Thanks...any idea what the high comp you ca nrun with 94 octane....the highest that I've gone with a build was 11.2:1

 

The reason I ask is that I can get a b16b (CTR) head with port n polish, 5 angle valve job, ported intake manifold, bored TB, ctr cams and valvtrain, new valve seals and had .25mm oversize piston before...I can also get the ctr trany with modified final drive!! If i put that on a b18b block with ctr pistons +.25 my comp is like 12.39:1....don't know if 94 oct will do????

 

This topic has been covered extensivly in the all-motor thread. There is a large sticky thread in that room which gives the correct calculations. Ominman wrote a nice post on this in that thread,

 

When I do my search I always go through the Intgra forum...for some reason I never thaught of trying all-motor!!! Thanks I feel like a dumbass but I will then search
