Default Turning up a 8.3 cummins

My dad owns a 98 Sterling L7501 dumptruck. It has a 250hp 8.3L Cummins. The truck is bone stock with only 27,000 miles. We were wondering if there is any way to get more out of this truck without costing to much money.

Thanks
Mike

we have a 93 f800 with a 8.3
it has the same p7100 pump my 5.9 has.

you can put a torque palt in it. gutt the afc turn the star wheel.

you can also buy marine injectors and such for it also. http://www.cmdmarine.com/commercialinboards.html

Depends on what pump it's got on it I guess, a P pump is fairly simple a cheap but if it's got a VP style pump then your looking at a programmer to get the gains.

It would be dependant on the age of the motor and what Tier it belongs to I think.

being a 98 its probably an inline pump, i think they stayed inline longer then the 5.9's did, two of our firetrucks have VP 8.3's

of course marine and on the road is different in some aspects

i know that even the new 8.3 now are still using an inline pump.
i'm not sure if it's still the p7100 or maybe somthing bigger now?
