Rob:

Make sure they used forged pistons, not the cast stock pistons, on the rebuild. JAE (www.JAEParts.com) has JE forged pistons for an Esprit.

Hi Guys. On any V8 rebuild you must use forged pistons and the Steel studs instead of the bolts for the cylinder heads, cures any liner or head gasket problem. They are available from J.A.E in Goleta california. tel 805-967-5767.

Bought my Sport 350 from Nick Whale's - very knowledgeable.

I have e-mailed all the specialists listed and some extra ones that are not for prices and as soon as they come in its getting booked in and done however I was thinking that while the engine is out this might be the time to do a few mods to increase the power output of the engine.

however I am a little concerned as I have read the lew guide to increased bhp and it leaves me a little worried as it does say that the unit is designed to have 350 bhp at around 6500 rpm and to increase it from this would risk damage to the unit.

so what I would like to know is what sort of sensible mods should I consider that are not going to leave me with a blown unit in a few years time.

and by doing things like putting forged pistons in increasing turbo performance where should I draw the line I dunno bit of a novice in this area will bow to others knowlege on this one.

I would like to be able to get this job done together with the mods for around 5-6k seeing as I could possibly get a rebuild done for around 4k dependant on what they do could have around 2k of mods done.

as always all info welcome

I sent out a load of e-mails to various specialists to see how much I would be charged for the work to rebuild my engine this is the first quote and I am encouraged at how low it is in comparison to what I thought it might be :(:P so the question is what do you think and what reputation have south west lotus got amongst the comunity can I trust them to to a good job ect ect :(

please let me know your thoughts.

Rob,

Have you thought of asking Lotus at the factory?

maybe Kato could give you a contact

Just a thought.

I know your dilema i had my engine rebuilt by someone with no lotus experience at all!

it was done under warranty from the garage that i purchased the car from. I had the choice of having their mechanic do it or if I wanted a Lotus dealer to do it they wanted a contribution to the Labour charge which is considerable at

Hi Rob,

Spoke to Pete at PNM, with his workload, he cannot undertake a V8 engine rebuild unfortunately.

As for the sealant, he has good stocks of the wurth product. If you ring him back, he can send you a bottle or two.

Also word of advise, NEVER take the quoted time as gospel. You only have to come across a few problems with your engine and problems with other customers' cars then before you know it, they've had your car for 4-6 months! There's no way I'd put my car in for an engine rebuild to any company if you want it back for Donnington or the rolling road day. Also if there was any chance that it was ready then you'd be running the engine in anyway so you'd miss the rolling road!

Hi dave I will give pete a ring in the morning and aquire the wurth product but on the flip side of this I have spoken to almost every one today that is listed on the specialist page and aside from nick whale south west and morland jones the rest cant undertake the work for various reasons, (time scale required over commited ect ect ect)

I have in addition spoken to pat thomas at klevedon motors and although I dont want to take it there he reckons he can match south wests price which would have the advantage of additional warrantys exactly what these are remains to be discussed.

will keep you posted

as for milton keynes I am sure that if the original work time quoted remains largley unchanged i could run the engine in during march ready for april.

I hate it when companies say they'll match a quote. Why don't they come up with their best quote in the first place? I suspect to see what they can get away with. I don't like these sort of companies but that's just my opinion.

As for the Milton Keynes Rolling Road, why don't you wack up your boost to see what BHP you get. Doesn't matter as your getting a rebuild anyway! Only joking, on a more serious note, try to get more recommendations before committing.

I'll tell Pete your going to ring in the morning. Sorry Pete can't quote you just hope he pulls his finger out if my engine ever needs rebuilding.

If it were my V8 engine, I would push Lotus direct and see if they can do a good deal. You can't beat the company who actually made the engine. I think I would even do this based on my friendship with Pete at PNM.

4 cylinders though, PNM know these better than most in the business.

Ok decision made I have a quote from pat thomas of 3.5K inclusive of VAT :) for a full rebuild thus curing the water loss problem and in turn doing the liners :( and the job starts monday. benifit of having it done here is no long drive to devon twice and the waranty is full lotus parts and labour.

On top of this I have set asside 1K for mods

Rob,

This sounds like a good deal.  My V8 is awaiting this work, tensioner came off, still waiting to find out how much damage has been done. 

Where abouts in Essex are you?  Assuming mine ever gets back on the road, the sight of two V8s in formation would be something to see!

Cheers

Russ

If your getting hoses made up, Iam in the process of getting SFS silicone hoses made up in red. Rob, if you send me your hoses, I'll get them made up for you and also I'll get you a huge discount as you'll be offfering use as a mould. I held off doing this as my car would be off the road whilst I took off all my hoses.

My number is 0771 775 0453.

Also if you're upgrading and wanting billet alloy wastegate capsules, I can get them for a fraction of others and also cheaper than standard Lotus mild steel ones. I can also get hold of dump valves etc. If you're thinking of any upgrade, then let me know, Iam sure I can get the parts cheaper than anyone else.

called in to see how things were going today, an all going well but what i do know now is exactly what was causing the water loss.

along side the head gasket flaw, the engine was still sealed with the original loctite sealer and it had startred to degrade between the piston chambers sections definate water cross over taking place not very much but there none the less.

examined the clutch plates and they are quite well worn as you will know AP clutches are 1200 quid from lotus but pat reckons he can have the plates re lined for around 150 ish

anyone else had this done?

I would try this route if you can't get another source. I've heard this being done quite a lot. I didn't want to suggest this as some regard this as a half hearted job. If Pat recommends it then go with his judgement. After all he's the expert!

YEEEEEEEEE HAAAAAAAAAAAAAAA

Got the car back today after minimal delay due to a part inavailability but she is back and WOW she runs GOOOOOOOOOOD

few mods done in the process so will update the garage in a moment.

I can confirm though that the price Pat Thomas quoted on the phone to me for a full engine out strip reseal liners and assemble engine and refit including all extras like broken nuts and bolts ect ect came in right on the money

bob,

Thats great! Sounds like a good job and reasonably quick as well!

one thing where did you get the turbo hoses?

Cheers Andy

ps car looks good in the garage new rear lights an all!! :lol:

<{POST_SNAPBACK}>

The Turbo hoses were made locally by goodrich who make the brake hoses basically we adapted the principle and used stainless steel unions to the engine and to the turbos they are aeroquip type hoses pressure tolerant to 4000+psi

the water hoses are again high pessure 4000+psi reinforced and lagged with heat shielding resistant to tem extreems of 1000+degrees
