I have a B16a2 (00 si) Head and a B18a1 block. Do I have to change the pistons? Will the B16a2 pistons work if I have to change them? Thanks for all your help in advance.

Please don't tell me to search because I did and did not find what I needed.

 

the b16 pistons can be refered to as PR3 that will help your search.. a lot of people use these pistons in LSvtec because it gives you a higher CR than the LS pistons.. they are usable without modifications if im thinking correctly.. but search for PR3 pistons or something and u will find it make sure u search in archived and recent
