me and my buddy are building a 84 carpi and we just got our new t3/t4 turbo. the t3 on the car was cracked and we picked a t3/t4 to replace it. where not sure what typ of wastegate to go with . we want to run around 20 psi should we go with a external wastegate. if we should can any of you guys/girls explain how to install one.
where both new to the turbo game.
