528 M20B25 on E30
I have putted M20B25 engine in my e30 and I have some questions, think you can tell me, in 24 December in my country is championship in drag racing, so whats why I do this, and I need to know in which pressure I must put in my wheels, 2.0; 2,3; ,2,5 ? also witch size i must take 225/50 or 225/40 ?
After tires get warm/hot run them as low as possible for maximum traction. As far as tires, bring both sizes mentioned and experiment. If tracks there are like here, they'll change round to round with build-up & heat. (There's no written rule of success - it's ALWAYS experiment and go by experience & feel) - good luck
