I have a d15b2 engine with 210000 miles on it and it was running but i pulled it and tore it apart for an upgrade and boost. The engine was pretty clean looking very well maintained. My question is I want to put in some teg rods and pistons for higher compression and beefed up rods. I know that can fit but what if i throw on the y8 or z6 head for vtec mini me effect how is this going to work out. I know my compression will be very high will it be too high for low boost like 5-8 psi? Thanks
