YJ build opinions. Please!

Hey guys! New to the forums and new to building jeeps. I have been messing with cars and trucks for a while and owned a yj once before. It was nothing special but it was very fun and special to me. Sooo I'm looking to build a new to me yj. I want something that can be driven 50 miles daily comfortably and still taken off-road very comfortably. I originally thought v-8 swap with a lot of suspension travel but have been led to believe that would be too much trouble for what I want. I would like to see any and all opinions on a daily driveable, 35 inch tire, air conditioned, fun mobile. Thank you guys for you're opinions and leniency on my noobness!

A V8 swap is a big deal. Before you get into any builds, you either need to have a big wallet or be good with a welder. That would be my first suggestion, get a decent MIG welder that can weld at least 1/4" with a 20' or 40' cubic cylinder of 75/25 argon/C02.

Engine swaps and axle swaps require welding, and most YJ frames will rot out on themselves.

For the air conditioning, it'll help your search if you're willing to get a manual tranny. I saw a video where someone said they had an automatic with air conditioning and that was only around 5% of YJs made? I may be getting the number wrong.

My suggestion would be to have another steady vehicle and buy a YJ with the 4.0L that needs machine work done on it. Look up the stroker builds, I hear they're pretty sweet, and they need machine work done on the engine anyway.

While the engine is being built, you can toss the rear axle, put in a Ford 8.8, and go spring over axle for lift. Put in an anti wrap bar in the rear, and over the knuckle heavy duty steering in the front.

Plus put an SYE in the transfer case, and custom order a driveshaft to the correct length.

I agree with MudMagnetYJ. Don't do the V8 if you want a daily driver, its fun to drive but it will be the basis for beefing up several other expensive components and it will add weight and most likely make your jeep less capable. The lighter you keep it the better it will be off road. It will also get better gas mileage.
If you want a daily good daily driver that handles decent then try to keeping it low as you can. If you go with 33's you can get by with a 4" lift and trimming the flares. Pick a lighter tire. The Toyo MT tires I run weight 84 lbs. A Goodyear Duratrac the same size weights 49 lbs. That will make a lot of difference in power to turn it and MPG. My YJ is my daily driver. It has AMC 360 and gets 9 MPG.

How you use your jeep should determine which route you go when it comes to your build.

Swap the seats. Stock seats are not that comfortable. Go with full suspension seats. Sprung under and 33's would probably make a decent daily driver. 35's add cost to the build. SOA can easily clear 35's. Do not expect SOA to be cheaper or easier. Include a steering kit from Mountain Offroad (MORE) for a SOA. Do not spend any money on the rear Dana 35 axle. Consider the Ford 8.8 upgrade. 33's may prolong the rear Dana 35. 35's will punish the factory rear axle.

I'll second anything said above. Seats are interesting though... I figured I'd swap out the seats but I'm a cheap bastard who doesn't care too much so I have the factory seats. I'd like a more comfortable bucket with a 4 point harness for trails, but I'm sinking money into my 8.8 build.

The main idea circling around here is don't mess with the rear axle. It's not worth pushing, upgrading, or anything. Swap it yourself or get an 8.8 from ECGS for a thousand bucks and change. They have factory limited slip.

Agree with all said, I like the Big Stroker Motor Thing, Make a long stroke 4.7 out of your 4.0 and have more Low end power where you need it in a JEEP!
