OK guys so I'm actually changing my single to dual so I'm actually wanting to kno what r the best high compression pistons for b20 block I'm wanting to actually trying to hit a good 400+ all motor tuned need some help in trying to see what r the best high compression pistons

 

Its time to go read. High compression pistons is a tiny part of what it takes to make serious NA power. Also, 400 plus is not realistic at all on b series. Don't make any more new threads, read the faq, the forum and search google for b20 vtec info.

 

Church's dyno doe?

OP if you want to make 400whp NA I hope you have some deep pockets, and a great understanding of the K series motor. Or v8's.

 

400? Go turboh.
