Been trying to sort out rebuilding the existing motor or finding a donor. I finally found a 4.0 with 40k miles and a mild build. Since it is out of a 02 TJ I'm still researching pros and cons but I hope to have this thing installed by the first week of December.

 

Hey bud,
Im in the same boat. I lookig for a solid block.Think its time for the stroker build! Thikig a 4.7, but smog is always a bummer.

 

Yeah I'm back to the drawing board. TJ motor won't work. I'm hesitant to go stroke cause of the mpg I currently get. I'll probably end up matching a 7120 head to a newer block and do a mild build. Reliability is the main goal.

 

Mild stroker would be cool.

Stole this from cruiser


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)

 

After bouncing back and forth on the idea of building a stroker I ran across a good deal completely rebuilt 4.0L with 0 miles and a 30 day warranty. Engine will be delivered Saturday with the swap scheduled for the beginning of January.

Thanks for the CL find littlebuddy.

 

Snazzy!

 

About time

 

Thx whres for working out all the details and taking delivery.

 

Mounted up. Ready for a cleaning and some paint. Nice to be getting closer to the swap.

 

Snow Day!! Well at least in VA they call this a snow day.

 

DUDE. Good to see that thing in motion lol

 

Very nice.

 

Oh its angry and doesn't hide it. I have to drive around with the radio off so I can monitor what the engine is doing.

 

Parts are starting to come in. Welcome to the world of a 01. Are 4 O2 sensors really better than two CA? Thanks for that...

Looking forward to the electrical system upgrade and a 160amp alt.

 

Is that a rewound alternator or the bigger one like i have? I have an alternator bracket that's already clearanced if you want it
