Steam vent done, heater hoses done, and most the intercooler plumbing is completed. Interestingly enough, the steam vent hose is the same part number for the V6 since it attaches roughly in the same position as the V8, so while I was concerned that I didn't have one, it turns out that I did
Mounted the front heat exchanger, I used some flat aluminum stock bent/drilled as needed. Made one new hole into the core support on the passenger side, and was able to re-use existing trans cooler mount holes on the driver side. Drilled one hole into the lower air duct for the hose to come out the passenger side, driver side sneaks in the existing opening under the headlight.
Also got the intercooler pump mounted, I piggy-backed off the large steel siren bracket in the passenger fenderwell area. Still need to wire up a small relay to kick on with ignition, but it is very close to the fuse box so it should be simple.
Here is a crude drawing of my layout
I've gotten the remaining fuel/pcv lines done, modified the intake tube to fit the LSA, and swapped to the card style MAF. Should be ready to start soon.
Inside the car, I wired in what I needed to connect to the shift position sensor on the shift box assembly, and modified a single gauge cup to fit in the front cubby without completely blocking it. Going to double check a few things but I should be able to install the console permanently now, as I shouldn't need to get back in there for anything.
Remaining on the mechanical list
Suspension - Will likely be throwing stock struts back on until I can get the shockworks coilovers.
Exhaust - Need to modify my Magnaflow exhaust. I really like the way it sounded on my 13 so I ordered it again. Of course, it's for a G8 so some modification will be required.
IC reservoir - Should be here Friday
Fuel pump - Need to drop tank to install ZL1 unit. Unsure of flow rating on V6 pump and rather not take a chance, especially since I have one here to install.
Reinstall bumper/headlights/fender liners
Remaining on the electrical list
IC pump wiring
Trace out differences between SS and Caprice front bumper wiring to make headlights and wig-wag function properly. Turn signal circuits I think are the same but there are several differences in the high/low beam circuit, in addition to the flasher module that I want to retain.
