I like to measure oil pressure as close to the main galley as possible, which will warn of restriction in the filter and cooler.

If you're measuring it pre-filter/cooler, there there may be a restriction somewhere in that flow path causing the high reading.

Mobil 1 5w-30 should be fine for a tight clearance motor.

Good luck.

Now that I have some time I logged the oil pressure when I took the car out for a drive. Cold idle I am at 95-105psi (45-55 degrees) and once the engine is warmed up I am seeing 35-45psi (165-175 degrees). That all seems very normal to me. During a pull up to about 6k RPM I am seeing just shy of 125psi. From the reading I have been doing I don't think that too out of the norm. Thoughts?

125 psi seems awfully high but I dont have any experience the JZ motors.  Most race LS and SBC are max 80-90 psi with cold idle near 60 psi

That seems high if the oil was up to temp. Was the oil up to temp? What weight oil are you using?

your pressures sound about right for a JZ and are close to what mine are when hot and throughout the RPMs. I am taking my reading from a sandwich plate between the block and oil filter and running mobil1 10W-30. Some good reading in this link about JZ oil pressures. https://www.powerhouseracing.com/topic/oilpressure

I am running Modil 1 5w30. I, too, read that information from Powerhouse Racing which is why I did not concern myself with it. I was going to swap back from dual oil coolers to the OEM cooler to see if this would change anything, but not sure I want to go through all that.

Turbo Update: I have decided to change turbos. This S363 is a lag monster! I do have the larger (80/73mm .83a/r divided housing) exhaust wheel as I had this turbo on my 13B. I was not seeing 15psi (gate pressure) in boost in first gear and would not see it until just under 6k in all other gears. I bought a Garrett GTW3684JB. It has the same specs as a Precision 6262 with the reliability for a Garrett. I opted for the .70 divided housing so that should drastically help my spool up. I will post up logs of both as a comparison once I have the turbo installed.

The S363 will be great on a 2JZ, so it will be up for sale shortly.

New Update:

I have been driving the car for a while and have been less than happy with the spool time of the S363. I am not seeing 15psi until around 6k RPM, and not at all in first gear. I decided to go with a smaller turbo that would give me more throttle response and still get 550 wheel out of.

Went with a Garrett GTW3684 which is Garrett's version of the Percision 6262. The smaller frame of the turbo is great. It fits way better. I will some day remake my downpipe using 3.5" pipe and have it turn down much more gradually.

I have not had a chance to powder coat the compressor housing but I quite a bit happier with the power band. It still seems slow to spool so I need to do some additional digging but I am now seeing 15psi by 5k RPM.

Here are some photos for your enjoyment.

Can you get do anything with timing to help the spool?

I am planning to take it back to Sound Performance to get the tune finished at some point this summer. I want to get some additional miles on the car to see if I can break anything else.

I am surprised to hear you had such trouble spooling that S363 and your new turbo setup. I am hitting 18PSI at 3750RPM when stomping on it at 2000RPM with an S362SXE. It is pretty responsive when im sitting at 3K and go WOT too. I didnt think that 2.5L compared to a 3.0L would affect spool that much. Was this an SXE S363 or the last gen FMW airwerks turbo? how is the build doing, did you ever get it retuned? Nice car BTW!
