Look in the classifieds under stealthmode's for sale thread for a pic of the ball valve. To monitor the oil pressure you will need a gauge. This way you know how much you are adjusting and too much oil will cause oil to pass through the seals.

 

I bought a -4 an braided steel oil line, same as the ones that come in the kits. Will that work? hope so, the sob was expensive.

 

The male and female sides of this valve are 1/8npt, but they can be ordered in other sizes as well.

 

nice stealthmode i have hade a couple of thoughs laying around but they are 3/8 used a 3/8 ss hose from lowes and added a inlet screw on needle valve, what ever size is cool as long as you can control it, hey i had someone tell me to regulate oil pressure after the the turbo on the drain side that wouldnt be wise right?
