i have a high compression motor right now...it's about 12:1...i was thinking about getting the .072" cometic HG to lower the compression...should i get the HG and turbo my car with a gt30r, or should i keep my cams(BC4), keep my compression, and squeeze a DP 100 shot on it?...the car is not necessarily a daily driver, but it will be driven alot(2-3 times a week)...let me know.

 

hmm...i say spray on it....I know people have turbo'ed motors with compression that high, but it's not worth it IMO....Or just get new pistons and sell your old ones.

 

new pistons and turbo

 

I agree
