Some new photos, everything starting to come together... Through the front bumper you can spot the radiator for the intercooler.

Also Talked to Guard, they recommended a 40/60 LSD instead of the standard 20/100 which is in my new 964 Turbo transmission now (G50/52). I might have that done right away, as the transmission is out anyway and I can have a mechanic of Porsche Motorsports work on it in Germany.

Do you think you'd need to strengthen the body as well (things like spot welding) in addition to weld on rollbar? since you are adding significant power than the body was designed for. unless porche really did over engineer this thing by 100x

I couldn't tell if you were doing anything regarding replacing the stock AFM with a MAF and what you were doing for additional oil cooling?

964TT

Good point. As far as I understand I should be fine. I would be happy to hear some solid info on this. I was looking into a full cage but decided against it for now. Might do that in the future though.


Yes MAF. The oil pump you see in the photo above is a different one than stock. Not sure which one exactly but I was assured I could run this engine all day long at the track if I want to. And I will test this extensively!

You might want to think about adding some additional oil cooling capacity as well.

Ferdinand Pietz from TTP has been doing 964 turbo conversions since they came out in 1989. He used to work under the name Lotec.
They installed an additional oil cooler on the left side in the front as big as the one on the right.

I asked him today if the car is strong enough and he said as long as you're not doing any rallies and jumps of several meters high you are fine.
To handle the power you need big brakes and upgraded suspension. I took care of that.

Yesterday I sent out three gauges to be modified. The red line moves to 7200rpm and 7000 will be at 12 'o clock. Speedo will go to 320 or maybe 340, depending on how it works out with space in the instrument. Also calibrated to get the signal from the ABS because the new turbo gearbox doesn't have a sensor for the speedometer like the old one did.
Clock will be substituted for a mechanical turbo pressure gauge, I will keep te warning lights from the clock that way.

Couple photos at INTRAX while they were building my new dampers.

Exhaust manifold (993) prepared for the turbos and the engine is almost finished. Just waiting for the titanium exhaust parts which should arrive end of this week!
Another two weeks and I'll travel to Germany to drive it back home...getting close now!
(sorry for the blurry photo, I'm at the mercy of the mechanic...)

Seats being worked on. Total refreshening and I am having the center cushions made out of black alcantara. The seats are also being painted in black semi-gloss.

Gauges being worked on...its not cheap but I couldn't resist having it all perfect in order.
Turbo gauge in the clock is just the best thing I learned reading this forum!

Some progress on the turbo gauge.
Unfortunately there is a small delay in the titanium exhaust built and the gauges need to be finished and go back to Germany. I have a small trip planned mid april so I'll pick up the car when I get back around the 23rd.
This is a real exercise in patience...

I am looking into the brakes at the moment, I have the 993 turbo big reds on the car and stainless brake lines. I understand that the 3 channel ABS from 1990 might not be the best thing to have on the track.
I would like to have the option to turn off the ABS all together and move to a more modern, 4 channel race oriented ABS system.
What would be a good replacement for the current ABS?

New dails for the gauges:
