im trying to make an oil and water line kit for a gt3076r that hasnt come yet and i dont know what kind of threads they use. i was looking on the atp website and it looks as if its 14mmx 1.5 pitch, but i just wanted to make sure. all the turbo diagrams i look at dont show the thread specs.

thanks

 

someones gotta know!.....?

 

You're correct. That is standard on all the coolant passages on the Ball-bearing cartridges.

 

you can also use a 1/4" npt for the coolant.

 

ATP sells an overpriced kit with all the fittings for oil and coolant on the GT turbos.
