I have been building d16z6 engines for a car racing circle track and at a loss to find more power. I read some info about using ZC internals and currently have the ZC crank, rods and pistons in my Z6 but the power seems to be the same as a stock Z6. Any suggestions for some extra power would be great, thanks!

 

Boost.

lol at the ZC (echos zc a few times) there are 4 types of "ZC" motors 2 with vtec/ 2 without. figure out which one you have first. then the "ZC" pistons you are referring to are those from the 87-89 integras AKA p29's or pm7s (high compression) - because they have a higher dome height. the pm7s and p29s are slightly different also but do the same thing raise compression
