I was jus wonderin what is it that i would need to swap my f22non vtec to an f20 b vtec? Do i need to swap the trans too? And headers too?

 

Welcome. You're going to need the wiring harness as your non-vtec engine doesn't support the vtec system, same applies to the ECU.You'll probably find your existing trans will need to be replaced too, due to the gearing in it (it's an economy trans with highway gearing. Look on e-bay for a header. I've heard an "H" series header will fit with minor mods. You'll probably have to change/fabricate some engine mounts as well. Over on 6th gen Accords, a guy over there did put in a F20B into his Accord, but he used an "H" series trans.He also fabbed up new motor mounts, redid his wiring, and went with a different ECU, to get it to run correctly.
I hope this helps.
