meh im about to order all my braided lines and fittings and figured now would be a good time to figure out a restrictor.



i will be doing a 13bt, streetported, RB 85-90psi regulator, e-shaft oil jet mod, with a t78. The oil return line is a -10 braided line, no kinks, smooth downhill flow.



The oil feed line will be a smooth -4AN line, can anyone point me to what to use as a restrictor and what size restrictor would work good?



any additional info needed on the setup can be provided, im not sure of what exactly is needed to determine restrictor sizing.



thanks,

kevin.

on the TO4R garrett non HKS phoenix turbo said .65 but others say -3 line with -10 to -12 drain line.Thats is non Ballbearing CHRA.

GT35BB has a .35...I got that by accident.I have -4 and will try just the big return line. You will get an answer staright from a 78 owner.

uh oh... im running -4 feed and -10 return with no restrictor... maybe that will explain my smoke at startup when the oil pressure is at 120psi.



where can i order this?

I'd say a .080" would be a good place to start.
