She lives
Cold start up showed about 75~77psi of oil pressure, and after it warmed up, it dropped to around 25psi.
Kinda studders at 1K rpm (haven't raised the base idle yet), but it idles solid, doesn't try to die on me. Revs freely, doesn't really hesitate. Went with the Nismo thermostat, and 16psi rad cap, coolant is about 80% distilled water, about 10% coolant/antifreeze (don't know why I put it in), and about 10% water wetter.
Only leak is from the oil feed line banjo bolt on the block. I tightented it down as much as I could get it, but it still seems to have a small leak. I'm going to try and tighten it again, and if I can't get it anymore, I'll end up just replacing the banjo bolt and fitting.
Next step is to get her inspected and registered!
