Zc are okay, but if you are gonna boost anything. Better be less than 7 psi, cause they have small ass rods. But on the good side, you can still us the same mounts and tranny. You could put a JDM zc in for less than say 600 tops. That would give like 130 something and boost just 5 psi could be like another 40 or so hp depending on the set up. IT ALL COMES DOWN TO MONEY
