Is there a rule book on what motor goes in what?? I have a friend getting ready to order his H22... Its going in a 93 civic hatch.... You can put any motor in anything!!! And I am not going to do a B16, I was considering it.... I just couldn't afford to spen 50g's on a stupid motor..... With a H22 you are a little more limited to how much you can spend..... I mean the Import Draggers are putting 150g's + in those motors and they are running B16's B18's... I know how I am If I can have it done or do it to a motor I won't be satisfied until its done, and I don't have the wallet to support a b16..... That would be a dream engine... I agree that the most economical way is the H22 then a little motor work and a S/C and your ready to roll and only about 6g's poorer...
