cummins engine swap

what does it take to swap a 5.9 cummins it the place of a 8.2 detriot in a 90 foretravel rear engine motorhome

Your question is not a simple one to answer. Not sure anyone has ever done that mod. You would need a new mounting system that made sure the engine sits at the same angle as the Detroit. Among many other things plus a different control system. Your better off rebuilding the detroit than trying something like that.

I am sure that it can be done and probably has been, but my experience tells me that you would be better off and money a head to sell it and get another motor home with the engine you want already in it. I am not sure on the smaller diesel engines but is the Detroit a straight six or is it a V8. I think that the Cummins is by far the better motor of the two, but I have also heard that some of the small Detroit's get pretty good fuel economy.

i have a chance to buy a 90 grand villa cheep that has a bolwn up 8.2 and alison trans in the rear. i have found a 5.9 cummins and a allison trans out of a 96 front engine motor home for $2000 think i could put it togather all for under $5000 would it be worth trying

put a 3208 in it, it will fit better

Yes

Good motor albeit old tech.

Also was an option , I believe in that Motor home so should fit without too many headaches IMHO

A good used one should be reasonable

In a prior life I was a truck driver so I am familiar with the larger diesel engines mostly the Cummins n14, m11 and L10s. I guess the only concern about the Cat is parts availability and price, now that Cat has decided to get out of the truck motors.
