LJ 73 LV engine swap (1 Viewer)

[anavant]

Hello 70 world. I am new to your world and reaching out for some some advice. I have a 1987 LJ 73LV ( 2.4 T) that I believe needs an engine swap. The truck is putting out copious amounts of smoke going down the highway and feels sluggish. Does anyone have a suggestion of what I can find here in the US as a candidate that would mate with the transmission?
I found some older posts mentioning the 22 RE if I wanted to go with a gasser.

Any input is much appreciated.

Before swapping it out you should at least do a compression test. If compression is good, I'd be looking at the fuel system or turbo seals - may just need some maintenance.

Or maybe you just want to get away from diesel completely.... Having driven 22RE and 2LT(E) vehicles, I personally much prefer the 2LT(E) - especially when tuned up a bit.

We're just finishing up swapping a Cummins R2.8 into an LJ70. It's not the cheapest solution, but bolts right up to an R151 trans and has plenty of room underhood. At 160hp and 300ft-lbs it's got a lot more pep than the 2LT which was in it. Build thread... Machito the LJ70

We buy direct from Cummins since we are part of their builder program. You can also buy direct from them as an individual, or from a number of other sources.

The R151 adapter comes from Quickdraw:
