I dont know if you can get one _new_ rebuild might be your closest bet.

Jasper sells rebuilt motors and transmissions. Might want to look up their web site, i believe you can get prices there.

However, thats the motor, not all of the accessories. You'll usually need to buy fuel delivery, water pump, alternator, PS pump, starter, filters, and whatnot separate. The good news is, i belive the 89 is TBI, so there's no computer to worry about.

I have a 90 2.5L in my basement if you're interested in that. I'll sell it cheap, as ive never run it myself. It turns, and before i disconnected everything I had it cranking with the starter. It needs some clean-up, and a new throttle body. Otherwise, as far as I know, its in good shape, or so i was told by the guy that gave me the jeep it came out of. Not sure where you are, but pm me if you want to entertain the idea.

I just ordered a 2.5L AMC150 TB from S and J engines. With engine/core/freight it was $1825. Adding in other parts, water pump, hoses, etc looking at another $300-$400. Mechanic said books around 11.1 hours for remove/replace. Mechanic cost is around $75-$95/hour.

Anything fuel injected has to have a computer for the fuel injection system to function properly. All YJ 4 cylinder models are fuel injected from the factory, the 1987-1990 models are the only models that are TBI. Everything 1991 and newer is the more traditional MPFI system.

To the OP:

A total overhaul with new parts would run you in the ballpark of $2500 or so. You are the one who has to do the shopping and research, we can only help you so much. Just FYI, stay far far FAR away from AutoZone master/slave clutch cylinders. They are garbage, my last one blew after about 6 months. It is an internal setup, you have to drop the transmission to replace the slave cylinder.
