ok so i know the basic of going turbo..but what is confusing me is the wastegate part..so here goes 1.are wastegates universal??im getting a kit,but it needs downpipe and wastegate,the manifold is obviously for an external.. 2.say im going to boost 8psi-what determines the 8psi??is it the spring in the wastegate??and with that being said,if im boosting 8psi do i get an 8lb spring? 3.tuning-everyone says get it tuned,my car is obd-0 and im not converting to obd1 for awhile,,so what do i do??
