Haya,

Anyone know the thread size of the large garrett turbos water cooling inlet/outlet?

Im making up the cooling lines for my HKS T51R (uses a garrett core) and the water cooling points are 16mm ID with a thread that looks finer then most AN fitting adapters.

Anyone know the thread size? Im guessing it will be metric.

Ahh...not really. I have since found what i was after. They are M18x1.5 to -6 or -8 adapters.
