Ok im building a z6 boosted, wanting to run 20lbs of boost and right around 300whp. I know what internals im using but im kinda lost on the ignition, fuel system, and drivetrain(clutch and axles)? Im not trying to do it cheap and i want to do it right. If anyone has suggestions please give me some advice. Also i have herad i dont need to sleeve or gurtole my block? Should I?
