all: I just got back from the shop. All of the coolant lines are straight. I officially have no idea what's wrong with this bucket. I'm going to be paying someone to figure it out when funds allow it. There's a local shop that specializes in swapping motors that the Honda dealer reccommended that I call. My local Honda stealership's service manager said there's no way to log this ECU or the sensors except for grounding the ECU pins, so they couldn't do any diagnostics I haven't already done. They said they can only log '96+ cars.
qtiger: I already did. I did this by attaching a turbo boost leak tester to the throttle body inlet, crammed bolts in all of the vacuum lines (brake booster, fuel pressure regulator, pcv hose, idle purge solenoid) and pressurized the intake after spraying every square inch of the throttle body and manifold down with soapy water and checking for bubbles. Surprisingly, it held 10 PSI with no issues or bubbles whatsoever. It took about 10-15 seconds to leak back down to zero (normal, because the rings don't make a 100% perfect seal, and it hasn't run long enough for them to fully seat, either). If there were even a tiny leak, It would have foamed up where the leak is.

The one I made is a lot nicer than the one in that post. I have a 60 PSI pressure gauge on mine. it's really a tool for turbo cars, but since the throttle body inlet was basically the same size as the turbo inlet on my GSX, it worked just fine. This allowed me to test ALL the gaskets on the intake side exactly as they were, and without using caustic cleaners (like carb cleaner or ether) as a fuel source that would eat the fresh paint off of my manifold. I never thought I'd be using it on a NA car.
I will post a follow-up when I finally get something done about this. Money is tight right now as I blew it all on the swap. It will be hard to save money driving the GSX while gas prices are the way they are. I hope that whatever I spend on diagnosing the Civic helps someone else out someday.
