I have heard several times that the dohc zc pistons can be a great way to up the compression of a d16y8. I am wondering if anyone can give me an idea of how much they should/would cost, (or where to look for decent used ones) How hard would it be to replace them on the car? ( I am assuming this is something that could be done in several days with me and a buddy in the garage.) Also, maybe most importantly, even if my compression goes up from 9:61 to ( 10:6 or 12:1, I have heard both with the zc, not sure which is right) how much of a power increase should I expect. Is this something that will give me 15-20 hp, or am I looking at something closer to 5-10? If anyone has any experience of knowledge in this, I would greatly appreciate some help or input.
