hey guys. i just did a z6 swap in my eg hatch. tossed a d15b cam in that i had laying around. and i still have the d15b intake manifold layin around. i remember reading the d15b intake manifold is a different casting than that of the z6, but i cant find that, so if i were to toss the d15b mani on, would i see a noticable power gain? thanks in advance

If its a JDM OBD1 D15B Vtec manifold its identical to the Z6 manifold other than its already setup for the evap purge solenoid. (the JDM manifolds have the provisions to mount one but require a couple of holes be drilled and one tapped) If its a D15B7, D15B8 or D15Z1 manifold its more restrictive than what you have on now. In either case there is absolutely no benefit to be had from swapping the IM.
