PHILLYSUPRA said:i honestly don't see why you couldn't use the n/a manifold. the valve in the middle of it is just toyota's ACIS valve (acoustical control induction system) it just gives the ge model more torque by simulatind longer and shorter intake runners. (search mkiiitech.com) you could just simply figure out how to take that valve out and plug the vaccum port it's connected to. i got two extra n/a manifolds lying in my basement right now that i was gonna use for extensive porting experiments, but i think i'll give it a try myself.
The design of the N/A manifold would require a lot of modification and porting to essenctially remove all of the area around that valve as well because it is like a divider between the two and with a single end being fed all of that has to be removed. I have an N/A manifold but it will probably end up as the first one off donar, as the runners are the same. More power to you if you think you would be able to make it work with my setup. Just does not seem worth the time, unless the person wants to pay for all the work it will take to get it just to what a turbo manifold is stock. But I will do them. Hope this helps.
