i also just finished this manifold that u see below for a guy by the name of Mark Bullett who currently owns the fastest and most powerful non turbo eclipse. he was running a ported stocker for the longest time and then he recently bolted on an obx POS after doing a quite a bit of modding to get it work its best and picked up a whopping 3 whp i believe it was. anyways he came to me to see if i could modify the stocker cause ive been doing it with neons for a few years now and heres what i came up with..........
what u guys think?

I think it looks very nice.
Considering OBX is such a piece of **** im suprised it made any power at all. I guess that shows just how restrictive the stocker was.
Good work!

remember he had to do i bit of mods to get it to where he wanted it before install........... like he had to port the match the flange to the runners because there was a huge step that was going to cause lots of turbulance going into the head, he also had to grind down the 1/4" lip where the runners protrudedabove the plenum floor and then1 other thing i believe. dont get me wrong im not giving the obx any credit what so ever i think its a POS.
