d15b setup questions
so i have a jdm d15b vtec head on a d15z1 block. from what i've researched online this is the equivalent to a jdm d15b motor. also from what i've researched it's basically like having a d15 with z6 internals except the stroke length isn't as long. with all these specs in mind i typed these into a compression calculator switching p29 pistons for the factory ones and a 2 layer y8 headgasket. what shocked me is that the compression was rated at over 16:1 for the compression ratio. this didn't seem realistic to me considering the mini-me guides i've read have recommended p29 pistons to bump up compression but i've never heard of it being that high. what i was wondering is if i can actually use this setup in my car and what the actual compression ratio is.

Re: d15b setup questions
13.3 is insane amount of compression... Thats something thats hard to get even if you tried. Well atleast on a b18.
If it runs, i'd get it tuned, that doesnt seem right.

Re: d15b setup questions
Alrite well I figured in pg6 pistons from a d16a1 and the 2 layer y8 head gasket and that produced a 11.3:1 cr is that more suitable rather than a cr close to 13:1
