Love all the discussion!

I have enough 924 motor parts to build up at least 2 complete engines. What i don't have is any of the original turbo bits and pieces, etc.

So the idea of building a &q ...

There were no US built Kits, for the 924 GTR's. You are thinking about the D production 924 Kit car.

That was a NA car built for SCCA Club racing. Ran in Dprod, then in GT3.

Carrera, it is really hard to tell. There are a couple different pictures out there of Heimrath cars from the time frame, but you cannot really see into the car to see the cage and chassis well enoug ...

I was shifting at 7500 rpm, when the car makes peak power at 7900 rpm, so I was deliberately leaving power on ...

In car. Note the high level of abject terror/caution during the first couple of corners. Note the guys off in the grass..... All of those 1000 pound heavier 996's and C ...

Of course

I want to add, this car is stamped HR00182. I have been told that it is Holbert racing, lightweight chassis 924GTR 001, built in 1982. If that is the case, this was the car Doc Bundy drove to several ...

We will be running the GTR at the Sebring PCA race on the 2nd, 3rd, 4th and 5th.

Please feel free to stop by for a chat, and some beer.

Look for the big easy up with the red and black awning ...
