Turbo recommedations for 475+ HP

[WadePatton]

Bear with me, I've read all the turbo threads.

I'm going to add DD3's and a larger turbo. I've ruled out the tuned HX-40 because everyone agrees that 450 is really the upper end of it's optimum performance. I'd rather be overcharged than under, and I don't want to go through two turbos to get the one I should have bought first.

My truck is an ETC, with DDUFM drag, Six speed. I don't tow heavy and operate at 600-1800 elevation in the South. Truck now makes 343hp and should be close to 475 with 3's UFM and 40-class turbo.

I also plan to add an ATS manifold, fix the supply fuel and work on my cold air. And I don't want to run pressures that threaten my head gasket. Plenty of time for that later.

I'm looking at the Piers 50, KSB1, or something from Pius. There is a lot of info out on the 50 and KSB1, but it is very difficult to get any info on Pius turbos. Joe says there's a Pius "Schwitzer" that is similar to the H2E.

Thanks to the vendors that have been fielding my questions so far. Now to hear something from the street. TIA
