    Ok so i dont knwo if anyone is familiar with SolBlu's Helpful Del Sol Site site. The D-series compression calculator, and i use it alot to mess around for future piston/block/head combo's. Well the way my motor is set up i have 8.1 compression. Alot lower then i though i would have from my Vitara's, i was told it was 8.6:1cp. Well i want to get new pistons to up the CP to around 10:1. It's telling me that with d15b7 pistons i will have a 10.1:1 compression.. Can you put d15 pistons in a ZC??!??! I have no clue, and i thought you couldnt. Otherwise my only option would be D16A6 (PM6's) which would put me at about 9.5cp. What you guys think?

    You can put D15 pistons into a ZC. The bore is the same. Pay attention to your compression height and make sure that the piston doesn't stick up past the deck.

    The compression hieght of those pistons is 61.76, and my piston to deck height is .040". That work? :huh:
