turbo oil feed thread
 

does anyone know the thread specs for the oil line to the turbo? where it threads into the oil filter housing?

i know its a oringed boss fitting

ive seen sizes from summit or lefthander chassis that include
3
4
6
8
10
12

i just need to know what size that boss fitting is!

The fitting that goes into the filter housing on the engine is 1/8th npt

no the accessory one is 1/8inch npt, the main one is a metric thread i think. but its an oringed boss fitting
