Good luck. I steered away from therm back in 2009-2010 when I was looking for a forced induction solution. I talked to Sam quite a few times and never felt like I was getting good information/answers, but that is only my opinion. I made a statement about not giving GTM any of my money ever and got ridiculed for days on end.
My Greddy manifolds have not cracked and my journal bearing turbos w/o water cooled cartridges (20G-10CM2) are still running strong. The only issue I have had with my build is that I am on my 3rd CSF radiator. And they just released a revised one (FML).........
