you only need restrictors on BB turbos. -4 is fine. if you can go -12 on the drain but -10 will work.

i'm stuck with a -10 that was already on the oil pan my kit cam with or i would. sounds good, i'll have to pick up a -4. i had a feeling this -3 was gonna be too small.

thanks for the input guys!
