#212294 let me first start off with a disclaimer by saying that i am not responsible if you f$%k up your motor cause you did something wrong but here are some general d15 series builds for n/a :thumb:
and im not 100% sure that all these piston head combos will work lol

say you have a d15 block heres your options :

d15b/7/2/8 block
piston options are few
basically you can only put d16a1 pistons in a d15 block compression will be 9.26 to 1 with those pistons and they will sit below the deck .030 thats with a d15b7/ d16a6 head
i have thoght about this build and i think you could deck the block .030 and have a sweet high compression d15b7 compression would be 9.92 to 1 with a b7/a6 head if you used a z6 head you would have 10.7 to 1 and thats all using a b7 head gasket if you used a z6 hg it would be 11.04 to 1
in conclusion
b7 block a1 pistons deck block .030 use z6 head z6 hg 11 to 1 compression
b7 block a1 pistons deck block .030 use b7/a6 head use b7 hg 9.9 to 1
b7 block a1 pistons use b7 head and head gasket 9.2 to 1

b7 block with b7 pistons use z6 head and z6 head gasket (mini me swap) 10.2 to 1 compression
b7 block with b7 pistons use y8 head (also a mini me swap) z6 head gasket 10.6 to 1
b7 block a1 pistons use y8 head and z6 head gasket 10.6 to 1
b7 block a1 pistons deck block .030 use y8 head and z6 head gasket 11.5 to 1 not sure if thats even been done but it would be sick for a d15 n/a
b7 block b7 pistons with a d15z1 head and a b7 head gasket 12.5 to 1

:shock: thats crazy
somone should try that lol

well thats it for the b7/8/2 block lots of options there not sure they have all been done or possible but those are the numbers :thumb:


also if anyone has done any of these swaps let me know and post up here
