Sorry to butt into this thread, but you guys can actually spool a hx35 with these 3.0L engines? Reason I ask is because I am a diesel guy (cummins) and come on here when my daughters sc300 is having problems. I know when a cummins is running crappy (fuel issues) that x-35 makes it a very doggy motor. On the other hand, one that is running very well, will over power the 35, meaning if it had more turbo, it could easily push it.
I saw someone mention a x-40. On anything less than a mildly modified cummins, that turbo would cause it to smoke like crazy most of the time. It is amazing to me that these little 3.0l can support these large turbos. My buddies truck uses a x-40 on a compound twin set up to light the switzer s-450 (a modified s-400). He actually uses a waste gate located on the exhaust housing on the x-40, to equalize the drive pressure so not to damage the shaft when he gets off the throttle (diesel lingo is "Barking" the turbo). It also allows him to run his boost pressure up into the 84 to 88 psi range with only having fire ringed heads, not the block. Hasn't lost a head gasket in over 2.5 yrs. Looks like I will be following these single turbo threads a little closer.
P.S. Truck is stock suspension, 4x4, single cab, with home made ladder bars, weights 5300# with driver, all stock internals (cam, pistons, block, stnd. bore) with the head being fire ringed. Running a Suncoast RH-47 dodge transmission. Has run a best of 10.9x's at 125mph.

I see where you are coming from, being from the diesel world and all.
I actually had a 94 P7100 12V.
The thing is, even a stock 5.9 cummins, has a pretty small turbo to begin with.
Is a Compressor that will flow 550hp yes, but at the end of the day, it has a T3 hotside.
Honda's run T4 hotside's before even the largest T3, and they go pretty good don't they?
A cummins should have a T4 1.06 hotside stock because it can spool it and make crazy power, but not everyone should be ripping around in a 1500lb/ft diesel!
Diesels run on detonation, so you can have a t25, compounded in a GT35R, running a T88. As long as the head stays on the block and you have the fuel, boost in diesels is "The sky is the limit".
