Welcome to the boards 02TJ!

These are great questions, and it sounds like you're starting off with a plan, which is far better than just trying the old plug-n-pray method. ;)

If you're going to be doing a lot of mudding, then you're going to need lots of horsepower to spin your tires and keep them clean. There are a couple of ways you can accomplish this, depending upon your budget.

Most folks might immediately recommend changing your motor to a Chevy 350, which is what I've done every time, but there are other low-cost considerations as well.





The next few suggestions assume that you don't have to fight local EPA laws...

You can always put a bottle in your rig... A nice 50-75 shot of nitrous can give you that burst of energy that you'll need, or you can consider a supercharger, like a Whipple or B&M unit too. The nitrous will be the cheapest way to go, and the supercharger the second most expensive.

Your 4-cyl mill just won't put out enough horsepower to be an effective mudder, unless you do something like that. Cool air dams, free flowing exhaust, chips and the likes may net you up to 25 horsepower, but it just won't be enough.

If you decide to put something else under the hood, I would personally recommend going with a crate motor from Chevrolet. While you can go wtih a Dodge or Ford motor, you will be hard pressed to find good support for conversion kits, wiring needs, and personal support from others who have done the same thing. There are two companies (Novak Enterprises and Advance Adapters) that make engine conversion kits for your rig. If you do this, you're going to have to change most of your running gear (e.g. transmission, transfer case, and axles), as the stock units may not handle the horsepower that you can feed it. While this sounds like a real drain in your checkbook, you can source everything from local salvage yards for about a 1/3rd or a 1/4th of the price and rebuild them yourself, saving tons of your hard-earned cash.

You're also going to have to consider tire size and tire type as well, and if you want to go with anything larger than 35" tires, you'll want to consider changing your axles as well, and perhaps your transmission.

Regards, Rick

thanks for the reply rick, i actually have a 318 with an automatic transmission i can get for free (thanks dad) which is an extreme help money wise, however i know kits and adapters are a lot harder to find. i'm a little more flexible with the transmission to get something easier to adapt to a transfer case etc. i plan on keeping it stock to help keep the costs down. i really don't plan on more then five inches of lift because i plan on using it as daily driver to work and the store etc. as far as wheels and tires i'm not sure what would fit a 4-5inch lift. also any other advice would be great. thanks ken

i agree chevy is much easier to adapt....but there is more options you might consider goin with a 4.0L if you ain't lookin for huge power trannies are easier to find and less conversion pieces....if you want a lil more power and want to keep it simple look at the 4.6L inline six stroker motor more power without all the hasle of finding adapter parts you might even get a lil better gas milage since it is your day to day.....i know a free motor is a free motor but i have had a few buddies with the 318 and i am not a huge fan they are loud and sound good but don't make a lot of power and chug fuel. thats my 2 cents
