What turbo comes on a commuter bus?

Might seem like a broad question. What turbo comes on a common rail commuter bus (with a Cummins motor of course)? Got a friend that works for the transit authority that said he could prob get me a turbo if I needed one. Just was curious if they were any good for performance?

On our buses it is the same turbo that comes on the pickup version.

same here the 12v bus engine i got had the same as a truck and even the 8.3 in our equipment has the same turbo as a truck engine.

nope not the same, he asked about a commonrail guys not mechanical, they have a he351ve, this is not like the ones found on the newer trucks, they are pretty hard to adapt, these units are water cooled and from what i can tell, they dont flow that much air, they have a pretty small downpipe, like a 3-3.5", and if you were to look inside the exit of the turbine housing, you would find this very restrictive ledge. i believe they use this for backpressure, and the egr flow. ask you buddy to take a pic, and see if they look like a hx35, or what i just described.
