Oil pressure is normal, carry on. The 4g63 notoriously does not follow the old 10psi per 1k rpm rule.

I haven't check at wot. I drove it around the block since it has to plates.

Letsgetthisdone quick question for you on setup.
How many psi are you running and any internal work to the engine?

Everything that would effect oil pressure is stock. 15w50 oil is 20-25psi hot idle at 1050-1100rpm. 3800-4000rpm is like 80-85psi.

I was asking about your engine setup.
What psi of boost are you running to make the 500+ whp that your making.
I'm shutting for above 500 whp with a hx40 turbo with my setup and just wanted to know what boost your running.
