Cummins 6BT Conversion...

Marine spec b has a governed speed around 4K, but they also have balance shafts fitted, not possible with an automotive spec sump as the balance shaft housing sits below the crank. Not sure I'd turn a stock internal b to 4K. Would be nice to have the 6BTM but, 380hp, 800ftlb out of the box.

Yea there figures are crazy..
My brother use to work a damler Chrysler in Adelaide and the motor that he bought was rebuilt by his mechanics and then traded in after 1000 hours..
Think he said he got it for $3g.
They dyno tune em..
His went close to 1000ftlb.. crazy as..

yeah they are bit of a torque powerhouse ! (i definetly would not upgrade much as 800ft/lbs) from what i have read the nissan gearbox's wouldnt hold up to these things ?
