I have seen that there is a posibility that a M50 Tuebo Manifold will fit the M42 by cutting off runners 1 and 2 and welding the turn on #4 shut. Just want to confirm if this is true or not. Also, does it have to be re drilled? and will a standard 60 trim T3 fit with internal wastegate? I have a 91 318IS that is ready to roll and I want to make that puppy scream.
