Looking at used turbos
 

Just wondering what everybody recommends as far as Turbos go. I can't afford any of these aftermarket kits, so I'm just planning on buying a used Turbocharger, rebuilding it if necessary, and having a shop do all the plumbing. Thing is, I know nothing about turbo sizing and I've been reading alot of tech articles saying that's really key to making the turbo mack with your engine and run smoothly.

I been looking at the stock Garrett 6.0 PSD units (which I CANNOT find a model/designator for), Holset HX35/HX40s, Holset WH1C, Garrett GT37VA, Garrett GT4294, Holset HT60, and Garrett GT35R on craigslist. My question is, what do you guys think would work best on a 6.9 IDI?

No on the 6.0 unit, no way to control the vanes for the VGT. HX35 should work well if you are going to do custom plumbing, that was my original intention when I put the HY35 on mine. Couldnt make the HX work with ATS though uppipe. Good thing about the Holsets is they are fairly common, cheap, and very tough turbos.

My friend has two 7.3 s with factory turbos for parts one is 96 and the other is 93

Where's he located and how much does he want for each of them?

I bought them both. I live in trinity tx

If ya need parts just let me know

I woulod buy a hx35w and put a blow off gate between the turbo and the intake so you dont go past about 12 psi ...

I get 40 psi on my cummins but ... cummins runs 17.5:1 not 21.5:1 compression ratio
