Just wondering if you could do a B20/VTEC with the B20's out of an 89 prelude. This kid (he's a friend, of a friend's, friend...hope that made sense. Anyway...) wants to either do a swap because the motor is blown or go VTEC using his existing block. I've put together quite a few motors so i'm not an idiot, but I can't, for the life of me, find any info on using the B20A block or swapping in a GSR or some shit into his Prelude. I hear rumors that the block is not usable for going VTEC so i'm looking for the answeres as to why. Also, could I just put a B20B or Z into this car if going VTEC is a no no?
