yesterday i bought a 86 ranger that needs a new motor(2.9).... my question is, is there a better engine, that is more powerful.... but at the same time still fuel efficient? also is the 2.9 a good towing engine? what is the grand toltal of a engine/tranny swap?

engine) 4.0L would be the most strait forward

fuel economy) No free lunch

towing) depends on what you're towing and what gears, I wouldn't want to tow much with an A4LD automatic, as least not with out an upgraded cooler.

cost) a vehicle is as only as cheap as the person doing the work. Hard to estimate that since there's no definite costs involved. It's as cheap as you can do it for. I guess it can vary from $10 (yes, there are people that claim this sort of total price on swaps) to a few thousand. Just depends on circumstances. I would expect a few thousand just in labor to have a shop do it, so either way....

thank you for the reply..... what do you mean "no free lunch"?
according to the tech section the PO. replaced the tranny with a 4R44E or 4R55E id'd by the pit in the pan......

What I meant by no free lunch is that more power is always going to come at a price of more fuel consumption. But on the other hand, a 5.0L in a Ranger gets fairly similar fuel mileage as a 4.0L would; just because the engine doesn't have to work as hard to obtain the same result. Anything beyond that and economy will suffer. Just a lot of factors, 4.0L mileage won't be terrible, but really not that great either.

The trans you listed is a computer controlled trans, are you sure that is the trans in your vehicle? It would need something to control it for it to work correctly. '95, they went full electronic and it wouldn't work with your current engine management system.

The rangers and bronco IIs come with various gear sizing ranging from 3.45 to 4.11. If your ranger has 4.11s and smallish tires, a 2.9 in decent shape will probably do alright for towing (of course a lot depends on what you're towing and what kind of terrain it will be over). With almost anything that tows, an automatic transmission's life will be shortened quite a bit.

4.0 or V8. 4.0 is about as easy as it gets though. And well worth it

the reason im trying to avoid the 4.0l is because, me being a worry wort, am worried that when i do the swap and drive it around i will shred the rear diff(or for that matter the front diff) or transfer case. eventually i will go to the 8.8 and d35 but im not made of money.....
what would be a good price on a 4.0 donor vehicle?

Good luck. They didn't start putting 4.10s in them until the IFS front end, which is not compatible with the TTB.
