I now have a gt28 at 8psi, and was wondering if anyone has water-cooled their fit? I mean i've looked at it and i think the best way would be to run the coolant line that goes to the throttle body to the turbo n back, but i was wondering if anyone has done it a different way or how (if anyone) has done it at all.
Also does anyone know the pressure and temp max/rating of the coolant tb line

 

The HKS kit does it this way...no issues so far

 

I have run the coolant line from the throttle body to the lil t-bo i'm running. No problems whatsoever. =)

I also went to a larger radiator, but ran the coolant lines before (and now after) with no issues either way.
