964 - Project

[Steve Rance]

Paul Mclean at GT classics found me a lovely 964 recently. Original factory Limited slip diff with sunroof delete. Very low miles - 36,000. A rare thing. I've always loved these cars and a drive at Silvestone in a mildly tuned one recently just fed the yearning. When Paul found this car, it was too good to miss. It will be used regularly on road and track and is currently in build with Paul. These is so much fun at to be had in these little busses. Spec to follow.

[Steve Rance]

Gentlemen thank you. The car has just arrived from Japan who - although drive on the left - are Aparently purists when it comes to 911's and often spec them LHD.

Jamie - thank you for the advice. Essentially exactly what I'm building but with one or two trim mods - quilted mat leather on the Pole positions etc..

[Steve Rance]

Yep. All done. Very good source of potentially very good cars.

Love it steve and the steering wheel is on the 'correct' side. Much prefer the drive of a 964 in LHD. 36k miles is seriously low. Mines on 62k. Got some cup mirrors for mine and rear wiper delete bung looks much better.

Had 9E go fully through my car and fully upgraded. Enjoy

I was considering cup mirrors. Do the give a decent vision range? I was worried that they would be a little restricted.

[Steve Rance]

Just an update. The car is in build now. Paul has advised me that the car is a very original example and the mileage and provenance stacks up so we've decided not to do anything that may compromise that going forward. So things that I would have done - removing sound deadening etc - have been shelved. Spec will be;
Big red front brakes
993 C2 Rear
RS anti roll bars
Lightweight RS flywheel
RS engine mounts and mounting bracket strengthening plate
KW clubsport and andjustable top mounts
RS carpet set
RS door cards
Heigo cage
Pole positions
Momo removeable wheel
Radio blanking plate
Engine remap. Exhaust system unchanged.


Set up will be RS and a fair bit more.
Road Tyres to be decided. Road wheels Fuchs RSR
Track tyres to be decided.

Currently trying to source proper cup door mounted wing mirrors. Can anyone help

That's it - will update soon

Thank you. We may have to find another solution then!

[Steve Rance]

Very very nice. 3.8? Might I ask where you sourced your wing mirrors?, I'm trying to source exactly those but for LHD

A word to the wise Steve. If the RS carpet is as per original then it will not fit correctly/well if the sound deadening is left in place. Also a cat bypass is a real benefit if you are going to the expense of having Wayne work on the mapping...

Just re read your post re the cat bypass. I know that i'm in the minority but years of racing has left me with Tinitus which gets worse if im not careful so I prefer a quieter life inside my cars these days!

Red is fastest Steve ,nice looking car and very addictive





The one mistake was the RS logo on the carpet which I did not order !

Lovely car.

Nice list, should be a nice setup once its done. Couple-u thoughts:

Big reds etc - this gets quite expensive to do correctly and adds a chunk of weight, with a lightweight C2 and experienced racer that doesnt need to over brake you will be able to get the standard setup to work just fine with good discs, pads and fluid.

Have you seen the Rennline adjustable motor mounts? They seem a good compromise between RS and Wevo and allow a bit of tweaking. Also there is a semi solid gearbox mount insert if you want to firm up the front of the engine a bit too, the original one is probably a bit baggy by now. http://www.rennline.com/Tuneable-Semi-Solid-Engine...

Fuchs - I assume you mean these: http://www.fuchsfelge.de/index.php?id=190&L=1 if so good call, they are proper light

Couple of other ideas: Single pulley conversion(simpler, lighter and reversible), Electric power steering (removes PS pump drag from engine and moves some weight to the other end and easily reversible if you leave the lines in place). These 2 coupled with the lightweight flywheel you mention should make things rev a bit quicker. Heater blower motor bypass cleans up the engine bay and saves a bit of weight. Lightweight bonnet and store the original one.

Good luck with the build and keep us posted.

Thanks for the advice. Much appreciated. To be honest, most of the mechanical build is now completed. I already had the big reds and adapters so there was no real cost implications. I'll look at the pulley conversaion though - good call

This thread reminds me of how great it is to be around genuine enthusiasts who are happy to share their knowledge and experiences. The 964 really is a peach of a little car. I can see now why it has such a passionate following. the level of detail and quality of some of the builds that you Chaps have painstakingly put together is just lovely. Almost each car seems individual to its owner - an extension of his/her character. I am really looking forward to meeting some of you during the year if you happen to be at any of the track days that I'll be wobbling around at.

Thank you. More good advice. When i'm running a Slip diff, i like a lot of forward brake bias as - when it's set up right - I use the diff to help settle the rear of car and trim the nose on he brakes. I'll try the brake set up without removing the bias valve and see how it feels. If It's difficult, i'll remove it. As long as the ABS doesnt lock the fronts it may be ideal for me.

I remember your slate grey car. Not sure that I ever drove it though. Those days, I always seemed to be driving other people's GT3's!

[Steve Rance]

Hi Jamie

We had a lot of problems balancing spring rates at the front to camber adjustment on the GT3 as the governing factor was the abs. To be honest, I am a little worries about this issue with my 964 because I think that the front spring rate on the KW clubsport is 340lbs which is twice what the V3 is. I want to run at least 2.25-2.5 deg of neg camber on the front so I could have problems with abs if the front bias is too high.

it will be interesting to see what happens. As you say, I can change the proportioning valve but I still need a strong forward bias.

It's all fun..

[Steve Rance]

Great thread. Thank you for positng it up. What's interesting is that there seems to be a general preference to add more rear bias to a car for high perfrmance/track work. I would be always looking to keep my bias as far to the front as possible only winding to the rear when it's damp or wet relying of my diff to keep the rear end stable

[Steve Rance]

Ha! You are quite mad my Dear Old Thing! If you PM me with your email address and I will be happy to send you a few tips to set up your bias to get the most out of your car during quali and the race phases

Here are some pics of the build so far;

Thank you Richie. Yes I am very pleased with the car. Paul Mclean is very good at sourcing these old busses. It is a very low mileage car but I did not expect it to be this clean.
