FP .020" PURPLE oil filter/restrictor
Answer -
If anyone cares, I called FP and asked about the purple 0.020" restrictor hoping it might be suggested for people burning oil with their bb turbos but they said its for people that have higher than normal oil pressure due to removing balance shafts on 4g63s. Also usually for GTRs for whatever reasons, I didn't ask.
Answer -
Whats your oil pressure? On my 2g 4g64 no balance shafts its 90 psi cold start up 50-60 psi at cruising speed at normal operating temp and 14-20 psi at idle.
