This turbo "kit" is based on the "ebay" t3/t4 manifold. I reinforced the weak points and braced it to the block. The DP required signifigant modification to make it work right. Although I am happy with the results, I can't recommend this path for everyone as the modifications required to make it all work are extensive. If you are considering piecing together your own turbo kit, you would be better off buying a hafe manifold and o2 housing and use your own DP or perhaps just a FP green. This is a journal bearing PTE 50 trim. This is with HKS 264/272 cams, regular supporting mods. All told I have less than $4,000 into the mods which includes CP pistons, and eagle rods. The tune was on the conservative side at 29 PSI and 11.8:1 AFR This was on a dynopak dyno. The car is a beast and a blast to drive. This map was on c16. pump and meth was about 40WHP lower.
