    Esprit Picture & Video Thread

    Not sure what part you refer to Steve? Then there are the revised Y-stays that are there mostly to add extra support to the whole radiator cassette. cut and pasted from over the pond: When you take a closer look on the Esprit Turbo SE and the Sport300 cars, the front cross member had the two reinforcing tubes welded on to the Esprit Turbo SE, where as on the Sport300 they were bolted on, to make it easier to access the servo. The earlier Stevens Esprit such as the 1988 turbo, Turbo S etc, did not have these reinforcements. Extra stiffness, less flex. The next reinforcements are the body itself. If you take a closer look upon opening the bonnet, on the earlier Stevens cars, again the carb Esprit Turbo, the Bosch injection Esprit Turbo and the Esprit Turbo S, does not have two large extra reinforcements in the front compartments, going from each rear corner towards the middle of the front. Again extra stiffness. The next difference which is only Sport300, is a few extra bolts to secure the chassis and body together. Some Sport300 have 4, some 6 extra bolts. To help the thinner bodyshell on the Sport300, which were hand laid, not Variomoulded, a proprietary Lotus technique. Then there's the Sport300 gearshift cutout chassis reinforcement. To prevent cracks along this cutout and to aid with extra stiffness. Later on it was also made on to other cars. Then there's the rear engine compartment brace, which consists of two thick steel tubes, which are actually assembled of a few pieces, and bolted together with a very thick aluminium cross member. It's really solid and weighs a lot. This Whole structure sits on 4 semiconical steel mounting points welded to the existing rear tubular frame, with (4) bolts. It can all be unbolted to service the engine etc. In the video, Henry mentions the stiffer uprated suspension, 27% front and 25% rear, as well as the much stiffer bushings all around. On the S4, v8, GT3 cars, the front anti roll bar were thinner. where as on the SE it's thicker and stiffer. Later downgraded. The Sport300 dampers were also bigger and fatter to contain more oil and Work for an extended period on a track, or hard use on a public road, without changing it's damping, because of heat buildup. The chargecooler on the Sport300 is exactly the same as on say the SE and S4, apart from being grey, having the Sport300 metal plate on top, and to support the bigger T4 turbo on the Sport300, it had been cut off by 10mm on the intake hot side, as there is not room enough for the bigger turbo. The chargecooler system out front is often coupled together with the cooler that is normally used for the aircon, to aid capacity, but not all Sport300 have this, as a few were built with aircon, hence the normal SE/S4 chargecoolersolution. The seats on the Sport300 are only on the Sport300. It's not the same as on the later 2 Liter GT3 cars. These have no extra provision for race belts. Ony the Sport300 have that. Otherwise the same. The mounting seat frames are also different to thee two seats, compared to all other Esprit seats. They are much lighter, and save a total of 10 kilo for both, compared to other Esprit seats. Not all Sport300 cars have the Sport300 seats, as a few were ordered with comfort seats, as we see in later S4/v8 cars. The are wider and does not at all support and hold the driver (and passenger) like the Sport300 seats does. The turbo on the SPort300 is not the same as on the S4s, even though it's sometimes presented as having the same power. It doesn't. The S4s have a Little bit bigger turbo and the S300 is bigger still. The memcal is also not the same. The S4s have 286 hp and 296-298 hp on overboost. The S300 have 302-304 hp depending how you measure, with no overboost. This Means that on the Sport300 you can boost again and again without loosing power due to heat buildup, as the turbo does not get outside it's comfortzone, which means that the turbo is so big that it can Work with a lot more air, without compressing the air so much, that it get's really hot and overheat the chargecooling system. Where as on the SE/S4 and S4s, the turbos are smaller respectively, and they build up a lot of heat after a few hard working cycles, so that the overboost cannot come into play, and the ecm cuts the performance. Anyway, you all know that already. Just a point of the Sport300 setup. Then there are the brakes, which are bigger, thicker, better ventilated and better calipers with more pistons and cooling fins, as well as no foglights out front. Instead the openings in the front fender are used to aid cold air onto the brakes. At least one, possibly a few Sport300 were built using the "old" Stevens doors. old handles etc. Not the later Opel/GM door handles etc. Some Sport300 does not have alcantara around the instrument binnacle, most does. Plus larger gauges for speed and rpm, speedo going to 300 km/h. The Sport300 not only had ported cylinderhead, but also bigger inlet valves. The S4s received that same cylinderhead. Some Sport300 have the double headertank in the rear, some had it moved to the side. Others used the plastic version later found on the following cars. Some Sport300 had leather steering Wheel, some had alcantara on it. Btw, the intake hose on the Sport300 going from the air filter box to the intake of the Cold side of the turbo, is much larger to attatch on to the bigger Cold inlet on the larger turbo, as well as beingmore conically shaped. The fuel pressure regulator on the Sport300 is a modified SE one, with a dent, so it gives a slightly higher pressure. Also the fuelpump in the right hand side fuel tank, is uprated to deliver more fuel (higher pressure). Only on the later Sport350, the tubular rear frame were uprated in thickness, not so on earlier Esprits. That Sport350 also got the thicker anti toll bar from the Esprit Turbo SE back. The gearshift on the Sport300 were an in-between version, being slightly shorter in throw and a bit more precise. The best though is the very latest Esprit V8 ones, which were totally redesigned to have a different endcasing on the gearbox, with one cable on each side, no translator and the gearmaster unit under the cabin were of a totally different design with no sloppy rubber bushings, but a direct pull in each cable. Can be retrofitted The front bumper on the Esprit Sport300 may look like the SE one, apart from having Integrated side pieces a la X180R to aid aero, but it's not, as it's made in one piece, being much lighter than the other bumpers, incl. the Esprit Turbo SE, which it otherwise resembles. The deeper front bib is also first introduced on the Sport300, to aid stability with less air under the car; more suction. lowering is 15mm on the Sport300 suspension. Then of course the specific Wheel arch extensions also only on the Sport300 as well as a modified S4 engine cover to keep clear of the rear bracing. I am sure somone else can edit this if any errors or add the remaining differences. Kind regards, Jacques

    Esprit Picture & Video Thread

    Must see, must have... Apart from weight being told with full tanks, this is a very well made presentation of a true superb sportscar. possibly one amongst the very top 5. It's not about having more than 1400 Hp or along the lines of that. It's about the Whole package, the looks, the lines, the dynamics, the performance, the balance, the aarrhhhh, wish they were affordable. Finally Henry makes a nice Esprit video, rather than the endless line of Chaos cars from germany. Well done Henry!!! Salutes to you for the video,your recording team and last, but not least, the Lotus Esprit Sport300 ! Kind regards, Jacques

    S4s tyres?

    Not sure I understand what you say Ian? Kind regards, jacques

    S4s tyres?

    The Proxes T1 is not their best tire. I've been through a few sets on another car, and won't be buying them Again. But the Proxes Sport is a much better tire. A bit stiffer sidewall, better traction, better grip and drains okay when surprised by a serious downpour. And surprisingly it lasts fairly okay. I've just bought a third set of those for the Esprit. They do make them in 285-35/18 and 235/40-17 for the S4s and V8 Wheels in 18 * 10 rear and 17 * 8,5 front. So a matched set. Surely far better than the Kumho mentioned above, which tends to slip much earlier. I have a set of those too. But in all fairness, it's an okay tire. Kind regards, jacques
  6. Hi Tim, A few things to look into (like I did on my Esprit): * light switch, clean. * pod control module (relay at the relay arm and which on my car is the green relay) , can sometime stick and can usually be cured with good contact cleaner and a bit of pluging in and out a few times. * Pod delay module, placed at the front of the car, next to one of the head lamps. Unplugs and unscrews and can then be taken apart (black sticky stuff sealant can be reused), and inspected for brown or burnt out special transistors, marked Q1 and Q2. Can be bought after some looking around, but can be real hard to find, so better preventative measures. No newer versions of these were made. Separated solderings may be found as well, because of uneven bumpy roads Better cooling plated may be added to these parts indicated with red arrows, so they last longer. A bit like for example the mosfets on a Class A amp like the Musical Fidelity A1, which also can burn out because of insufficient cooling paste. in this case of the Esprit, an aluminium cooling plate together with cooling paste will Work. * Clean all connectors with electrical cleaner as well. You may want to repeat this step two or three times. * General notice. Usually it's a bit of a bad contact at the pod control module at the relay"arm", or relay-console. Seldomly it's the pod delay module, nla. but can be repaired at most instances. My Esprit Works so, that upon activating the retraction of the head lamp pods, the lights go out, then a delay, then the retraction. This to ensure that no warm lamps are retracted into the bodyshell. Kind regards, jacques
  7. I second that. A real Labour of love. I hope that you can get the time it needs to complete this enormous project. Deep respect! Kind regards, jacques
  8. A Little teaser of the new smaller tires on Little Red Riding Hood. Seems to suit her just fine. And the 315/30-ZR18 have exactly enough space under the arch. Haven't had a chance to drive the car, as it's laid up for the Winter, so Suspension is rised compared to normal, so will lower Again once driven. Anyway, looking good I think, and nice and sticky rubber. Kind regards, jacques
  9. Congrats on your new car. The SE model, in my humble view, is the nicer model of them all, being updated in looks from the earlier Gugiaro cars, but not as sanitised like the S4 onwards, that they lost their "hard" look. And the SE will have a different instrumentation binnacle, than previous cars, including a gauge to show boost and the super advanced 3-step ice warning system, plus a green lighting digital clock I believe that Lotus called the tacked on little extra pocket on the storage compartment between the seats, a "CD-holder" USA SE cars will often have a Little "chargecooler" sign attatched to the rear of the car. I believe from having looked at a friends 1988 Stevens Esprit Turbo (no SE), that the larger fog lights are doing their job better... But the SE model will have two oil coolers, one each side, behind that front bumper, while the 1988-1989 design non-SE models will only have one, centrally placed, in front of the radiator pack, an dvisible from the front, looking through the bumper. The connecting oil line between the two oil coolers is in the frunk, right under the front upper edge of the body, just in front of the bonnet. To aid cooling air to the two oil coolers, the SE-cars have a dedicated airguide intake hole in both sides of the front bumper, as well as two, one each side, on the side of the front bumper, to get rid of the heat. So, I would have a look, and make sure that those two oil coolers get the right amount of air. And while you are at it, you may think about lifting down the whole radiator pack cassette, and clean all of the debris, mud, old leafs and whot not, out from in between all three radiators. Not really visible from the outside, but once you take them apart, you'll be amazed how the car will run and not overheat with all that crap in there. Plenty of advice floating around here on the matter. The only possibility for annoyance is twofold: one being the aircon system have to be emptied. Not a problem if it's already empty, like many are. And secondly, that the two oil coolers have to be seperated from the oil lines coming from inside the chassis. Since oil coolers are aluminium, and oil line fittings are steel, they will most likely have corroded together, unless a nice previous owner or a mechanic, have had them undone on a regular basis. Worth doing anyway. Note that new correct Setrab oil coolers with fitting both up and down, are pretty steep from Lotus, but there are British part suppliers who will supply them at a far more resonable price. Just two more things from the get go beginning of ownership of an SE: First is to drain the coolant (both systems - engine and chargecooler system being seperate, and look for corrosion in the double bottle in the engine compartment (plus the plastic one on the left side of the trunk, behind the carpet, which can seldomly develop a crack). Either clean and preserve, or get an aluminium double bottle. Sometimes the two bigger connecting pipes to the chargecooler itself are reversed and prevents the system from cooling enough. Secondly, look at the chargecooler if it's actually doing it's job in cooling it's seperate circulating system fluid, by means of an impeller (black type) located under the induction, left of the middle of engine (look in Service Notes), where the old school ignition rotor was located on the carb models. Often this little impeller will have to be renewed (easily done) on a regular basis. Or remove completely, blank if off and install an electric pump (many good tips on that here). Makes the Whole system a bit more efficient, and I haven't heard of any break down going electric (which I also have). The chargecooler should feel cool to the touch, unless having been standing for a while, and soaking heat in general. Finally, If you use the aldl cable and connect it to a laptop in the car or in the luggage compartment in the rear, using say Freescan to read out all sorts of data, resetting error codes etc, remember to allocate a specific port in Windows. If not, the program will not start up and run correctly. Other than that: ENJOY !!! Once bitten by the Esprit virus, there's no cure known to mankind, so be prepared Mehr gas geben!

    Stevens wind deflector and roof bag

    My Stevens SE 1990 came with the fiberroof and the Wind deflector in a bag as standard. No glassroof. It was born as a full option car with all leather inside, Wind deflector, headlight washer system etc. Kind regards, Jacques

    What made you UNHAPPY today!

    Very sad day around my Waters, as a freight train loaded up with trucks full of empty beer bottles flew off the freight train, while crossing our big bridge in the middle of Denmark, because of a serious storm today, and hit a passenger train, killing 6 and injuring 16. Divers are now searching for further parts or persons in the sea, during the night. Biggest accident in 30 years. Life it seems, is very beautiful, but also very fragile. Jacques

    People's reaction to the Esprit - what's yours?

    Just had a elderly Porsche 928 guy driving his 928 stop me on my bicycle earlier this evening on a pitch black back road, asking me: " Well arn't you the guy with a red Lotus Esprit? "yes". "well, you are so Lucky. It's so much nicer than my 928". "Thanks". Kind regards, Jacques

    I've now had my Esprit SE for a Little over 5 years. Pure pleasure. Never let me stand on the road side. Never needed to be towed. It's from 1990, so near 29 years old, and what's gone wrong since I bought it? 1/ Clutch slave cylinder began leaking (while stationary). It was the original, and I got a new one for 5,60 GBP and one hour to swap it myself. 2/ blinker/light stalk lost it's high beam overtake wire after only 24 years. Bought a new one for 32 gbp incl postage and 1 hour to swap it myself. 3/ Light pop up dowles in light motor gears pulverized (they are American) after a measely 28 years. New delrin ones (from America) for 35 GBP and 2 hours to swap it myself. That's it. Lot's of tickets, usually serious. Nope, not even one. Not a single ticket as well. Pure pleasure. Think of fragile 911 gearboxes, warped crankcases on 911, IMS bearing on 911, bad cooling on both middle ones leading to worn bores on 911. And... Just to put it in perspective. I notice that recently (as in the last 2-3 years), many Porsche owners seem to be bored and go look for... Lotus But so what? It's a sportscar and it would be strange if it didn't take a toll on the car, driving like a crazy all the time. Not much to think about really. Go get it. Don't let that envious prius driving neighbour put you down by saying that a Lotus sportscar is a mid-life crisis. He have no idea of what he is talking about. Just go get it. Highly addictive and highly recommended. Kind regards, jacques
