#335275 Is there any way to boost a high compression built f22? Im talking h23 rods and h22a4 pistons. according to zealautowerks.com its like 11.4:1 compression. But I want to put 10-15 psi to it and put down close to 400 hp. Am I out of my mind or is this possible?

#335282 CR should be ok, but cast pistons are prone to melting above 300whp on pump gas and 400whp-ish on ethanol. Good tuner is a must either way.

#335285 Did you even check too see what your piston to deck height was? Remember a negative number means the piston is above the block

#336027 Decided to scratch the f22. F20B is the way Im going. Its gonna stay all motor for now and boosted later on.

#336028 Any reason why you want the f20 compared to the h23 vtec?

#336029 It has iron sleeves instead of the frm ones that the h series has. And a friend of mine has the swap that I can get really cheap just cuz he went different route.
