Can a different year engine be used for a 99 limited?
 
I have a 99 limited I-6 and I'm being told that the engine is specific to that year and model. Can I use an engine from a different year and/or model? It seems to me that the I-6 should be the same for 99-04 but I want to make sure before I spend money on the wrong motor.

I'm not intimately familiar with WJs so take everything I have to say with a grain of salt but.........

From what I've seen of 99WJs, they have the same DIS and 0331 head as the 00+ XJs, have the AC compressor in the lower drivers side postition instead of the upper passenger side postion, have the alternator located up high, and have the belt auto tensioner.

So those things being said, I cannot see why any WJ or 2002+ TJ 4L wouldn't work. But like I said I'm not the most knowledgeable about such things.

I did run into a 4.7 year issue a while back. It had to do with the crankshaft sensor reluctor wheel on the crankshaft being different.

The salvage yard should be able to tell you what will fit, they have interchange manuals that have parts listed and what they fit.

Any year I-6 should work as long as it is using the J-Tech computer(separate engine and tranny computer)I think '99 to '03 should work. Double check '03 cause it could have been a mid year change to the other computer.
