Wrangler modifications

Hey y'all,

I've got an 02 Wrangler. Had it for years, but haven't done much to it because of finances (college), but I'm just about done and consequently will be getting a job. (In theory that means more money, but in reality...let's just stick with theory.) I haven't done much with her, besides Banks cold air intake, exhaust, and headers. Right now I'm running on 235 75R15's. They're a bit kinder on my milage than the 31" or 33" tires that I will be moving up to, but if I want fuel ecomony I'll ride my motorcycle. I'm fixing to get her ready for some trail riding and such, but I'm not sure where to start. I have to do it all in stages because I can't afford the price tag of it all at once. I think I want to finish with any power mods first. I was thinking about a performance chip, but I hear horrible things about them (I might pick up a cheap on and see what it does). Beyond that I think the next step is gears. Any suggestions on what I should do and in what order? Also, what do you think about the computer chip idea, and what's a good gear ratio to shoot for if I'm using 31" or 33" tires? Thanks.

Jack

what kind of tires are you planning on running after all? 31s or 33s or bigger?

If you are planning to hit the trails, better think about some lift and armor. You really don't need a lot of power for offroading unless you are really planning to go hardcore. Torque is the magic word.

I'm going to go with either 31 or 33, I don't think I'll need anything bigger than that.

Depending on what gearing you have is what i would choose my tire size for now. With my jeep i have 307 gears and i have run 31's with no problems. i would not go bigger than that though. I just kind of depends how you want to spend your money. I would say do 31's first, get a small lift like a rustys 2 inch (i just put one on 2 nights ago and it rides like butter). Then do gears a locker up front and then eventually 33's with 1 more inch of lift. And in between all of the saving for big parts you can buy little bullshit to keep you interested. IE ( hi-lift, skid plates, cd-player, little accessories, whatever your into.) Remember you dont need 1 foot of lift and 44's like others will suggest to go out on the trail. The wrangler can hold its own pretty damn well stock...

Where in North Dakota are you? I'm in Grand Forks, and i have an 03 Wrangler. I'm also running 235/75R15's, ( goodyear wrangler silent armors ). I've only had them on for a couple weeks, but i sure like them so far. I got a hect of a deal on them so i couldn't pass them up. Are you planning on putting a lift on? I think the biggest tire you can put on being stock is 31s. If you go to 33s i am sure you would need some sort of lift. If you can you should post some pics of your jeep, we would like to see it.

I'm in Minot. I have 2 sets of tires. Winter and Summer. The winter tires are studed Goodyear workhorses (235 75R15) and the summer are Goodyear wrangler at/s same size. I have a friend who just got 31's, but he's fixin to sell his Jeep because he works for the oil fields and is putting a lot of miles on it at 9-15mpg (depending on wind...he's also using the 2.5 L with no upgrades at all. He also bogs down the engine, 5th gear at 30 mph doing like 950rpm). I'm trying to convince him to swap me tires and I'll pay him a little on top before he sells it. I'll get some picture up soon. You know of any place to go offroad without farmers yelling at ya? I used to go to an old construction site, but they closed that down. I hear there's a good place in Velva, but I heard that from motocross guys.

Oh, if anyone has an 02 Wrangler with 16 gal tank, and is thinking about dropping the tank to cut the breather hose and make it a 20 gal tank...don't. They did it different for that year (or at least the X model). It's already a 20 gal tank. The breather hose isn't there to cut, and you have about 3 gal left after E. I'm not comfortable driving under E, but it's good to know it's there.

about the 20 gallon tank.. from memory the breather hose does not allow you to fill up more than 16.. so you do not have 20..... you have a 20 gallon that is allways only filled up to the 16 gal mark.

as the tires go. you can fit 32s underneath a stock TJ with some bump stop extensions.

I assume you have a 4.0 liter? I haven't done anything to the engine in my jeep and from all I've read, there is little you can do to get more out of the 4.0, unless you want to go the stroker route. Lets face it, you didn't buy a jeep for the 1/4 mile, and the 4.0 is not a high performance engine. If your planning on hittin the trails, you'll do better with things like; a suspension lift, bigger tires, and some undercarriage armor. Even the four cyl. are capable trail rigs if equiped correctly! The trouble with modifying your jeep, is that it's a slippery slope, it never ends.
