posted in this post below, please let me know if this combination of porting and the 1.5 turns clipped off the spring is too excessive or about right or even not enough so i cna get my car back together please

I've heard ths stock spring opens at 78psi, so by clipping this have i maybe lowered it too much for the engine at high RPM?

I'm just trying to get things from being at 100psi when i've above 5k RPM, i don't want to lower oil pressure so much it's dangerous

Looks fine to me.

The difference being the stock pressure regulator is gauged to handle an amount of volume from the stock oiling system. Remove balance shafts and the pressure goes up, possibly more than the stock regulator can handle. Modifications are then necessary.

Lower peak pressure benefits more than just the turbo. When high-pressure oil is blasted into a tight tolerance under load, it tends to burn away and vaporize rather than lubricate. This can cause excessive oil temps resulting in unwanted bearing wear.
