I bought a 83ZX, i was planning on putting in a KA24DET ( i have a FWD KAT) but now i feel that a L28ET will be enough. My question is a) where can i get rebuild parts from ? Is Arizona Z the only place ? What do i need to run a GT40 or a T66 maybe even a SC61 on my L28. I know i need injectors, fuel pump, etc. Is the OEM turbo header the only option next to a custom header ? I searched and found that no one has exhuast manifolds for the Z Also how well will the stock auto handle 350-450rwhp.
