I have a '91 civic DX and I've been looking at many swaps, specifically b20/vtec. It's finally gotten through my head that this may be too expensive, although it can be done. I'm opening up to other possibilities like a Mini me coversion. All I would need is the head seeing as My cars got the bottom end. However this is all I know about the swap, so If any body knows where I can find a guide or can tell me more than I already know.......
