Renix Block in late model XJ

I have checked around and I think this will work but wanted to know if anyone has done it.

Has anyone taken a Renix block and put in into a late model XJ (2000-2001)

Everything else comes over from the late model XJ, only the block is being changed.
Anyone know of head mounting issues, power stearing pump or anything else?

I can't find exact information on this specific swap, only the HO head/intake to Renix.

Edit: Put this to modified as I wasn't completely sure if this would be considered OEM (despite using all OEM parts)

renix doesn't have the bosses to mount the coil. Not sure about other differences.

Yup. And on this one I would be doing a coil conversion as the 0331 head is junk anyway and install a 0630 head on with an adapter for the dual cat exhaust.

Sounds like you have the answer to your project. Any 4.0 xj,yj,zj,mj, and early tj block will work.

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)

5-90 stated in one thread that the Renix blocks were a higher nickle content iron in the casting. I have used two Renix blocks for strokers. One is in a 00 xj, the other is currently in a Renix Jeep, but it was in a '98 tj for a few years.
