I just bought a 1990 civic four door. I have a core z6 bottem end that i am using, the crank is at the machine shop now. Now I was thinking of using d16a6 pistons and a extra d16y8 head that i have. I am thinking this will give me like a 12:1 compression or somewhere there abouts. Now what should i use for a intake, i wanna try to stay with stock parts, even the intake. Then would i need upgraded injectors for such high compression, what about internals forged or not, i dont plan on boosting but it is gonna be my Daily. Do you think the starter will turn over that high of compression. I know that this combo is maybe good for 120 HP or so, but I wanna build a d-series that competes with a b-series. Thanks ahead of time fellas.
