I am ordering all of my fittings and hoses from Summit, and I need to know the thread pitch of the oil supply inlet on a Garrett CHRA. I'll need a -4an to XX adapter, and I need to know what size to order.
Lets just say this... I'm over 100whp and soon to cross 200whp. Thanx 2GNT! Now if I could only learn to prove it.
