335D twin turbo specifications

Hey everybody. After getting a dyno (mustang) today I got to thinking about turbo specs on the D. While waiting for my car to be mounted on the dyno I eyed a large brand new Garrett turbo sitting on the counter. The service guy goes on to tell me that "yeah this thing is good for 750 HP.". Holy $&@!! "yeah it's going on a 300zx to replace the twin turbo set up". So I ask you my fellow Diesel heads.....

1. Anyone know what both stock (small & large) turbos are rated to?
2. Is it the same as what the transmission is rated for?
3. If so, then how does the JBD Play into all of this? (100%, 80%, 65% )

Also, in case you were wondering, my numbers were OK I guess. 272HP & 431 TQ (both at the wheels) service guy said usually they estimate a 15-20% loss for those numbers on the dyno. Inquiring minds want to know.
