    With the inlet manifold and throttle body fitted increases of 20bhp have been claimed, A remap would be a good idea as you would get the full potential of the mod

    Manifold only! keep your old m52 TB
    it could give you approx 20 hp remap does help and is suposed to get back any torque loss in the mid range

    i doubt you would see any bhp increase at all tbh and if you did you would be lucky.
    the only way you would get any bhp increase is if you taper the inlets on the head

    No the E36 325 manifold fits onto the E36 323/328 and unrestricts the motor for approx 20hp

    yes

    all 323/328 are restricted with small intake runners the m50 325 manifold reverts it back to where it should be
