i noe this is a honda site and all, but i also know theres alot of honda peeps that jumped ship and sold out to subie and mitsu. but thats neither here nor there, is there a difference in the jdm sti bottom end and the usdm bottom end? i ask this because i ran into a guy who was driving an sti and said he had a jdm bottom end. . . it puzzled me because i dont know any thing about them, and would like to know the difference. i tried searching the net, but its hard to search when you dont know what the hell your looking for. . . haha also asking because we had a fun run, and he couldnt pull away. . .n i thought sti's were alot faster. . . if someone could clear this up, it would be awesome.
