On the 6.7 Cummins, I've seen the HE351 put out 30 psi boost, so it might be a little oversized. It will probably get the job done, however. You might want to look at one of the wastegate turbos off the pre-2007 5.9 Cummins. With a compression ratio of 24, I would be careful with adding too much boost because of high cylinder pressures. If you really want to do it, you may have the beef up the head bolts, etc.

As a fellow diesel guy, I'd love to live next door to you! I'd love to have the shop/tools/money/time to do some of these types of engine mods.

My version of energy storage is called "momentum".
My version of regenerative braking is called "bump starting".
