im not sure that was my main concern but i talked to my buddy thats doin it and my cuzin thats helpin him and he said it would work...so they must not be variable vain.....other wise he'd have to come up with some kind of controll....either that or i might put an Hx35 with a manual waste gate on....not sure if that would be a good idea on a manual or not....

This may help.
"2007 Dodge Ram Heavy Duty trucks is an electronically-controlled Variable Geometry Turbocharger (VGT) and the 6.7-liter engine’s VGT utilizes 16 fixed vanes and a sliding yoke, providing variable geometry, as well as an electric valve."
Here is the site from where I got my info.
Dodge 6.7-liter Cummins Turbo-Diesel Engine
Hope this helps.

Not sure what you mean by 'pushing the limits on mods done to these trucks', but. . .

Any factory available turbocharger off of a B series Cummins (5.9 Litres) is going to be waaayy to small for a 7.3L PowerStroke. Especially considering we can put a factory available turbo from L/M series engines(10 and 11 Litres) on a stock injectored truck and have it spool considerablely well. Then change injectors on the same truck and have 400-550 RWHP capabilites.

most hx35's which is what cummins come with....push any where from 30-40psi safly.....i was told power stroke turbos can do that but not safley...also i was thinkin with a wastegate i could controll the boost and have it when i need it....maybe i should look into one of these turbos off a 10/11liter engine.... i just want more boost....im gonna try to find some head studs pretty soon....then another clutch...the south bend is goin dead one me haha

hmm I always thought they were a larger turbo.

Then again my truck at 20psi keeps up to my buddys moddified 12v that pushes 35psi on a stock turbo.
