That's because it's a better engine <G>.

I've really embarrassed a few Mustang drivers with my little Cherokee,
that sucker is pretty fast. I expect that above 50 or so a Mustang
would pull away but in one of those little stoplight contest I'm not
going any faster than that... I'm no idiot and don't want to lose my
license for something as stupid as racing.

The 4.0 in my opinion has quite a bit of power for a V6. But I would also
like to find out some little mods to get some edge



I have to disagree..
I find mine slow. It has pleanty of torque, but as far as gettin on the
freeway or passing a car I have to pray for a tailwind and half a mile of
clearance.
Not to mention a gas GUZZLING 14-16 mpg! HFS!
I would definitely like to find some power in this little rig.
Of course, I went from a Mustang Cobra Convertible to this - so my judgement
mignt be just a little clouded that got 18 mpg with my foot in it all of the
time.

When it gets old and the engine finally dies, I am planning to transplant a
Chevy 350 into it I think.

But, I love myJeep, and wouldn't trade it for anything.
I think it's the most fun you can have with your cothes on.

To the original poster, the 4.0L is a I6, not a V6.

Kate, the vehicle will rust/fall apart before the engine dies! I
can't speak for the '06, but my '92 &'97XJ have getup and go. No
problems getting up to cruising speed, or passing vehicles on the
road, even with 31"x9.5" Swampers on them!

You'd probably notice a significant power increase if you took those
three cylinders that have been twisted out of alignment and move them
back so your 4.0 is a straight six like it was intended.

The cat back does seem to help a bit with mileage. Crunched pipes are
never a good idea and should be replaced no matter how many myths there
are about "liking restrictions". If you go much beyond a simple cat
back conversion, say to headers, you might need to worry about improving
the fuel injectors to avoid running lean which can also cause nox
failures on smog tests. Not that headers are a bad idea, just that the
combo of header and cat back can improve air flow enough that now you
are looking at higher flow injectors and possibly a bored throttle body.
By that time, might as well consider stroking it.
