Cummins R2.8 repower?

[twert1975]

Has anyone attempted this conversion in a series truck yet? Seems like it would be a great option if you could afford it.

There is a person here that put a 12 valve in a 109. Quality of work was outstanding but i hear i hear it has vibration issues at speed.

I am interested.

I am interested.

Me too, for a D110 repower. The thing is the costs don't jive. I'd love to keep my 110 diesel since it already is, but here's the breakdown:

R2.8 - $9000
Adapter to go to R380/LT77 - $2200
That's $11g's before a wrench has even been turned... and you know you'll need more parts along the way, and fab work.

I can do an LS1 swap for probably less than half that.

But depending on how my Toyota straight 6 swap in the 109 turns out, I may go that route on the 110. Hell I have a 1JZ just laying around.

I agree, but I have also been quoted $10k - $15k for an upgraded 300tdi with upgraded intercooler and necessary accessories including install of everything.

I'd think the 4BT would be an easier and far less expensive option. A friend recently put one in an F150 and it netted 400/700 power numbers using a stock 6BT turbo and a large intercooler. That was about a $15k project. In stock form, the power numbers aren't worth the effort IMHO.

There's a few guys who have done the 4BT's in Rovers. They have mixed reviews. The 4BT is heavy and noisy. A Series Rover isn't known for its sound dampening, and the engine noise coupled with the road noise I hear is excessive. That and a few other driver annoyances. Most said they wouldn't do it again. The R2.8 I think has enough refinement to be a good fit. It's primarily a cost issue for me, but I'm a few years away from redoing my 110, so maybe I will revaluate it then.

I too looked at this swap... I have an Series IIa 109" military-issue diesel with a non-Rover replacement engine (replaced in 70's or 80's). Though costs would be high they would not be prohibitive - my concerns were that the drive line couldn't handle 200hp/400lbft - replacing everything under the truck then becomes too complicated AND cost prohibitive. Would love to be convinced otherwise...
