Go to a paint store like ace hardware and pick up some toulene or tolune. Its 116 octane by itself. When i run it i use a 3 gallons of 93 to one gallon of that which concentrates it to 100 octane. Dont run it straight. Thats really all octane booster is, but in a little bottle so that make mad money off nothing

You can also go buy 100 octane race gas


you can run 10 11 psi on that before hitting fuel cut. Then you will need to get this thing called a fuel cut defenser or a Vein pressure converter HKS makes them. I would go more for the vpc, and a apexi afc. Do the intercooler and all hard pipes, a fuel pump and crank the boost to 15 16psi (some people have ran more but its out of the efficency range supositly but times talk at the track) Get a 3 inch inlet turbo muffler off ebay, and get a exhaust shop to do a 3 inch exhaust with minimum bends. Get a good downpipe, and she will rip. Head gaskets are stupid on those cars, so that might be in due.

My buddy did a ebay super t70 turbo kit on his mk3, on 16psi the car went 13.0@118 on street tires spinning though 3rd!
