Since the oil pump has to come off is it better to run balance shafts or take em off on a daily driver?

It's up to you, but I would keep them on a daily. Stay on top of changing the belt. Even double check balance shaft belt tension at 30k.

I read that if your running aftermarket forged pistons there's no need for the oil jets.

Look at the clearances in the bearings and in the oil pump. A bandaid fix is not the right way to go.

Your issue is not due to oil jets. You need to find the actual issue.



You either have an issue with your oil pump/pick up. Or you did the balance shaft delete without rolling the bearing. It's not likely, but you could have WAY to much side clearance on the rods. Although, I don't think that would cause this drastic of an issue.

That is bad internet advice. If people think there is no need to cool the piston in a forced induction engine, let them deal with that.

No body has asked what weight oil your using? If you are looking to bump pressure to a degree without taking things apart or deleting them---although you should find the problem first-- put in the Kiggly restrictor in the head. its a bolt up and even hot I am at 22lbs at idle @ 850rpm. Which is more that stock. Stock I was at 7-10lbs hot at same idle, I assume you were as well when the motor was running... I am not etirley sure you have a problem at 13lbs

The issue is the oil pressure dropping when he goes from idle to 1500rpm. That should definitely not happen.
