i am going to use a b15z1 block out of a 93 civic i want different pistons i was looking into the pm3 flat topped pistons i was wondering if this would work with a y8 head i was planning on using pm3 pistons on stock d15z1 rods.... would this work??? the deck of the block was resurf. at .007 im going to use a standard size head gasket please let me know????

pm3 pistons are too tall and will stick out of your block by 3mm.(30mm piston height) the only pistons you can use is those that are about 27mm such as the stock vx pistons, jdm D15B pistons, or stock GX pistons from 2001+. this will put your compression from stock, 9.6, and 10.8 respectively.

how about pistons out of a 99 civic the same motor i got the y8 head from??? would those work i have them brand new with rings.....? i forgot the name of them please let me know asap??? or how about p28 pistons???

you have to remember these are going in a shorter block. theres a difference in the deck height from the 1.5 blocks and the 1.6 blocks. but the d15z1(vx) block is a little tricky which wont let the dx or any other pistons in there...

no the y8 pistons wont fit unless your willing to do ALOT of work to get it...which imho isnt worth it. id order new PMS pistons from a 2001 civic gx from your local honda dealership. new pistons pins and rings should be about 300.

ok will this help my performance wise???

could be a combination of outside factors, but my 1/4 mile time dropped from a 15.0 to a 14.5...you will feel a difference.
