Ok I have this engine that came off a JDM 300zx TT and what I would like to know is that do I just change the upper plenum and put my TT plenum on it? because the brake boost is on the other side on a JDM 300zx..so the place where the hose is attached to will be on the other side of the motor if I just drop in the engine without changing the plenum, if it makes sense?
