Trying to run some build CR numbers and I'm in need of the cc's for:
USDM STi combustion chamber
STi ver7 spec c and Ver8 (guessing they are the same)

I've searched and always seem to suck at it.

Thanks, Micah

I cc'd a USDM STI 2.5 head at 56.2 cc's. I've only checked the US WRX 2.0 heads, and measured 49.2 cc's from them.

HTH,
Bob

thanks....now just searching for the big port heads
