There are a heck of a lot of manifolds for the B18, the head flanges are the same from memory (I used what I believe to be an SPI manifold on a B18FT to move the throttle body away from the heater box on my 340) but I wouldn't want to run a different one to the stock, the ECU will have a field day. Not all B18's are single point injection, some were carb (B18KP) as well as the multi point Fenix'd (B18F) and LH'd (B18FT). Stick a picture up of the one you need
