diesel turbos whats the difference!?

The Borg Warner S400 turbo is a very popular for v8 applications (single turbo). The reasons are that they are cheap (~$600), reliable(used in countless commercial diesel trucks), and can make some serious power (well over 500whp, 98lb/min rated for the 75mm wheel). The only real drawback is its size (40lbs, midsize turbo).

Here's a link to someone who sells ALOT of them.
