i have a gtp38 off a ford diesel and im wanting to put it on my 1jz but im looking to drift it so i cant have to much turbo lag ive been reading that the rx7s do this swap. the hot side a/r is .84 which concerns me but also it has a 1.10 cold side a/r and also should i upgrade the injectors to the 2jz ones im only lookin to do maybe 15psi for now .
