964 engine upgrades, who is the go to?

[C2Red]

I'm looking to sell my 964 next May/June; however, plan B if i dont receive the offers i'm looking for, is to upgrade the engine... a little.

I'd be looking at 3.8l, ITB's or someting similar to make it worthwhile, and really special to me.

The question is, who would you choose as your go to, and more importantly why, have you a direct expericence with said company?

I'm looking to make it special, but keep the reliability I currently enjoy, in 18 years thus far, two batteries, and one crank angle sensor are all that have stopped the car, its always, key in, turn, start, and go; and I'd like to keep that kind of mindest up.

TIA.

Thanks David, that’s appreciated; I’ve only a small amount of experience with 9M, and that’s from quite a while ago, possibly 10 years..
I find myself quite out of the loop so to speak

Nick Fulljames at Redtek. Ex Autofarm, worked with Cosworth F1, numerous touring car companies and within supercar engine development. His passion though and where his experience and knowledge is second to none, is with the 911 race engine and, in essence, how to get the best from each individual engine, for the purpose, whether it is for road, pleasure, track or hill climbing.

His repertoire includes the rebuild of a rare Le Mans Porsche race car and development of the XJ220 Jaguar engine. He has also had extensive experience with fine tuning engines for Jaguar, Ford, Chevrolet, Ferrari, Porsche, Aston Martin and Volvo and has worked for Brodie Brittain, Autofarm and Tom Walkinshaw Racing.

When it comes to his work, Nick personally builds every engine that comes into the business. Hence, each project will be under the scrutiny of Nick’s eagle eye of perfectionism. He wants you to get as much out of your engine as he would if it were his own.

Nick built a 3.8 on ITB's for a 964 for this chap :

IIRC that’s Frank, think we met a couple of times at Donnington, and it’s is if I’m right; a nice build.

Thank you.

There is a little write up on my 993 3.8 build here (with costs) if it is useful:

Thank you, that’s most interesting food for thought.

Id be putting money into the chassis before the engine on an aircooled. You will get a better performance return for your £. On saying that, a well tuned airooled engine is a truly wonderous thing

Thanks Steve,

I have Bilstein with H&R, LSD, Strut Brace, RS drop links and ARB's, Powerflex and Chris Walrod bushings, strengthend engine carrier RS engine mounts; anything else you'd suggest? I was thinking of bining the Bilsteins for Ohlins or KWv3, but again its only if the potential sales falls through.

Thanks

I'd say that's a very nicely road optimised (with occasional track use) chassis.

Dampers ? The law of diminishing returns definitely applies, you really do get what you pay for. The Bilsteins/HR springs/RS ARB's combination is highly regarded, and a very good compromise that blends comfort on the road with improved performance.
So with that sorted, let's get back to spending your hard-earned on the properly oily bits

Thank you. :-)

Thats a nice set of modifications. For biggest return for £ I'd reccomend a set of Tarret spring plates. They will really tighten up the rear of the car. Then i'd fit a set of big red cailipers/discs to the front - but you may have already done that? If not, i'd definately do that. It will push the brake bias a little forward if you dont do anything else to the brake mod. That really suited my driving style but it may not yours. Its a straightforward mod. RS light weight flywheel is a very nice mod. I really frees up the engine and makes it a lot more responsive - but you will need the mapping changed or you will stall regularly. The RS gear linkage kit is also a very nice upgrade or the Rothsport kit but not a massive must. Dampers could be improved but as Slippy says, thats a minefield. If your spring/damper set up feels nice, i'd leave it. I went KW clubsport. They are a reasonable damper and come with adjustable top mounts. The valving set up is vey good. Overall they are a better specced and value for money damper that the V3 but the spring rates are quite high. Again that suits me but its subjective. If i had the budget, id fit a high end damper but the benefits would be marginal.

According to Wayne scholfield's dyno (it was Colin's but not sure who's he uses now) he managed to extract 300bhp from my standard engine with a remap(with the usual exhaust mods). That was done in Nov when the weather adds a bit. Most of the time it would be 290bhp i think. It does feel a little stronger and but its no way near what a well modded engine will give you - that is not a cheap excercise. All of the above would probably cost you less than a quarter of the cost of a big engine mod.

On saying all of that - my real advice is DONT SELL THE CAR!

Good luck

Thank you, I've followed your's for a while... V nice, and I'm really in two minds about what to do, emotional investment, versus finanical, versus heart saying lifes short, get something that is a touch different.. hence looking at the plan B route. At least if I dont sell, i know the foibles of the car, and thats a big thing.

Just re-posted this as it's excellent advice

Not quite on topic but you could take a slightly different approach to making your 964 special by removing great chunks of weight from it

As it's now a desirable Porsche you may want to limit yourself to bolt on reverse able weight removal such as seats, bonnet, engine lid, wheels, battery, rear seat delete etc

I've removed over 200kgs from of my C2, only lightweight parts added are a CAT delete and lighter wheels, certainly a bit stripped out for most tastes but great fun to drive on my own. Less weight has brought the car alive, especially the weight saved on the wheels

I should easily get down to 250kgs removed with a few more bolt on lightweight parts. The last 100kgs or more after that I'll have to get serious and start a full nut and bolt rebuild it up from the bare shell

Thank you, been there, did some of that; went for southbound RS carpets, rear seat removal, 100cell cat, RS door cards, and more. But, i'm kind of over the hardcore that it bought, and went down the kind of GT route with the bodywork and interior.
The engine remains the aspect I'm most interested in, and getting additional power to suit my mindset.

Thanks

Phil Hindley at Tech9 has a very good reputation, especially with 964 engines. The previous owner of my car had a rebuild by Phil, such a sweet engine, 300bhp, very tractable, loads of torque.

Thank you.

I'm still in two minds, but 18 years is a damned good run. If I dont sell, I'll look at Tech9 as well as the others mentioned here.

I have a winter to look forward to....

Thanks
