My friend just swapped a b18c in his DX hatch, and seeing how I already picked up a y8 manifold and JG 310x cam. I was wondering how much of an increase in compression would i see by using my d16a6 head on a d16y7 block. My a6 block has real good numbers (forgot um), but I would rather use the d16y7 because of its lower miles.

 

it would lower it by 1 point so if its at 9:1 now id be at 8:1 larger combustion chamber

 

oh ok. Thanks For the info.

 

Perfect for a Turbo... man, that motor would scream!

 

i have heard of guys (dont know if its true) using the a6 block with the y7 head...would this work???? how is it done??? you just plug an oil squirter and use a stock head gasket.... nothing else????

 

<<<<has a d15b1 block with a y7 head same head as a z6 with no vtec no modifcations needed it gives higher compression #s with the older d series motor i like it but still cant wait to get the b16 in and **** few more months
