Which parts to keep for 3.6 conversion to early/mid year car?

RideShoot&Drink · 03-20-2006, 11:00 AM

Hi all!

I might be one step closer to my dream of owning a lightweight (early or mid year) car with 3.6 in the back. I purchased crashed 92 C2 and the car is pretty much complete. Good engine, tranny, interior, brakes, suspension. Another words it's complete with some front end damage. Therefore, I have a question to people who have done those types of conversions. What are the parts that worth keeping? Engine along with harness and electricals, but that's obvious. Tranny? Brakes? Suspension? C2 oil cooling? Can any of those be adapted on early/mid year car at reasonable coast? Please, let me know what you think.

Many thanks in advance!

depending on your fabrication skills the sky's the limit......but a 3.6 coupled to a 915 tranny is a torque junkie's dream.....

well...that's the idea, but can I use any other parts from 964? Brakes? Adopt tranny? 964 oil cooling?

A 3.6 will need an external cooler set up...in most cases two.....

so, there is no way I can use 964 cooler with fan or can I?

You can. But it won't be enough if you don't also have a 964 front end. You'll still need two coolers.

The reason the 964 cooler is so efficient isn't because of its size; it's because of the way the 964 nose is able to move air through it.

My current car with 3.3 turbo has two Carrera coolers, but I haven't noticed much difference in temp when I was running just one cooler. Why 3.6 would be any different?

I've run a single Carrera cooler with a 3.6. It was okay for street driving on cool days. When the temps got above 90, or running the AC, or when I was on a track, the Carrera cooler (plus fan) was not enough.

With two coolers, it still wasn't enough in track use. I finally had to do some extensive ducting to make it work.

Still, the twin cooler configuration is not as effective as a large, bumper-mounted cooler which is right out in the airstream.

Believe that all the 911 engines up to the 964 has a oil cooler bolted onto the engine. When Porsche made the 964 they for some silly reason decided to put power steering on it and deleted the engine oil cooler for the power steering pump, which was bolted on in this space.

This is why you will probably need an extra or larger cooler when going with a 3.6 engine, no matter what you had before unless it was larger than stock already. I have a 3.6 and can drive it on the street with the stock cooler but once it gets warm here in Phoenix it was too much. Front cooler is going on shortly.

Gentlemen! Thanks for your explanation on cooling. What about the rest of the stuff? Can I use anything else from that ill fated 964? Brakes? Can they be adapted? Should I keep the gauges? Fuel pump?Anything else I cant think of now. I would hate to buy parts later as I have a complete (but crashed) car now. Once again, thanks for your input.

The brakes can be adapted w/ a lot of effort, I don't feel that it is worth while, but it can be done.

The 964 and 993 mounted their oil coolers and fed them differently from the 911/930 series

In this pic you can see a second drivers side cooler mounted, the original passenger side is similarly mounted

You can see that they are mounted side saddle to 911/930 coolers.

They are fed from the central front mounted intake, and exhausted though the wheel well. This is a very efficient cooling method, but requires a lot of fabrication on a 911, it is well worth doing.

Bill, what are the applications for 964 brakes now besides 964? Is anybody using them for the conversions or I can just throw'm away?

They are the Rodney Dangerfield of brakes, they get "No Respect"

Yes, they are a great setup and very appropriate for a 911, but they are sych a PIA to mount on a 911 that I would rather go in another direction(993 brakes), other apps? well for appearance sake, mounting them on Carrera rotors isn't a big deal.
