Someone please help me figure out my compression...
I'm building an 84.5mm B20VTEC.
B20B Block
LS/B20 Rods
LS/B20 Crank
84.5mm RS ITR pistons
3 layer OEM headgasket
Supertech flat "race" valves
GSR head which has ported/polished will flow right around 280-285cfm
Can anyone help? I've heard numbers all the way from 11:1 to 13:1, I just really wanna know.
