My '91 beater needs a new engine pretty soon. I'd really like to drop in a 4.0 from a '99 so that I get the better intake, and it looks like using my old computer, sensors and senders will be pretty straightforward (might have to drill and tap for a temperature sender but otherwise it's drop-in).
Looking through car-part.com I've found a bunch of '99 4.0 engines, but the ones with low mileage are all from Wranglers. I guess they got rolled a lot more than the grocery getters...
I'm sure these things had the same block and heads as the XJ setup, but what about other stuff like intake, exhaust, tranny hookup, etc. Are they 100% identical?
Thanks
