Manifold and sensors installation
I decided to use my aluminum air box , but did not want to cut up the fuel distributor section since this air box is rare. Instead, I put a flat sheet of steel in the location where the fuel distributor would have gone to cover the hole and serve as a mounting surface. I used the plate to mount the MAP, FPR, and IACV.
After scratching my head for a while on how to route the IACV, it occurred to me that I already had the right size piping from the CIS AAR system. Using the old Auxiliary Air Regulator adaptor and piping, I cut it up to connect the IACV back through the adapter for the Cold Start Valve and sealed the Cold Start Valve hole. I just had to cut it up and put the pieces in the correct angles. This worked out well.
While in hindsight I could have mounted the FPR near the top center of the engine bay, I used aluminum angle to mount it on the plate, near the throttle body. I also mounted the MAP sensor using the same aluminum angle. The advantage is that the wiring harness has all of these connectors near the same spot so it worked out well.
Here are pictures of the IACV, MAP, and FPR install.
For normally aspirated, I will put a small filter at inlet to the IACV. When I go back to supercharged, I will put a check valve there as well.
I had to source another throttle body because the rod on the SC throttle body does not extend beyond the body so I could not mount the TPS. I added the Rasant spacer and TPS. After some mods, I got everything in place.
The last question was checking the interference between the supercharger and the fuel rail. I ended up cutting the height of the fuel rail just like on the other side. I will have to reroute the supercharger bypass after sealing the old bypass return at the supercharger to avoid the interference.
The plan is to start playing with the AEM while NA and later add the boost back again.
