d16a1 pistons
I have read the the D16a1 pistons raise the compression on the y8 to 12.6 to 1. Whats compression does the y8 have stock, and what kind of improvements can i expect? ( in therms of HP ) Also will i need to upgrade anything elese when doing this, like the fuel system?

uhhh 12.6:1? i highly doubt that much compression out of stock pistons

Re: d16a1 pistons (cambopheonix56)
quote--The 1988-1989 D16A1 Engine came with some really high dome pistons, they will increase your compression ratio as follows:
d16a1 pistons (stock bore) in the following with a y8/z6 metal head gasket (no mill):
d16a6= 11.0: 1 compression
d16z6= 12.0: 1 compression
d16y8= 12.6: 1 compression
- end quote
