These are not update pics. These are just random pics that I posted up that are not completed. The manifold does weigh more than the stock porus cast ones. If you look inside the stock one, the plenum volume is very small and it is mostly runner length. With 2” short runners, the floor of the plenum sits low thus allowing a bigger plenum. If you read my above post, my turbo application will actually have the stacks sitting on the floor of the plenum which is where it belongs. I have already taken into account the sealing issues, vacuum ports,etc. The manifold fits gen I-III. People have bolted on a gen III on a gen II before. It’s the same bolt pattern. This is a track car only so I am looking for the biggest tb I can get. If you read my earlier post, the bolt has already been taken into account when putting the manifold on. The cnc machine as already tapped and threaded the opening on the runner and stack for easy screw on. The machine does it all with programmed commands. If you call up any alloy company, with a thick aluminum block of 4” thick for the bottom part, the aluminum only comes in 5052 grade. The company sells treated AL and it is certified. But for my purposes, I wished they had non treated AL if it is cheaper because it does not matter. The o-ring design is actually incorporated on the top piece. The fuel rails have a screw that goes through the bottom of it and actually attaches to the top piece. I try not the put to many add ons to the bottom piece because it is expensive if you mess up on it. I rather mess up a smaller less expensive top piece of aluminum than try to put all the fancy features on the big piece and end up messing it up. The injectors stand vertical. Sometimes it is hard to tell on clearance issues on a pic but on a cnc machine, it is dead accurate on measurements. We’ll just see how it all works out and what the issues are..
