Im doing a full TII swap in my GXL but ive got no oil lines at all so im going to have to make them all myself. Its all going to be made with AN fittings and braided SS lines. Ive got the oil cooler lines down but I dont know exactly what kind of threads are on the front iron and turbo? I need to know the thread sizes for the turbo feed and return lines on both the turbo and the block.

Ive got a S4 TII block and an S5 turbo (bonus points for those who can tell me how long the lines need to be).


Edit: I searched and picked up 12mmx1.5 on the block, is this correct for the turbo size too?

 

that is the size for the block. For your turbo you will need a 1/4->4 AN for oil feed.

 

The turbo oil feed is not tapped from the factory.

We've covered this may times though. See these threads:
