XJ Parts That Fit TJs

[piratelife]

So I have a 2001 XJ classic I'm about to part out with a newly reconditioned 4.0 and upgraded suspension. What model TJ am I best looking out for to swap as many parts over as possible. Oh, I'm lazy so I'm looking for an auto TJ too... I'm looking at taking a TJ back to bare bones and fixing it up from scratch. Cheers in advance for any info.

There are several variations of the engine that make some models easier swaps than others. I've found a writeup before, but it may have been on naxja.

A quick search turned up this, but I have no idea if it is complete or even correct.

• XJ Cherokee and ZJ Grand Cherokee 4.0L engine blocks interchange.
• 2000+ TJ Wrangler and WJ Grand Cherokee 4.0L engine blocks interchange.
• YJ and 1997-1999 4.0L TJ blocks will interchange in XJ/ZJ
• XJ/ZJ blocks, and the 2000+ TJ/WJ blocks do not interchange without significant modifications.

TJ/WJ 4.0L Engine blocks underwent clean sheet design changes effective in the 1999 WJ Grand and 2000 TJ Wrangler. These blocks are not interchangeable with XJ/ZJ engine blocks. The reason is motor mount bolt holes and belt driven accessory mounting bolt holes are in different locations, or not present at all, TJ/WJ vs. XJ/ZJ.

I used a 96 zj block for the stroker build in my 97 tj.

The front dress and motor mount bolt bosses Are different on early and late 4.0l's. It's just a matter of when the various platforms were transitioned or in the case of the xj and zj,eliminated before being transitioned to the new front dress style
