I recently revived my fx corolla swapping a redtop 4age into it, the original motor was a 5a-fhe 1500cc. I was wondering if there will be any issues getting a wof?, i know that these cars came out with 4ages and i think the power dfifference is only like 15hp (Also drives much the same), even bolted onto factory g/box, Will i need a cert or is it alg?
