I was contacted by a local racer about a month ago to get some fabrication work done on his Porsche. After about 3 weeks of work I finally finished up the last bits tonight.

This car is a historic LeMan's race car. It was built in the 80's and designed by a Porsche engineer by the name of Lee White. At the time it was considered the most advanced car on the track. It employed a lot of neat little tricks for making extra power as well as some clever engineering into the body to make it one of the dominant chassis on the track.
Some time ago this guy acquired it and he decided to restore it. This involved putting the original 2.275L 4 cylinder turbo back into the chassis and fabricating all of the necessary piping that goes with it....and that's where I came in.

This was the car in it's original skin back in the day. It was a tubbed out 924, but now it is a complete tube frame chassis.

Stainless steel exhaust. No dump tubes were added yet

Here is a photo of all the completed parts attached at that time (anything that looks like a pipe or a manifold was made by me)

New inlet for the intake manifold. The manifold also had to have new brackets made so it could be lowered to clear the chassis brace.

The dump tubes were finished up today. With exception to the distortion from welding, everything fit together pretty well after the fact.
The manifold was purged internally with argon to make sure there was no contamination. I felt it was necessary to do this since I was working with 321 stainless and this would be the area under the most stress and heat.

I'll be taking a trip to NJMP next month to watch it get tuned up and do a few laps. I'll also be posting a video when the car is back together and running.

Finished up this intercooler build on a 944 turbo the other day.

Stock IC piping. some sections were crushed just to make room for the piping between the hood and chassis.

All finished

Only thing left to do is weld on some brackets and add the Tial BOV, but all the difficult stuff is done now.
