It is the hottest mechanical pump available for these engines. I replaced the factory head bolts and main bolts with ARP studs and I'm using a DSG main girdle to help prevent main web cracking. I am thinking about intercooling it as well, but I'm not sure about that yet. I'm going to run a 4" Jardine exhaust with a K&N cone filter on the turbo. These engines have a wicked sound with the airbox/silencer removed with big exhaust. The exhaust note sounds like a big block with a rattle, and the turbo whines like a kid wanting candy!
Here is example. I really hope mine sounds as good!

That thing sounds pretty damn sweet. You know that 6.5 is a good option for your build because they are much less of a listed item than a Duramax.
