1991 GTI 16v at PCA autocross in Pomona 6/27/10

The local PCA club (Porsche Club of America) put on an autocross in Pomona. I though this would be the perfect opportunity to bring my 1991 GTI 16v out to an autocross for the first time. I came in 13th out of 85 cars (this is a Porsche event, mind you!) with my early nineties 2 liter four cylinder FWD hatchback beating cars with over 400 hp in the process.

Mind you 150whp is actually around 175 crank (advertised) horsepower. The 2 liter normally puts out 134 crank horspower from the factory.

The engine modifications are listed in the video details. Mainly aggressive headwork, larger valves, cams, lightened rotational mass, 4-1 race header, full exhaust, 50mm euro intake manifold, intake and ECU chip.

Thanks! It last put down 150hp to the wheels, but it feels like much more than that :)

what are the engine mods to bring up to 150 hp?

Got a 92 16v with Neuspeed sways and KW coils. Love it.
