Greetings to all from the new guy.

I recently purchased my first CJ. I've always wanted one and finally found a great deal. It's an 84 CJ-7, 2.5L, T-176, dana 300, etc. all standard running gear. I rebuilt the motor and it runs great, just dissatisfied with amount of power. Can't afford an engine swap so I'm looking for any advice on increasing performance. Ignition, exhaust, carb., etc. It's in the 16-18 mpg range which I'm very pleased with as it's a daily driver. Would like to keep it up there but willing to sacrifice for power.
Also considering 2 1/2 "genuine suspension" lift and rs 5000's from 4 wheel parts. Good idea, Bad idea?
Last question is the ability to carry 2 Jerry cans and spare tire on rack. How are the racks modifieed to carry the cans or do you just have to buy a new rack?
Love the Jeep and already a huge cj fan.
Thanks for any advice,
Bwana

You shouldn't mislead him like that, every 6-8 month,s huh.
I bought my first CJ about 2 years ago and trust me, every 6-8 hours some new upgrade new will come into mind, every 6-8 days you will buy a part for that upgrade, every 6-8 weeks you will realize that you have to rethink the upgrade, and every 6-8 months you will actually have completed one upgrade and started about 15 other upgrades. That is the way it goes with me at least.

I LIKE KRISPY KREME DOUGHNUTS, Chocolate Crueler's look like little mud tires!

Welcome. I don't know much about Jeeps but this I can tell you:

1. I have the RS5000s and they ride a little hard, everyone recommends the RS9000s.
2. I have the 2.5 Skyjacker lift on my 85 CJ7 (I6 - 258) and it rides much smoother than stock suspension. I also have a 1 inch body lift and will be installing the Currie greasable shackles (which I believe are a little longer than stock). I run 33x12.5x15 and they don't rub (yet).
3. My wife is filing for divorce since I spent our kids college fund......
4. I've been looking at the Jamboree racks or Sport racks I think they call them. They go around and on top of the spare tire, they can also carry two jerry cans one on each side.
5. I don't know what to tell you about the engine upgrade other than I've seen some very capable four bangers on the trail. I guees good driving skills make up for the lack of engine power.

Good luck and one more piece of advice: fill out your profile, it makes it easier to recommend upgrades if we knew what kind of experience or terrain you plan on using your jeep for.

That's pretty good mpg's for a 2.5L. My YJ had a 2.5L stock with 4.11's. I got < 14mpg with 33's and a 5sp. I was thinking about the swap but, like you, wasn't sure about the $$. I found a junkyard that would buy my 2.5L and 5sp for $600, it ran but burned oil. I sold it to 'em and that bought my converter to the NP231! A friend gave me a tired 283ci to rebuild and I bought a TH350. Pretty soon, I was done and had a chevy V8!

As for putting more power into that 4-cylinder, ask TeamRush about a Ford TFI distributor upgrade. Somehow you can use a V-8 distributor and remove every other point, thus getting twice the saturation time and a heck of a lot more spark. The timing advance will seriously need to be tweaked. I thought I'd heard of a supercharger being made for the 2.5L engine too...both of these things will increase your power and your mileage, but you could probably swap to a 4.0L/AX15/NP231 set-up for the price of the Supercharger (after selling your old drivetrain, of course.) "Lower" gears will give you more power, but your speed and mileage will suffer. If you click on the picture below, you will be taken to a website on how to build this rack, which so far is the best one I've seen, in my opinion at least.

A can full of guinness. That's the best idea I've read so far. Wait a sec, How about two cans of guinness, as a bird can not fly on one wing alone.

Look up Clifford Performance. They specialize in four and six cylinder engines.

Have you looked here? http://www.off-road.com/jeep/tech/Engine.html

My brother and I have just pulled his 2.5L AMC engine out of his '88 Comanche and looking for a cheap and easy alternative (perhaps the 4.0).

Happy CJ-ing. Gotta get back to eating me Lucky Charms.

Just wanted to say thanks to all who put some input into my question.
Thanks, Bwana

Welcome, Bwana

Just a word of caution.....if you lift your Jeep, you'll probably want bigger tires, and your power will be even worse, as well as your M.P.G. Since you just rebuilt your engine, you may want to try to sell it for enough $$ to help with an engine swap. Maybe you should consider keeping it as it is at least for a while.....
