whats the diffence in model numbers between the 3.3L 964 turbo and the later 3.6L 964 turbo??

They are both 964 turbos. There's the 3.3 and the 3.6.
As said before, the Turbo 2 and 965 refer to both and are colloquial, not official.

I don't care what you all say -- when one rolls up on me, I politely get out of the way and call him, MISTERRR Turbo (all due apologies to Mr. Poitier)

The 3.6L 964 Turbo is my ideal car - shame that because of the limited number produced in the UK I'll probably never be able to afford one.

Even though the chassis number starts 964 i use 965, it just seems easier when i'm not in it and talking with non-porsche people to then follow it up with "the turbo one, like in Bad Boys"

It was the turbo version that shut down the 4 valve heads for the 964 that
were developed ! Just not enough thermal capacity for 4 valves and air cooling
plus turbos .

Leaves me with mixed feelings .

On this same topic, can someone provide engine platform details of the 94 3.6 turbo. In particular, is it single or twin, does it use a 930 intake manifold or the later plastic 964 intake etc.

The 964 series Turbos are also identified with the "965" designation.

In April 2003, I contacted Paul Frere, author of Porsche 911 Story, about the application of the "965" designation to 964 series Turbos. From his home in Monaco, Frere sent me a detailed description of the 965. He concluded his description with the assertion that "it is true that the 964 series 3.3 and 3.6 Turbos are sometimes known as 965 among the Weissach people." I have an analogous analysis of the application of the "965" designation from Peter Morgan, author of Original Porsche 911.

The debate about the legitimate application of "965" follows from a failure to distinguish an object and the object's name. The 965 car was short-lived, but "965" survived to become the name commonly used to refer to the 964 series Turbos.

Mines actually a 966.

The 3.3 and 3.6 turbo engines are similar in respect to ignition, fuel injection, exhaust, single K27 turbo, etc. The differences are in the engine case, pistons, cylinders, heads, etc. The case is the same one used on the 993TT and the 996TT,GT2,GT3 although internals vary along with heads and everything else.

There is a lot of info on this forum you might want to do a search to learn more.

It's a Single plug engine with the intake basically the same as the 91-92 3.3. It's still DME-less like the 930 and 964 3.3, so it's not as though they turbocharged the 3.6 C2/C4 engine.

If you have access to Mr. Frere could you ask him about how he derived to the number of turbos manufactured? We seem to have a conflict compared to other sources and serial numbers. Forget about it if you think he might take offense to the question.

I contacted Paul Frere through Road & Track, cobalt. I asked for his assessment of the application of the "965" designation after I had corresponded with Peter Morgan about that designation and after several individuals had expressed their dissatisfaction with Morgan's claim (which was published in an issue of 911 & Porsche World).

If you have a "conflict" with Frere about "the number of turbos manufactured," then I encourage to contact him. I'm confident that he will not "take offense to the question" and that he will provide you with evidence for his figures. Of course, you may want to contact the authors of the figures with which Frere's figures disagree.

Ok. That is true, but still incorrect. Many people( Weissach or not) insist in that designation, we don't need Paul Frere to tell us that. Type 965 was a 1988 planned range topping four cam twin-turbo 911 and the planned marketing designation for Type 965 was Type 969. No discussion. (see Adrian Streather or Karl Ludvigsen description in this thread) After this, people can call it what they like. Even 966, like Jerry

Doc V.

I'm intrigued by your assertion, zicoramone, that Frere's claim "is true, but still incorrect." What he claims, then (if I understand you correctly), is true but false.

The point is simple, zicoramone: a name is different from the object that it designates. Like Streather and Ludvigsen, you focus on the object--the 965, "a 1988 planned range topping four cam twin-turbo"; I've noted that the "965" designation--the "965" name--has several verifiable applications and that each of those applications has currency. In his letter to me, Frere describes the 965--the car--before noting that the "965" designation is used among "among the Weissach people" to identify 964-series Turbos.

Like you, I have read the relevant works of Ludvigsen and Streather. Unlike you, however, I am not willing to use their work so hastily--and to make such a blind appeal to them--to close a discussion--particularly when such an effort, punctuated with "no discussion," is one which is based on a fundamental failure to differentiate a name and its object.

I suspect that you will continue to refer to 964-series Turbos as "964-series Turbos"; others, however, will use--and have grounds for the use of--"965" when they label their 964-series Turbos.
