This is the next race car build!

A couple of developments on this car. Two weeks ago I got the R-134 adapter and was able to get the AC working. That was huge and made this 924S quite comfortable to drive. Except for the rattling under the floor board at idle. I was concerned that might have been torque tube bearings but I went under and listened to the cat. Sure enough the material inside the cat is rattling around. The cat is an aftermarket shorty with the label CATCO. A couple of nights ago I decided to pull the pipe and muffler post-cat and try to get that loose material out. This car is registered as antique so no emissions checks. Of course the three nuts and bolts on the flange were rusted solid so I had to grind off and drill those out. After wrestling the rubber hangers under the rear bumper off, I dropped the pipe, muffler and tail pipe (all aftermarket). Then I'm looking up the short pipe post-cat and seeing this white honeycomb material inside the cat all busted up. So in with a threaded rod and a lot of jabbing. Then start the car up and blow stuff out. I did that about six times until I'm down to one lump just slightly bigger than the pipe. One last start and I hear the lump wedge, constrict exhaust and then... POW! it blows out louder than a shotgun! Now the exhaust is unrestricted and flowing really well. And reving the car gets me to thinking...

This '87 924S runs really well, the EFI is easy to work on, it has all the desirable suspension, 5-speed transmission, 2.5L Porsche engine, etc. The only downside is that it classes in F Prepared when you strip it down and go light weight. But rather than dealing with CIS 2.0L 924 in D Prepared, I'm going to put on my big boy pants and jump into FP

I'm developing my plans now on how to go about the build. Timeline, parts to be removed, parts to be sold or retained for my 931 restoration. Performance parts to be purchased or fabricated. I'd like to have this car ready for SCCA autocross for the 2018 season. I want it to be super light weight. HP isn't that important but suspension and handling is. Fiberglass body panels front and rear fenders. Lexan windshield and replace rear hatch glass. Aluminum race wheels. GOOD shocks, struts and springs. Fuel cell for sure.

I'm going to drive it in stock form this summer and fall. Maybe a couple of regional autocrosses in stock class. Then this winter I'll start disassembling the car and storing or selling parts. AC system, wiper assembly, headlight assembles, door cards, side windows, rear seats, interior panels, dash, etc. All that will be coming off.

Stay tuned gentlemen
