Question about 1991 Jeep Wrangler
I have an engine out of a 95\96 cherokee, and want to put into my 91 wrangler. I have been told that because of the difference in the sensors and computers that it will be a waste of time and alot of money. Has anyone done this, how can I tell the compatability before taking out my motor and rebuilding what I got? The "new" motor came with the fuel injection system still attached to it. I was told that since the engine does indeed use a distributor that the swap should go ok, then others tell me that the difference in the computers (if there is in fact) will be more costly than just getting a remanufactured engine. Any help or web sites to visit will be great.
It's usually easier to downgrade than "upgrade"...As long as you can use all the sensors from the old engine, anything from the new one can be left in place and unplugged (such as if the new one has a knock sensor and yours did not, leave it in there and don't attach it to anything) By doing this you won't need to change harness or computer, and the computer will be getting what it needs to operate properly.Just don't use any new sensor unless it has the identical part number (it may look the same but values internally may differ!
