Hi!

I'm currently considering getting my dream car, a 964 turbo.

What I'm wondering is what upgrades that were done between the first 320 hp model to the last 360 hp in 1992?

Is it only software upgrades or should I aim for the more expensive -92 model with 360 hp in stock shape?

Hi Anders,

The 964 Turbo from 91 to '92 are pretty much the same. The 1993 or 1994 (us) is the one that has many changes to it. For instance, it has a 3.6L engine instead of the original 3.3. It has 18" 3-piece speedline wheels that are one of the best looking wheels from Porsche.

If you want to read more about the 964 Turbo cars, please visit my website link on my signature.

Good luck and report back on your request,

Sonny

Sonny, I've bookmarked your site since earler. Thanks!

Sweanders,

I agree the 964 Turbo is a dream porsche, we have on in the garage and although the 951 is faster, looking at them side by side the 951 always looks a bit like and ugly duckling. The 964 also has the incredible feel to it...

But any way your post was about differences....

I know on the 1992's they made the Limited Slip standard.
for 1993 and 1994 as sonny V stated they did change the motor to the 3.6L block. IIRC that was a completely different block than the one from the earlier 3.3.

Also I think the brake calipers changed color on the 3.6 Turbos from black to red (but in europe you could get them in black).

There was also a slight suspension geometry change to the back end.

Thats all I can think of, but i'm sure there is more, porsche always makes subtle changes in their cars....

Oh, I remember another one.

On the Turbo 3.6 the fuel enrichment system is better and it gives more fuel than on the 3.3L engine.

Thanks for the info!

For my money I might be able to find a 92 model, which would be my best bet. I've located one and the seller says that it has 360 hp and is unmodified from factory, did Porsche offer a "high power version" of the 965 in 92?

The 964 Turbo, type 964-770 for model years 1991 and 1992 was offered standard from the factory with 320 HP.
There were three ways to get more power from the factory,
1/. Purchase and have Werk 1 install the 355 HP engine kit.
2/. Purchase the S2 (20 only built for USA)
3/. Purchase the Turbo S (never exported to the USA).

I very much doubt that the 964 Turbo being offered is one of these three. The only way to check is to look at the delivery documentation.

Changes between model years 1991 and 1992 were minimal. The Turbo 3.6 used a turbocharged version of the M64/01 engine. However many parts from the Turbo 3.3 engine were used on the new engine.

Every 964 Turbo (1991 through 1994) was fitted with a LSD in a G50/52 transmission. The 20/100% LSD appears in delivery documentation for the 1991 model as an option but it was actually standard. This was an internal production line issue only to list it as an option.

If they did, I haven't heard of it.

AFAIK, the stock C2Ts produced about 320hp. There was a very rare S version, with more HP, but I doubt you're looking at one of those.

After the C2T they went on to the Turbo 3.6, which produced 360hp [at least in ROW form. There was also an X88 option for the turbo 3.6 which supposedly gave 385hp, but anecodotal evidence was that it gave over 400 hp.

The car I'm considering is in Germany and I plan to import it to Sweden where I live.

So it's very unlikely that it's a US model, even though I'm not sure if there are any differences between the ones sold in Europe and those sold in the US engine-wise.

About that turbo S being rare. i just found one for sale, its a 91 turbo s with 45,000 miles on it. blk/blk with 398hp he said it was 1 of a kind. it has the andial S2 upgrade.

All C2's are amazing cars. You really can't go wrong with either the 3.3L or the 3.6L.The big differences are:

1. 3.6L obviously has more displacement (more power & low end torque) totally different engine than the 3.3L
2. 3.6L came with a more aggressive cam profile than the 3.3L.
3. 3.6L-Porsche said it had a more efficient fuel enrichment program (I think the 3.3L is just as good)
4. 3.3L I believe had more color options
5. 3.6L came with 3 piece speedlines
6. brake calipers could be painted black,red or silver (options in the US)

If you can find an "S" version and can afford it, BUY IT!

Good Luck!

The camshafts on the M6450 engine (3.6 Litre turbo) are the same as those used on the M64/01 (3.6 litre normally aspirated). The M64/50S engine used more aggressive camshafts from the 930 Turbo engine. The cams used in the Andial (S2) kit are also 930 turbo part numbers.
