You would have to build your motor to even run 10 lbs. And the motors are different. The ITR motor has more compression, different cams, and I think the intake porting is a little bigger. You could probably run 7lbs around town and if you wanted to bump it up to race, you might be able to get it at 11lbs. I wouldn't recomend it without a thicker head gasket, and hondata ecu. I would want my fuel curve to be exact if I was going with that kind of boost. You should look into the turbo's alot more if you are thinking of doing this.
