Re: vtec or non-vtec...
if your going to do ls/vtec(ls bottom end with a vtec head)
build it right with pr3 pistons,supposing you have a obd0 car and get arp rods bolts,and the eagle ls/vtec conversion.doing it properly will make your motor last which unlike mine didnt even get me home without throwing a rod through the block
and yes vtec owns all
