4afe camshaft swap ??????????????!!!???
Hey how goes it with ye all.. got a good question for som1 out there in the know!! i have a 4afe sr corolla 1.6.. soon it will have a blacktop motor fitted im saving/sourcing for parts at the moment.. but currently im wondering is the an interchangeable camshaft for my 4afe from other a series motors, maybe a 5/7afe.. ive trolled the web for specs on each engines camshaft and cant find any and got frustrated and came here!! lol !! . what im saying is if there was a cam from either motors that would fit into my 4a that had more lift and duration and was worth doing i would. surely there must be a difference in profiles between them and lift also.. please people if ye know let me know. IF there is a better cam between them i will fit it.. as im bored and i want to get the spanners goin some before i do the blacktop swap.. also IF there is a better cam i will stick a 7afe head gasket on to raise comp. maybe a head skim and a little home polish job nothing deep just a cleanup.. all in all in my mind if all three were done - cam,thinner gasket and MINOR head work its got to add up to a few more ponies.. BUT unless i can be 100% certain on the camshaft scenario im not putting a spanner near it till it swap time.. OR if som1 can reply and give me exact lift and duration of all three engines camshafts i.e - the 4a/5a and 7a i will come to a conclusion of my own. maybe a lot to ask for but fence sitters get nowhere. thanks if youv'e read this and muchos gracias if you can answer.
