Update...
I was so sure I was going to turn the key tonight, worked from 6pm until midnight, only to learn that my lower heater hose was leaking out of the back of the engine. The JDM block has it on the opposite side from the USDM block (some LHD/RHD thing), so I thought I could use just any hose I had lying around... 3/4" appears to be too big, time to pick up some 5/8" tommorow. Then... I can drive like a granny until I'm sure the motor is ok and my clutch is broken in
