Hi i was wondering if anybody new what size an fittings the coolant and oil inout are. I was guessing the oil was 4an and the coolant was 6an but i want to comfirm before i order them. Im using a jerry rigged banjo fittings right now and want to clean the engine up a bit. Also do you think 10an for the oil return is large enough?

On the turbo? They're metric fittings if you're wanting to directly adapt something to cool the turbo.

-4 for oil feed (since it's a journal bearing turbo) and -10 is perfect for the drain.

Use -6 for both sides of the coolant lines.

That's pretty standard for any aftermarket or retro-fit turbo install. The fitting sizes on the turbo are (I believe) 12 mm x 1.25 for the oil feed, 14 mm x 1.5 for the 2 coolant holes, and a flange for the return. You can source any possible adapter you'd need to go from metric to AN from Summit, Jegs, ATP Turbo, etc.

 

Thank you very much for the help!!!!!
