We are, amongst other things, a Cummins engine dealer where I work. We end up with blown/damaged turbos somewhat frequently. The HX40 is typically not found on the B-Series (5.9 liter) engines that come in Dodge pickups. It is more likely to be found on the 8.3 or 8.8 liter engines found in larger trucks and machinery.
Also, gotpsi?, I had an even more difficult time finding HY35 turbos. Let me start looking again. I am on the prowl for a 600hp capable turbo.

EFR7064 T3 0.83 A/R DO IT.
The internal wastegate setup is on ******* point + the bigger the turbine wheel the more you'll notice the spool advantages of the lightweight Gamma TiAL wheel. It's obviously more expensive, but it isn't some piece of **** diesel nonsense.

click on "refresh maps". Most of the data put in is educated guessing. I picked out some mentioned, but they don't have any of the new EFR maps from BW.
For what it's worth, the Holset HE351CW has just about the same compressor as the HX40, but with a wastegated T3ish flange.

pretty sure my exhaust is what is holding my set up back (fm 2.5 down pipe - test pipe - racing beats power pulse muffler.)
boost pressure falls off after 5800rpms, 20psi @ 3800rpms to 15psi @ 7000rpms.
if i can keep boost pressure from falling off and a/f good, I'll be happy with keeping my holset hx30w.

Installed the reman'd hx30 crha, ran it about 15miles. Parked it at the store, started it back up after 30 mins. Damn turbo sounded like a vacuum and would not build any boost. Checked over everything for loose connections or oil supply problems. Found nothing wrong.
I went ahead and put my old turbo back on and it ran fine (besides the side to side play)
Reman unit is getting sent back now for inspection. Oh I love waiting on parts...

2.5" exhaust isn't gonna drop boost in the upper rpm. usually when that happens it's because the turbo can't flow enough air to fill the cylinders AND keep boost at that pressure. the small exhaust will slow your spool (slightly) and restrict your whp, but not cause boost to fall off. 2.5" is fine at the turbine, go to 3" as early as possible, as straight as possible, i don't run a cat only a 3" dynomax race muffler (straight thru design) that looks like a resonater and it's not too loud. the bigger the turbine, the more noise, but even on my galant vr4 with a ported t3/t4 and the same exhaust setup, but all 4" and it was fairly quiet cruising. wot sounded awesome @ 28psi

braineack the turbo sounded exactly like that, wierd thing is that I found no sign of compressor to housing contact. I personally thought the compressor wheel came loose and was freewheeling, or some how was not balanced correctly.
As for my exhaust situation, I plan to just run a downpipe and see if my boost doesnt fall off that way so I know its the exhaust holding me back and not the actaual turbo.
if boost stays where it needs to be then some 3 inch will be welded up.
I also picked up a 18psi wastegate actuator to make sure my door isnt blowing open.
