I HAVE A CRX WITH B16A , BUT I HAVE USDM ITR PISTONS ON IT! I NEED TO KNOW WICH PISTON WILL MAKE MORE POWER...(PR3 OR P30)
I RAN 14.00 IN 1/4, BUT I WANT TO KNOW IF I CHANGE THE PISTONS FOR A PR3 OR P30 WILL RUN LOWEST TIMES???

 

theres really not a big difference between those pistons. the jdm b16 pistons are 10.4:1 compression and the usdm b16 pistons are 10.2:1. get some ctr pistons and boost that compression up to 11, then youll see some real results.

they are either 10.4 or 10.2 so there is a mild difference in power that you are going to get.

 

WHAT I NEED TO PUT IN CTR PISTONS ON B16A...ANY MODIFICATION TO THE HEAD OR WHAT????
LET ME KNOW I'M VERY INTEREST!!!!!

 

like i said, as long as you have good fuel management to handle the high compression, you can put ctr's in a b16 with no problem. good power gains.

i already went through two sets because of running too lean, so make sure you get it tuned.
