i am going to be putting on my T4 soon, but i need an oil restrictor from what i hear when i am making the lines. but do you buy them? or can i make one? i would rather make something, personally. any one have pictures of what it should look like? maybe some sizing ideas.

 

run -3 feed and at least -10 drain. I used hard brake line for my feed (saved a lot of cash).

New Turbonetics units comes with a restrictor/filter. You can buy restrictors at ww.atpturbo.com

Also you can drill and tap the banjo end from your stock oil feed. Tap it to 1/8NPT then run a hard brake line as your feed. The banjo also helps restrict flow.

 

banjo bolts dont restrict much what so ever. but using a brake line is interesting.

 

they sure do for fuel systems.

Regardless, using the brake line has worked out very well, they're even resistent to rust! Both 1/8npt ends are already included. So just drill and tap your stock banjo, then get a 90o "street elbow" to go into the turbo feed port. With small brake line (I forget the size) you won't need a restrictor.
