I know this is a very bland, and straight forward question, but what is an acceptable size piping diameter used for a Turbo manifold on the K20Z3?
Yes, my fabricator wanted to know the best size to use on these motors.hmmm, im not too sure. are you going to be welding it yourself? If so its suggest considering a twin scroll sidewinder but i dont have much experience with these motors just yet. its definitely do-able though
