1500SBR, Your turbo setup sounds similar to my setup. I have a kit that a respected Australian VW mechanic setup that mounts the turbo on the passenger (RHD) side of the gearbox. The intercooler sits the other side, and feeds back to a Weber 32/34 DMTT carb setup for blow-through. The turbo gets its oil from the pressure switch via a T, and the return goes back to the passenger side Valve cover. The kit has a distributor that limits advance travel, and it is setup to work with a basically stock motor. Stock heads, stock crank, you just put a rising rate regulator, fuel pump, and bigger Pistons and Barrells and drop compression etc, and it is designed to only rev to 4500 rpm. This setup was driven 600 miles to a run, did a pass of a 14.2 secs with an 1835 setup, and drove the 600 miles back home.
Here is a pic of the headers and the setup as seen in the engine bay.
Interestingly, petrol manufacturers over in Australia, are now blending ethanol into petrol between 10% and 30%.
Good to see that the kit has some proven heritage.
Cheers
Steve
