What other block can I use for my 03 l6 Cherokee? I doubt I could use the earlier l6 blocks as they have distributors right?

 

98 & earlier have different motor mount locations.

 

so 99-03 are compatible?

 

99 and up WJ and TJ engines will work. You can not use an XJ engine.

 

ok, thanks. good to know. I guess my options are limited.

 

Anyone in the mid cali area have a good short block for sale?

 

So if I get a 99 l6 I can bolt up everything from my 03. intake/exhaust mani's, head?

 

As long as it's from a 99 WJ or TJ.

 

sweet! Thanks a lot! This is the donor jeep. Guy wants $300 for complete motor.

I learned this the hard way. My xj started as a donor to my WJ. 99 X to a 00 W. Wondered why the oil filter way in a different position. Learned a lesson.
I know that the 99 originally ran a coil pack for ignition but my motor has a dis. I did know it was not the original so someone put a different motor in. My guess is it's just the mounts that changed. Everything else either fits just right or can be converted (position of A/C and alternator etc) if I understand correctly.

 

Wait! Didn't Busted just tell you an XJ motor wouldn't work?

 

Your WJ brackets won't bolt to the XJ block. Again, you need an engine from either a WJ or TJ, NOT an XJ.

 

Sorry guys. I didn't realize that xj's existed in 99. I thought all cherokees in 99 where wj. That's why I'm confused. So I'm back to square one.

 

This may help:

XJ Cherokee and ZJ Grand Cherokee 4.0L engine blocks interchange.

2000+ TJ Wrangler and WJ Grand Cherokee 4.0L engine blocks interchange.

XJ/ZJ blocks and 2000+ TJ/WJ blocks do not interchange without significant modifications. (1991 to 1995 YJ and 1997-1999 4.0L TJ Wrangler blocks will interchange in XJ/ZJ and visa-versa).

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.


XJ: "Regular" (not Grand) Cherokees 84-01
ZJ: Grand Cherokee 93-98 (Gen1)
WJ: Grand Cherokee 99-04 (Gen2)
YJ: Wrangler 87-95 (Gen1)
TJ: Wrangler 97-06 (Gen2)

 

Thank you! That's answers my question!
