Cummins powered suburban
Hey guys , I just pucked up a rust free 1990 suburban 2500 4x4 from California , I would like to repower the truck but say on a budget , I was thing 12 valve with a allison , I have a line on bus with a 542 allison , I know there limited to about 225 hp , I would figure my turbo 400 would be a better a choice .
Any one do any gm cummins conversion .
Thanks
greg

There's a shop in Austin,TX putting as 12V in a Suburban. They started with a 1993 D250.

1stgen545 was running a 545 in his truck for a while, but has since gone back to a 5 speed manual (I think). He would be a good person to get ahold of if you are considering that route, I do know that it is a very large trans and will probably require a body lift to fit it in your suburban. Good luck and keep us updated.

Keeping it simple is the best I agree ... The truck is going to be a project , I have a 97 dodge 12 valve I may retire the truck and pick up a Tacoma and use the 97 as the doner .
Its a 2wd so that trans is not going to work . I would love to do a manual but I don't have the best knee's and pushing in a clutch gets to be a pain in the butt .
With out a over drive this suburban won't be that great on the highway , so I may have to go with a manual .

You could even swap out the output shaft and tail housing on your 97 auto.
Another option would be to find a rusted hulk doner 1st gen from 91.5-93 and swap the engine/trans/t-case as a unit. Nothing simpler than the old first gens.
