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.

Nice Steve. Sourced from the continent? And whose 964 did you have a run round Silverstone in?

Steve,
Looks like a great starting point. I'm sure Paul is pointing you in the right direction, but I would do the following (in no particular order), which will get you pretty close to RS feel.
1.) De-cat and cup-pipe
2.) Drill airbox
3.) Replace rear blower with bypass pipe
4.) Steve Wong chip (or a visit to Wayne Schofield)
5.) KW Clubsports inc topmounts plus suitable set-up
6.) Front strutbrace
7.) Strip interior and doorcards, replace with Appbiz RS interior and doorcards
8.) Half cage and harnesses
9.) 993 calipers front and rear (Big Reds are overkill), 928 S4 front discs, standard rear discs, remove proportioning valve, fill with SRF fluid and Pagid RS29 pads
10.) Set of Toyo R888s
11.) Replace suspension bushes front and rear
12.) Decent seats
13.) Cup steering wheel
14.) Strip as much weight as practical eg rear wiper, large screen washer bottle, engine undertray, brake dust shields etc

All should be achievable for under £10k. Clearly you can go silly with the spec, but you're into the realms of diminishing returns.

Have fun with it !

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

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..

As a fella who has imported or been involved with people who have imported quite a few cars from Japan over the years the following should be remembered.

1. Supercars/sports cars generally are imported as LHD mainly because it shows you are 'cool and wealthy' to drive slow and LHD, and zero to do with which side the wheel really should be on, or the purity of the drive.
2, So so many Japanese imports have either sat for many years because of the Japanese very strict MOT, or blatantly have been clocked.

Whichever. Great way possibly of getting a good car. Just carefully check her out whilst embarking on any work. smile

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

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

It may not matter but in case you weren't aware FIA approval had been removed from Pole Position seats (not all variants though, so search for more specific info if needed).


I look forward to seeing the project progress. What age is the car? Early or late shell/rear suspension mounting points? Aluminium or plastic induction pipes?

Interesting. I have an early 1990 car. I knew about the 1993 car having a more sorted engine but did not know about the different shell and inductions pipes. What are the pros/cons?

The revisions to the later engines centered on cylinder base, cylinder head and through bolt sealing. The later plastic inlet manifold was lighter and I suspect was cheaper to produce, the quoted Hp figures for both manifolds are identical, though some seem to think the later plastic item is more efficient.

I'm aware the RS got some very limited seam welding around the rear suspension pick up points. If anyone would like to elucidate on the late shell/different rear suspension mounting points, I'd be interested to hear what the differences are.

Edit to add. FIA certification has always only existed on certain Recaro Pole Positions (ie not the leather covered items and furthermore only when used with the correct side mounts specifically specified by Recaro). There were issues last year whereby the FIA revoked their certification on all Pole Position seats. As I understand it any new PP seats or those manufactured within the last five years will be supplied with modified/the correct side mounts to ensure they are FIA compliant.

The post '91 engines had head sealing rings but the engines are otherwise the same. The chassis mounting points are different only because the cabriolet was introduced but its not a pro or con. Likewise the plastic intakes, cheaper for Porsche to produce and a touch lighter but other than that no difference.
O/P the RS engine mounts and short shift are a good mod, also the single alternator pulley. I imagine being a Japan import the car will have AC which can also be deleted.

No apparently the 93 cars had an engine closer to the 993. Def not pre 93 and you have to be careful as some 90.91,92 cars that were sat at dealer forecourts were registered in 93 and aren't real 93 cars. 964 was a very expensive cars compared to its pier group at the time and wasn't a good seller.

Interior quality puts most modern Porsches to shame.

No late 964 was fitted with the 993 crankshaft, rods or pistons or the self adjusting/lighter valve system. All 964 engines are essentially the same including the RS. Various trim parts on the early 993 cars can also be found on late build 964's but that's as far as it goes.

Interesting fellow at JZM told me the 93 car had a substantially updated engine which does not leak. Pleased if you're correct!
