4.0

Couple reasons for the 4.0. It is bulletproof, easy to work on and if it's under powered with stock 3.73 gears and over sized tires, re gear, problem solved. I'm running 31s on mine with 3" lift and lock right in the front, I might re gear but it's my daily driver so I'm undecided. If I do I'll only go to 4.10s. Off road the thing is unstoppable on the Yokohama geolander ,at/s. Love my zj.

Try driving a 2.5L for YEARS then come back and tell me the 4.0 is weak It is not, the automagic transmissions really ruin it though, not enough gear refinement to get all the power out of that engine. The V8's do a little better with the auto behind them due to the extra torque and HP, but I still hate automatics with a fiery passion.

As for highway MPG, the MPG meter thingy on my 96 5.2 said I was getting around ~19mpg average just cruising on the straight and level.

V8 if towing a lot over 2,000 lbs or doing a lot of highway driving. If mostly around town driving 4.0 is fine. I have one of each and use the 4.0 ZJ for most of my local driving. Towing the boat or highway road trip out comes the Hemi.
Keep in mine the 96-98 V8s have the aluminum Dana 44 and they are known for noise problems. On the ZJ with the iron D35 I never had a problem in 15 years and 146,000 miles.

V8. Thats the point of having a Grand. For the big motor. If youre getting a 4.0, get a cherokee

X3 I am an XJ owner but it wouldn't be worth it to have to live with all the quirks of a ZJ without the power of a V8.

My first ZJ was a 4.0 but the last 2 have been 5.2's if that tells you anything. Power on demand.

5.2. He'd be wishing he got one of he didn't. Gas mileage isn't that much worse in the 5.2. It's quicker on the acceleration. The 4.0's are known to get cracked manifolds I believe it was. The 5.2's will only give you a leaky plenum. I'm on my second 5.2 and love it.

Four things:

Our 4.0 ZJ gets 21-22 on the interstate, 22-23 if you keep it at 60mph and just a touch under 20 overall.

If I can't get 'er done with a 4.0 and the right gears I don't need to be doing it. (Old man syndrome)

Grands have more room, the ONLY reason to go with one over a base Cherokee. If you don't need the room get a Cherokee for the better/cheaper aftermarket support.

I have absolutely no time for FT 4WD. Only reason for it is so city husbands don't have to have their city wives figure out how to throw a lever when the pavement gets a little slick.

Any guess' to how I voted?

Hmmm you don't have time for full time 4wd? Wouldn't that mean you have lots of time? I wish every 4x4 came with the option of full time 4WD! After having my Audi and my 4Runner both with Torsen AWD I don't see why anyone would want part time 4x4. When my XJ was "broke down" due to DW I took my 4Runner out on the trails with my Jeep club and ran everything they did and never had to touch a button or lever once!

I wouldn't touch a jeep without FT 4WD, even on dry pavement they handle better. Rain? Bad road? No contest.
