Engine/Transmission (1994 - 1998) OK, question for the gearheads.............

[Got HO?]

I need some help on this one please. A friend of mine has a Cummins powered bus in his shop that we think has been re-powered. It has a 12 valve (I think a B series), non intercooled mechanically injected engine that I believe is not the original size that was in this motorhome. (Champion Motorhome pusher)

The engine number is: 562 02 623,



2 questions:



What can be done to bomb this engine so that he can at least keep up with traffic on the interstate?

If we can get good power out of it, I assume that engine life would be greatly reduced, correct?



You have to excuse my ignorance on this one, I have an '03 Common Rail HO & have not dabbled with the 12 valvers at all.



Thanks.

what year is it?

are the inj. lines in a row pointing up on top of the inj pump?

or are they on the back, in a round pattern, pointing toward the rear of the engine?

you may need to be on the 1st gen pag if it is not intercooled and has the radial pump. hope this helps.

Turn it up. Get the power he wants/needs. He may need to intercool the engine to keep the EGT's in check. Just the normal stuff..... Guages so he can keep track of what's going on. If he's looking to keep it for 500,000 miles... he may "only" get 475,000 out of it... . My truck has been bombed for about 50,000 miles... . the block has no ring ridge or any other problems.
