Well, it took a while, but I finished yesterday, just in time for the differential bearing to go out on my other car.

Drove the GP about 100 miles or so yesterday, no problems, no visible leaks.
Yes, it took too long, but my time is limited, and this was my first time working on one of these cars. So a lot of time was spent googling how to disconnect this or that plastic part without breaking it, finding other stuff that needed doing while it was off, ordering parts and waiting for them, driving around to find tools and other parts, all while trying to keep my job/girlfriend/kids from feeling neglected.
So the "extra" stuff I did, as best as I can remember...
- In general, lots of cleaning up of parts, cleaning gasket surfaces, etc., maybe more than necessary but I had time
- Repaired exposed wires in the harness to the PCM in the airbox (spliced/soldered/heatshrinked individual wires and re-wrapped whole thing in electrical tape)
- Modded the LIM, hogged out the side coolant passage, blocked TB coolant ports, per BillBoost37's howto (Fastenal had the plugs locally, if anybody needs a source.)
- Disassembled supercharger/throttle body, inspected/cleaned, regreased needle bearings, replaced coupler, TB gasket (spent a bit of time playing with this stuff to understand how the SC works)
- Finding valve covers were leaking, finding inner lip of one was chewed up, eventually just used a little extra sealant in that area, no leaks but I have replacement covers now if it starts again
- Cleaned up fuel injectors, replaced filters and o-rings
- Trying to repair crumbled vacuum harness tee, got engine running with standard vac line/fittings, but next day bit the bullet and bought the expensive dealer part to avoid future headaches
- After it was all together, finding the one fuel injector I'd been getting codes for, still got codes on the adjacent cylinder I'd swapped it to, so ordering replacements and swapping one in
I don't know how long this whole job would take me now that I'm basically familiar with all the parts, but replacing the bad injector took probably under an hour (didn't time it.)
Thanks for all the help along the way! Next comes the transmission (4th gear clutch hub) but I'm gonna drive a while before I get to that. Most of my driving is under 45mph anyway.
