Perhaps a bit different turbo question?

Okay, here's the deal. I have a turbocharger from an early '90s 5.9 L. Cummins diesel engine that was in a medium-duty truck. My car is a '95 Corvette with a 388 stroker small block LT1, all forged but a street build and daily driver. Current naturally aspirated numbers are about 400 HP and 445 lb-ft of torque at the rear wheels. My questions about adding this turbo are this. Since the Cummins' maximum RPM is roughly 3000~ and my car makes maximum HP at roughly double that, would my engine spin this turbo too fast? Due to limited underhood space, I'd be mounting it in the rear of the car, behind the differential where the spare tire used to reside. I'm totally capable of fabricating the piping, oil lines and such so that's not a problem. And while I'm not overly concerned with a slight amount of lag, would an air cooler of some type be advisable?
Just as a bit of background, I've worked on turbo engines for years, but only in stock applications and mostly on diesel engines. I'm also a life-long hotrodder, build my own engines, etc. Thanks for any insight that may be forthcoming.
