ok Iv got the f22a weak 125hp ok ... if I swap the vtec head over from a f22b and the ecu to use the vtec. what else will I have to run due to obd0 and obd1 . Also I was told I dont have to mod anything unlike the vtec swap on a b motor! Is this ture. Do I run a new oil line and all that? Or dose it bolt strait up no mods??
