hey guys.. been gone for a while (even though i'm still a n00b) been really busy lately.

so, i've been kicking myself in the booty and head lately for deciding i didn't 'need' or 'want' 4x4 when i bought the Jeep back in December.... so many trails and such out here in the desert that i'm pretty sure the 2WD could handle, but i just don't want to be stuck 4 miles from the nearest cell phone service area. haha.

I went driving out on some desert trails (Jeep is completely stock) and there were a few areas on the packed sand inclines where i almost had to back off that kind of amazed me.. bummer.

i'm really hoping some tires will make it a little more capable or at least some decent trail riding or i'm going to cry.

one thing that i have never seen on here is anyone boosting a KK? is there a reason that no one has at least thrown a few lbs of boost to the KK? I know some motors can't handle much because of high compression and what-not, but is it the fear of weak components or what?

I was really contemplating a simple, remote setup (4-5psi)

anyone else have issues with the windshield cracking without a rock chip? mine started cracking at the bottom (4" crack now) about 2 weeks ago.


the future for my pathetic 4x2 Jeep will mostly be asthetic, as i don't want to invest in a locker and then be denied for warranty work.

I am hoping to see the new KK renegade headlights pop up on ebay within the next few months so i don't have to worry about trying to crack mine open again to paint the housings.

my list of things i'd like to do:

tint all exterior lighting
tint front pass and drivers windows
black headlight housing headlights or tinted
goodyear wrangler authority tires (as big as possible without lift) as theres no point to lift the incapable 4x2. haha
cragar v-5 wheels (cheap as hell ans will match the black on black on black on black theme)
magnaflow muffler (so it doesn't sound so pathetic)
custom CAI

possible:
remote turbo setup (small-mid size turbo, 4-5lbs of boost) still need to find some things out about the motor.

i will also get some new pictures of the stock KK driving thru the wimpy trails. haha

I think the main reason for not adding boost is because we all know we drive bricks. Our KK are not really build for speed. I think we would rather spend the money in making it more off road capable, towing or roof baskets or racks would take priority. Boost does not equal better off road so we don't focus on it that much now torque we like. An option is to take a look at Dodge Nitro forums and see if someone has done something like that. I know they focus on that more than KK owners. At least in my opinion that was why I wanted the KK instead of the KA, Nitro lacked the 4lo. Sorry for generalizing, but I think we have all thought about the adding HP to our KK but have ended up doing something else w our Jeep, on the other hand I have seen on the road some Dodge Nitro that have been lowered and looked tricked out. Example http://www.babez.de/dodge/dodge-nitro-57l-hemi.php Yep, that is a sick Nitro.
Note: I guess that would be another reason Daimler-Chrysler decide to give Dodge 2 engine option and not the Jeep .

There was a guy that added NOS to a 3.7L Trō, Blew the engine all to he!!.
They are just not designed to handle it.
Until someone comes out with a programmer for it, there really isn't much that can be done.
You could add a small boost (turbo), but the system won't work right without the programming.

yeah, i deal in turbo systems all day long. with low boost levels, you can easily get by with a bit extra fuel and light tuning.

i just figured i might throw boost at it for 30-40lbs more torque for the fun of it, since its not 4x4 and i can't really do anything else. I can put together a decent system for under 800$ which is why i was kind of hoping the Jeep would be an OK candidate.

I can't find MUCH info on the engine, other than it has a cast iron block and 9.7:1 compression which both make it seem like it would be a decent option for low boost, but with the aluminum pistons and powder rods, makes me a little uneasy.

ill check out the nitro forums and see if theres anyone thats done anything like this, thanks for the suggestion!

Here is something interesting i came across..

Kenne Bell used to produce a supercharger kit for the 3.7L yielding very significant gains, but apparently stopped production due to the lack of demand. I am going to try and get in contact with someone over there and find out if there were weakness issues or just simply lack of interest. I know I can't really trust the answers to much, but it would be nice to know as much as possible before I attempt to blow up the 3.7L.

http://www.kennebell.net/superchargers/dodge/liberty37/libert37.htm

good gains also..

from 166 rwhp to 235
from 193 rwtq to 275

their kit would have been pushing quite a bit more boost than 4-5 lbs to reach those numbers, even with the twin screw.

IMHO

Put a LSD in the back, warranty work won't notice that.

Lift it, have you seen the 2WD class SCORE trucks? Also, you aren't limited by the CV angles

you shouldnt boost the 3.7 because of the position of the piston rings. they are to high and the motor is easily blown. the supercharger was taken off the market because everyone was blowing motors. buy a cheap locker and some tires and go to town.

...or trade it back in for something (anything) 4WD.
