Can anybody tell me if the B18A and B18B intake manifolds are the same or at least compatible enough to be interchangeable? My friend has a 90 LS Integra with a nice big hole in the block and he's just going to part it out instead of putting a new motor in it. Anyways, I am wondering if his header will fit on my 97 LS coupe. If so I'm definetely going to buy it from him because it's a barely used DC header for dirt cheap.
 
itll bolt to the head, im just not 100% positive itll bolt to your cat.

i dont think it does actually bolt to the cat.

Yeah that's what I was thinking the problem would be, cuz most B-series headers are interchangeable as far as bolting up to the motors right?
 
yeah, the header bolt pattern is the same.
