything has come together and we had a brilliant time at Lytham Green car show this afternoon. (see separate thread). Car looks the dogs... !! Well she does to me anyway. Even my partner, daughter and son in law seem to approve! I would just like to say a huge thank you to everyone on here who has made suggestions, argued, supplied parts etc etc like @Paul Coleman, @Fridge, @jonroberts, @drdoom, @GTK Special thanks must go to @Lotusfab and @Rolls who's threads I have read and re-read over the last year. Just so, so helpful to me. Perhaps I'll should now start a new thread called My Esprit S1 import finally drives about! Of course just because Ive got it driving doesn't mean the hard work isn't going to continue. Watch this space...……………..

    As I said when I introduced myself, thank you all for making everyone welcome; it’s increasingly rare for an online forum! Picked it up yesterday and had a wonderful play today, oil warm, half throttle, up to 3500 - the noise, the sensation, just wow. Cannot wait for the brakes to bed in a little more, but getting there. They said in 1997 if John Major had met everyone personally, he would have won the election, I’m not sure of that, but if everyone who wanted to buy a sports car to drive and not pose, then all Lotus have to do is get them in one for 45 minutes - job done. A couple of questions and observations - Does anyone have all season/winter tyres on the OEM rims? If so, what brand and tyre - struggling to find some at the moment? - it seems like the rubber strip under the front splitter is no longer supplied, is this right, or should I mention it at it’s run in service? - is the supplied radio the most complex bit of IT in the world, or am I getting old? Overall it’s just great. A couple of photos Thanks Stewie

    I’ve wanted a Lotus for a long time, ever since trying to buy an original NA 190 S2 Exige. Finally I can say I’ve joined the club after picking this car up from Charlie last week. Over the moon with it. Im away this week with work, so frustratingly I won’t get to drive it again for another week! Look forward to seeing some of you about. Plus a big thanks to @GFWilliams for putting up with my questions Oh and @alias23 I’ll be in touch

    I have oil pressure! Thanks to Jeremy on here who kindly came over and assisted. Well what was the problem. I tried priming everywhere with a 12 v oil pump, no joy. The best place to prime is the centre of the oil filter screw thread. The gauge even registered pressure when pumping and oil came out of the Turbo feed. RPM 1500, no oil pressure. Yesterday we tried the cooler connections. When I went in this morning the oil level had decreased, so I guess I was correct, the thermostat opened and the oil pressure dropped. When I restarted no pressure???? After this I could only assume the pick up pipe or the pump, the rotors were checked so what else? If the pipe was on wrong I could not have got 75 psi. So I figured it must be the pressure relief valve stuck open in the pump housing. I removed the housing leaving the plenum and everything else intact. Jeremy and me took it off and it didn't take long! . The valve looked suspicious. Jeremy pushed it with a screwdriver and sure enough it was jammed! We cleaned it with brake cleaner and compressed air. Then flooded it with oil and removed all the very small debris. Put it all back together without priming. Just filled the filter half full. A few seconds of cranking and 75 psi. Now consistantly good oil pressure. Happy days! Thanks Jeremy! thanks to all you guys on here who have been helping me with advice and the lads who came over yesterday! Its running very well considering I have rebuilt everything and even the carbs! The adjustment isn't far off and it started very easily. The gearbox is working in first and reverse! Haven't tried the other gears yet. Im having a brake from the car now for a while! Thanks everyone!

    So, I am a long-term admirer of Lotus and the Evora specifically is a car that I have wanted to own for many years. And the time was right in Feb this year as the right car in budget came up (2015 2+2 IPS) I have 1 child (4yrs old) and a wife, therefore the 2+2 is used by the 3 of us and he has plenty of room in the back for him and some his toys / backpack on the 4th seat. (The way the seat is higher in the back with a raised roof in the back, ensures he is sat safely via ISOFIX and he has a great view of the road, plus he loves being near the engine in the back and so close my me at the same time) I still think the Evora is the world’s only mid-engine 2+2? I am mid 30’s and my last few cars have been Automatics and the last was a Jag 3.0d Auto. I like Auto Transmission as my daily commute for work is approx. 100miles, and therefore I do a lot of Motorway miles then slow town traffic at the end of the journey. Therefore, this led me towards the IPS gearbox for the Evora. When I first drove the IPS on a test drive and even since ownership my view is that the IPS gear box is great, it changes gear at the right times, its smooth and Its not too different to my previous 2014 XF gear box for ease of use. BUT, this is a big BUT, when you select the ‘Sport’ mode, the car is AMAZING, its so different to any other car that I have ever driven. It downshifts the gears so quickly and gives you so much speed and excitement. The car really fells like a Super car when in Sport. The quick downshift, the responsiveness isn’t all that’s positive, the noise is great as it opens up the exhaust and also the downshift ‘blips’ are very addictive as the car makes a ‘blip’ sound and revs when downshifting which sounds great and the excitement of that isn’t wearing off! When driving with friends (Who have owned sports cars, including Porsche) are amazed at the quality of the leather, the seats, the dash, the door handles, the way the door closes with a reassuring soft shut, and not a clanky bang, the ride is comfortable. The Sat Nav and the Stereo work really well and a smooth connection via Bluetooth. As I say above, I could drive 100’s miles in one sitting with no negative side effects in comfort. I’m currently on 29.5mpg which I think is amazing (As above, I do a lot of Motorway miles, which helps) To summarise, there was no reason for me to wait all these years to get an Evora. Prices haven’t gone down, it easily can be used as a daily car and I love driving it every time. There’s a lot to read on these forums, and this will help us all make the right purchase, and being patient is key. I wanted to write the above as I’m sure there’s other people like me, in a similar position who are pondering and reading this forum every day multiple times (As I was!!) – Which actually drove me to a point of frustration and a addiction of searching classifieds on every possible website. So to now own a Evora is a welcome ‘relief’ (Not sure if relief is the right word, but I’m sure you know what I mean) I recently parked the car at a restaurant and when leaving followed a few mid aged male friends who I didn’t know, and I heard them look at the car and comment that my car was a nice model of Ferrari. To make the purchase even easier / smooth, I purchased via Silverstone and Aimee who were brilliant. Very supportive in the sales process and providing information and detailing etc. I’m certainly not a lotus expert or a technical / mechanical expert, but If anyone has any questions, please ask me, Ill be more than happy to help. Loving this website and forum and always a joy to read and even today I saw 003a make a post introducing his new great looking Top Gear car and he also shared a Evora transfer sticker, which is great!

    Now at 500 miles (travel and weather has not been kind) and I have found out some very interesting things about my Exige. People are much friendlier to you and want to chat more than in the M4 Fewer idiots want to race than in the M4 - seems they are content watching it from behind Even on half throttle and 4k, the acceleration is great and the accompanying supercharger whine is tremendous Power gets to the road MUCH better than the M4, even in Cup 2's that don't like the cold compared to MPSS Never leave the windscreen wipers on when you get out, or at least close the door before turning the ignition on otherwise a bucket full of water will get in to the cabin Sometimes the mist on the inside of the windscreen arrives for no reason Never open the window before you've got some speed up to clear the standing water from the roof, otherwise, water in the cabin! Finally, there is always a squeak which cannot be identified - Mods - is it worth putting a sticky on squeaks, rattles and bangs somewhere which can help people identify and fix (apologies if I have missed it). I cannot wait until late December when it gets its service and the fun commences Once again, a great forum that engages and is very friendly.

Busying away in the background too and there is progress on the Esprit that'll go live real soon Mark I'll do my best to beat you to the finish Ant, you looked after me for a long old while despite having your own projects demanding time and cash flow, I'm always grateful for that! EDIT; I bloody forgot! [Esprit next!]

    As someone who does this work and understands the dynamic of porting i thought it may be worth me pointing out a few things the lay man is not aware of... Firstly port /manifold alignment is crucial as first move as it disrupts the air flow significantly. See Pic . This is typical on what you see with most 900 series, some worse than others .. However, you first need to ask why would Lotus leave this when they are a performance orientated car maker... The answer could well be that any disruption will assist in the fuel atomization at lower velocities.. What can not be ignored is the performance on cylinder filling (VE) will be reduced and so performance.. So it may mean the fueling system needs refining to match any porting.. We will never know why Lotus didn't address it, but i expect the cost of any refinements would be unacceptable at the time especially when you consider the performance figures were still up there .. So onto porting.. Align joints, yes , but don't barrel the port.. this will give you velocity pulses , disturb and vary the pressures on the back of the inlet valve, the port should be consistent or necking down towards the valve .. Your starting point should be calculations based on projected flow which will be influenced first of all be the Choke you intend to use within the carburetor. There will be laminar layers produced by the surface disruption within the port which can be reduced in line with projected requirements. (porting/polishing.) What you need to consider is that biggest is not best when porting.. For eg. there are some CNC machine ported heads available which look really good , but have far to big a port size for most basic road tune ups.. The reason for this is loss of velocity. For a given flow volume large ports have less velocity smaller higher. What you are looking for is the optimum for your particular engine tune .. So what is that.. Well once again it gets more involved and a secondary starting point is the exhaust system, particularly the manifold.. If you can not get it out you wont put it in. This is a subject on its own, technical points covered in threads on the turbo systems that have been developed. Fortunately there are already LCB systems available for the N/A engine which will give something to work from.. I have not studied them so can not comment, but what is important will be the length of the primary's and the expansion of the collectors. This aspect will have a big effect on the pressure wave inversion within the flow which greatly assist performance when timed correct. Back to the inlet ports .. As you can appreciate max VE is only obtainable through a balance of exhaust and inlets. Assuming the exhaust is optimum then porting size , flow , velocity, can be arrived at . Achieving the best for your engine will require each port to be as close to identical, in shape, volume and surface texture, deviations in this will create anomalies through the tuning process. Volume is easy to check using fluid measuring , same as when doing the combustion chamber, just a lot larger. Shape can be more testing. You will need to be diligent if altering the shape to achieve certain swirl benefits, otherwise following the original form using calipers and care should achieve the desired effect. The pics below shows work in progress from std (left) to porting (right) When you have arrived at the desired finish, it is always best to have it checked out on a flow bench , this will confirm you have the balance across all cylinders. if not then small mods can be done to correct.. The whole idea of porting is to get the max pulsed pressure on the back of the inlet valve prior to it opening.. This is achieved with volume and velocity. The air moving through the valve is momentarily interrupted as it closes, but its mass continues forward compressing a pressure zone on the back of the valve. When the valve opens this pressure acts like a tiny turbo forcing the air into the cylinder which aids better siphoning , This removes more of the exhaust gas , allowing more area for fresh charge , better VE. So what we can appreciate from this is the balancing act on porting , to big causes loss of velocity , to small loss of volume. Both are needed for optimum performance.. when achieved another benefit is being able to then modify cam timings and profiles to assist performance further. There are definitely gains that can be made, but the devil is in the detail . There is a reason why pro performance engine builders charge what they do .. hope that helps answer a few questions for you @Peter H. PS , any mods can only be properly quantified by dyno tuning when completed . To to honest i can not see how you could complete a porting process without full dyno set up to finish off.

    004 was suppose to be at the Silverstone Classic the other Sunday but decided to stay at home with the weather forecast not looking good, been sat in the garage ever since waiting for somewhere to go so this morning put in an appearance at a local classic event at Ilkeston Town Centre Market Place - 20 mins away.

    I simply cannot see anything negative to comment on regarding that car. a cracking piece of British automotive engineering excellence - we should all be positive about that

    Just for interest factor - I received my cert. of provenance from Andy Graham today. My #002 was purchased new by me back in early June 1999. The data from Andy confirms what I was told at the time. 1 prototype car produced #002 was the first European S350 to be finished, so first of 42 for Europe and the only S350 registered without A/C. If you don't have a cert. I would recommend contacting Andy Graham, as it's nice to have some additional detail on our cars. Mike S

    I have the same experience.....26 years of ownership and 52.000 km on the odo......with my '90 Esprit Turbo SE I have all the invoices since purchase in 1993; total cost of maintenance during all those years € 6300,- = GBP 5.500.- (GBP 200,- per year) incl. 1 set of 4 new Good Years; 1 revised turbo (after too heavy duelling with another sportscar); a very tiny piece broke of a turbo fan blade.... Actually the total cost of ownership (incl depreciation) are equal to those of a small 2nd family-car like a Fiat Panda, etc.

    Pleasure! Thanks @GFWilliams for supporting this little project right from the start!! After quite a few requests I'm looking to kick off an initial production run (in small numbers). If anyone would like to get in on the run please give me a shout. The plates are anodised in black, then CNC machined to design, for the eagle eyed among you note the slightly bevelled edging - My aim was to do a proper job to replace the cheap plastic you get from factory. Im genuinely chuffed with the end result, never done anything like this before, and blessed to have folks around me who can help put my ideas into action!

    Time for a brief update... I had a great day on Friday visiting Hethel with my Dad for a B&C test day driving the Exige 410 and Evora 410. The Evora 410 was surprisingly civilised and I can see why someone would love it, particularly as an everyday car or a GT sports car. Amazingly capable on track for that type of car too. But for me it really felt slow by comparison to the Exige and the steering too light. The Exige 410 was terrific though. Not night-and-day faster than my 350 but noticeably so. The main difference for me was the suspension/ride. With the Nitrons on it felt super smooth, really stable and predictable. Oh, and that titanium exhaust!! Big thanks to Jamie @ B&C for organising and part hosting the day. I went straight from Hethel to meet Dave @Hangar 111. Let me just say that Dave has been incredibly helpful dealing with my endless email requests over the last few weeks and it was a pleasure to finally meet him. Clearly a true enthusiast and obviously knew his onions. My car needs a service and to have a variety of low-level niggles sorted out that have been driving me a bit nuts: sticky first gear selection, creaking from body panel above passenger's head, replace broken strut for fabric roof, rebalance wheels to hopefully cure vibration through steering wheel etc. All rather dull but essential for me not to fall out of love with the car needlessly. And then the upgrades can begin... The visit was initially precipitated by a need (OK, perhaps more of a desire) to get the clutch replaced under warranty. It is unusually heavy to operate and rattles like an old diesel at idle. While at Hethel, I got a Lotus field engineer to approve the warranty claim so am keeping my fingers crossed that all goes through smoothly. In an ideal world, the warranty department will sign it off and give me a new, uprated clutch from the 430. If that happens I will be a very happy Lotus customer indeed. It will also allow me to fit the Quaife LSD at the same time as the clutch is out, which I have been wanting to do ever since I got the car. Once the clutch and LSD are done, that will set the platform for the first stage of my mods. Have decided to start with the EX370 kit just to dip my toe into the water. Hopefully it will give the car just a bit of extra spark and convince me that the full 460 kit is a totally sensible proposition in due course. Dave had two EX460s in the workshop at the time of my visit, which he kindly allowed me to drool over. Very neat looking installation and I am already convinced having driven the 410 that a properly set-up Exige can handle a load more grunt... Finally, Dave is going to fit the 60l fuel tank since I am fed up with the pathetic range on the current tank, which presumably would be made even worse by the power kit being fitted. I like the fact that the tank is also a bit lighter (when empty obviously!) than the standard one, although that is of secondary importance for me in this instance. I had been toying with the idea of fitting the close ratio gearing while the clutch/LSD was being done but have decided against that on the grounds of cost and the loss of 6th gear motorway cruising ability. As @GFWilliams rightly said, just add power instead. I like his style!
