I've searched but really haven't gotten any answers. I have a 93 Integra Ls and am eventually going to go Ls/Vtec(my brother lives in Japan and I can get the parts somewhat cheap. He doesn't know too much about this cause he has a 180sx). I want to start getting the parts now and was wondering which b18c5 parts will fit a b18a. I read that the headers fit but hang low so I can just put a skidplate on. Is this true? What other parts will fit. I don't have enough cash to get all the parts at once and can't wait for more power so I was just going to get some of the parts and install them now. Is this even a good idea or should I just wait for the whole setup? What else can I get for the b18a that will not be obselete w/ the Ls/Vtec? Thanks in advance for any answers I'm still trying to learn.
