cummins qsm11

Hi everyone, I have a cummins qsm 11 670 HO and was wondering if this can be converted to a commercial and anybody any idea what would be involved.

cheers

I have two HO in mine.

It's the same internals,just with higher boost and more fuel and reprogrammed ecu.
They use unit injectors and not the common rail/piezos so they are cheap.
Best bet is talk to a Cummins tech and/or boatdiesel.com.

Either way,they'll last a very very long time-25k-30k hours- in lower hp form.

Only issues with them are:

-exhausts can leak a bit after 5-10k hours. Just tiny black soot marks on the engine. Ignore.
-coolant resevoir bracket can crack. Replace.
-oil seepage on the gear case. Replace or ignore.
-use Cummins air filters only.Others may fall apart and wreck the engine.

Baffling to me why other guys with other engines- with known major issues-insist their engines are better.
