Just went through your thread, and I have to say, that is one nice Supra! I've also combated a BHG and RK in the same order and just got mine running too. My oil pressure gauge rested at the same place, sometimes lower, but when I put a mechanical gauge directly in the port I was getting around 18 psi at idle and I have a new OEM pump shimmed 4mm with a non-shimmed filter housing too. I'm hearing a tapping noise from the engine, but listening to your videos and some others it seems Supras just normally do it.... I think.
