3.4 is an ideal swap for upgrading from a 2.8, since it's the same block and already set up for a V6.

 

If you're looking for ease, simply replacing the 2.5 would be your best bet. If you don't mind doing a little bit of fab work and wiring, a 3.4 would be good though. The 2.5 uses the same bellhousing bolt pattern as the 2.8 and 3.4, so you should be able to retain your transmission and driveshafts.

Once upon a time I tabulated a lot of random data I've gathered on swapping a 3.4 for a 2.5. It's in a word document located here:

If you aren't a member at our old yahoo site, you may have to wait a day since I'll be on the road all of today and can't approve you until I get back home. but I'll get on it asap. :thumbsup:

Here is what you do.

 

1. Buy a stock 4.0 MJ

2. Swap your steering, suspension and any other desireable parts onto MJ #2

3. Sell the old one complete with a cracked block.

4. Enjoy your new found power and fuel injection.

 

That is a hell of a lot easier and cheaper than a 4.0 swap, or most others for that matter. If your smart you'll actually come out ahead :thumbsup:

:agree: but if you are set on a v6 i like the 3800 motor, or 4.3

3.4 liter is the only one that actually bolts in directly.

 

3800 and 4.3 take ALOT of mods to put in.

Unless your planning on doing a v-8 swap later... Just plain ol' buying a 4.0L MJ is cheaper, and easier by far.
