While you are waiting for the RTV to set up, take a break or continue on. I would start with the TB and plenum. *If you are relocating your IAC, do that before the TB/Plenum* I did not relocate my IAC so I installed it on the plenum. Put on the CAI and MAF. Hook up/lengthen any connectors that you can at this time.
I had to lengthen my IAC connector and add some wire to the IAT2 sensor pigtail. The IAT2 sensor gets spliced into the existing IAT sensor pigtail. If you have a 01-04 the wires for the IAT are with the MAF harness.
Now you can go back and tighten the bolts on the M112. You should have an engine that looks like this.
Now we can move to the other side. I mounted my coil pack on the case of the M112, I bought the M112 with the mounting bracket with it so I figured I might as well use it. Few nuts and bolts and it was mounted. I still need to get some brake line and make spacers so it sits straight, but it works.
You can mount the boost bypass actuator now. Nothing hard about it, just make sure the arm is touching the stop. You will also see the block off plate I made for the IAT sensor hole that the Cobra's use, and the temporary EGR block off until the one I ordered comes in.
Now you can run your vac lines. Here is a diagram:
The line that runs from the plenum to the firewall, is the line that hooks up directly under the TB on the stock upper. Only 1 nipple on the bypass actuator needs to have a line ran to it, the other is left uncapped.
There is this on the passenger side, 2 lines going to a T with a short piece of hose on it(hooks up behind IAC on stock upper). I just ran a line from the one open end to the nipple on the CAI
With all the vac lines routed, you can now put on the new serpentine belt. Since I used the stock crank pulley and stock 3.65 pulley on the M112, I needed a 119" belt. Add oil to the M112 snout, if you need to. If you havent done so already, replace your throttle cable(99-00's only). Double, triple, quadruple check EVERYTHING.
***** I am not including a fuel pump install write up, so you will have to find one to install the fuel pump **** << *cough* Haynes manual *cough*
If everything is "flanged up", it would now be a good time to reconnect the battery and load up your base line tune. Fire it up and see how she sounds/runs.
