ive also tried this exact setup with great success on the 3rd gen rx7, all s13 s14 s15 cars, the ae86 (which is a picky little bastard), the altezza, also HERE's A LITTLE CHALLENGE. make a 1100 hp supra rz. with these exact settings and super soft tires. leave it in 6th gear and drift around your favorite course. if your good enough with the throttle.
if you dont want to do the 6th gear thing put a smaller turbo on
