Ramcharger Cummins Swap
« on: March 29, 2010, 01:11:30 AM »
ok so i have a 1986 Ramcharger, auto, 4wd, with a 318... i wanna put a 12 valve cummins into her and was wanting some insight from y'all bout how to do it.... ive been told that wiring should be easy... and i know that the front suspension will need beefed up and that i need to put a lift on it so the oil pan will clear the axle... i plan on runnin bigger tires and mainly use it as a daily drive, but will take it off roading (mudding, trail riding, etc) and maybe race it.... is there anything else i need to know before i embark on this adventure... any help u guys can provide would be greatly appreciated... thanks

There are a lot of reader's rides you need to read about first. Then gain some "experience" through their documentaries.

Check out the poll a few posts down, it has a lot of links.
Avoid replacing any part that you have not proven to be faulty through extensive testing.

IMO a 5bt is too heavy for a short wheelbase RC/TD..  A 4bt would be a better choice.
Your truck info goes here...

Will a 6BT work better?

I've been lookin for one of those 5bt's forever. Joe do ya gots a hookup on one maybe think ya could help a brother out? I'd probably trade three or four 4bt's and a couple 6bt's for just one 5bt... It would be the perfect size for a project I have in mind. The 4bt wouldn't be enough power and the 6bt is too large and heavy.. Help please sir!!!!

not only would it 'do it' but if you're looking for power and you're planning to 'wheel it I'd say (from a strength standpoint) the 60/70 gig is 'necessary'.

You won't need '1-ton' springs tho.  Regular off-the-shelf 1/2-ton units will work just fine.  Get the "4-inch-lift" units and you'll be nearly there.  LOTS of other options on leaf springs.  Surf around a bunch in the RC threads and you'll strike gold, specifically the rear 56" Chevy conversion with the shackle flip.  There's a lot of us running Chevy springs on our trucks because they're (1) longer, (2) less expensive and (3) available over the counter at most off-road shops.

Buy a rusty 89-93 4WD Dodge Cummins diesel truck and swap over all the required parts.  These can be sometimes found for $1500 to $2500 depending on condition (Watch Craigslist & the Ad Weekly).  Buying all the parts piece by piece is the most expensive way to go.  Also check with your local inspection station before you turn any bolts because in some parts of the country it may not pass any forms of an emissions inspection.

this is what I did and am in the process of doing.  I found a good donor truck, 200K 6BT, D60/D70 3.55s, G360 ... hoping to sell the drivetrain out of the 93 RC to recoup some/most of the funds I paid for the donor rig.
