FWIW,
Cummins has offered the reflash to up the hp and torque numbers. Not ready for it yet but for those following along, if memory serves the numbers are appx 210hp and 385ft lbs torque.

Thats a mere 15hp less hp but 100 ft lbs more torque (true power measure) more than a Rover GEMS 4.6 V8 engine.

Unless I'm wrong (and I get reminded about that daily) that makes the 6L80e and NV4500 about the only gearbox choices.

I have heard rumors of people considering the Jeep AX15 manual transmission too. Supposedly it is a little stronger than the R380 and widely available/affordable.

Early on when trying to decide which way to go we considered the Aisin. After playing with the gear ratio calculator on the Cummins repower site the decision was made to go with the 6l80e for the 6 gear options and 4.10 diffs with a 1.2 tcase. The industry seems to be moving to more gears so that you can always find the sweet spot as opposed to being caught in between two gears and needing a split. Chris and Kevin @ Axis are working on making an 8 spd work.

This weekend we talked a lot about having stronger mainshafts made for r380's. Going to see if its possible to make an r380 stumpy trans that will hold up.

That would enable defender owners to not need to change seatbox, tunnel, floors etc and placing the engine further back eliminates the need to change the factory chassis mounts. Ie make this a bolt in. We preceive the primary market/application for these engines to be trucks that were rover 4 cyls that need either complete rebuilds or repower.

Sign me up. Great idea. I still want an 300-400 crank HP LS with an R380 stumpy behind it. This Cummins would be sweet too.
