Thread: Help with this?

When you buy this...
Circuit Sports S13 SR20DET Turbo Lines (Bottom Mount)

It comes with an UNrestricted oil inlet. But i have to buy a restricted one. But the site does NOT say what AN size the oil line is. (-3 or -4)

So im at a loss which one i need to buy

Does anyone know?

-3 size Oil inlet fitting for GT28/30/35R with built-in restrictor: atpturbo.com
-4 size Oil inlet fitting for GT28/30/35R with built-in restrictor: atpturbo.com

I have the same lines, I just used the stock restrictor in the banjo bolt and didn't worry about it. There kinda tough to fit but they work.

Thanks!!!!
