the intake might fit if the tube is the same size and you can make it slide on the throttle body (i think it is going to be too long, and at the wrong angle) , the exhaust from the cat back will fit if you get the excess piping cut off or added as the case maybe (depends on the b18c motor you get 1 or 5). the exhaust manifold is of a totally different bolt patteren, plus a b series motor sits differently in the motor bay. also the colector pipe to the cat, bends too fast and will be either too short or too long in some areas (if you plan on trying to keep that stuff). personaly i would swap, get a header, and get custom exhaust piping from the cat. to the first junction in the exhaust system (were the piping bolts together to go over the suspension).
