i saw that.. i haven't seen any turbo setups

all of the supercharged vehicles i have seen get crappy mpg.. not that that is the most important on a jeep, but i'd rather not lose it!

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the air—these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

The HO was just an indication of the new intake and fuel injection system when the redesigned the 4.0 liter motor do differentiate it from the previous "RENIX" fuel system. The new system did include a very significant boost in power, without changing any of the mechanical workings of the motor, hence, high output.

True.

Based on my experience with the Wranglers, the 2.5 wasn't all that much better than the 4.0 when it came to mileage. I think I eked out 21 on the highway once or twice with the 2.5, where the 4.0 got high teens.

I can't see them calling an FI motor high output unless its supercharged or turboed but then again, that's marketing.

If you get a chance to drive a 4.2 carb VS a 4.0 FI, you will see the justification of calling it a "High Output" laughingdp

I'd drive the carbed I-6 about as far as I could kick that make the beast with two backsing carburetor

you cannot and will not tow shit with the 2.5

you want the 4 litre HO

it is the only way to go and you can get about 23mpg in the cherokee with it

plus you said you aren't interested in modding it so none of the axle preferences matter

the dana 30/35 will do you just fine

forced induction on a jeep motor is....make the beast with two backsing stupid comes to mind

it would cost less, make more power, get better fuel mileage, and last longer to drop a small block in one vs forced induction
