im almost done building my 1st ls/vtec. i was wondering what the PSI per cylinder should be when i do my compression check. also what compression ratio should it be at....its just a stock b18b with a b16a2 head on it. Also i have a set of ITR pistons or B16A pistons lying around since the head hasnt been placed on the block yet would it be worth it to put either one of these sets on the LS rods? i just dont know what to expect from a stock LS/VTEC combo since im used to driving my b18c1 and I think im going to be dissapointed with this set-up. all help is appreciated.
