Hey guys i finally started my VR4 after it being off the road for over a year.

While it was off the road I completely rebuilt the motor, gearbox and front transfer case.  

For the first startup I hooked up a mechanical oil pressure gauge to the oil sensor hole on the oil pump housing and found my oil pressure to be really low and to not be consistent at all. moving around 30-10psi constantly. I changed the oil filter yesterday and found that the issue with fluctuating pressure to be gone but on cold startup I still only had about 70psi. and when it got warm it dropped down to about 20 sometimes down to 15psi when revving then letting it idle. As soon as I rev the engine the pressure builds quite nicely. I haven't gotten my tacho hooked up yet but I'm guessing around 60psi at under 3k rpm.

I've been told this sounds low I'm just not sure how low. It's a brand new oil pump and i have done the balance shaft delete.
