I'd hate to make a recommendation on something outside of my realm honestly. I think Uplifted on here has a SBC backed by an AX15 and he's had good luck with it.

If your wanting the the 5.2 why not find a 2nd gen ram donor for the engine trans and transfer. I would think that they would be a pretty cheap option pull what you want off of it then part part out the rest to help recoup some of the cost and sell the rest for scrap.

ok after a lot of careful consideration and a buttload of reading i'm aiming for a different setup. A much milder setup, let me know what you think

Engine: 4.3L Vortec. I'm going with this because it should have plenty of power to move 33's, enough power to cruise up to 90ish if needed, and should yield excellent MPG.

Tranny: Probably just leave the stock AX-15 and an adapter from Novak, plenty strong for the 4.3L even if it's tuned or built. If theres ways to beef it up anyone let me know.

T-Case: (Thanks to goose) NP231, seems to have the reputation i need. and quite compatible, and will most likely come in the jeep i Buy or not hard to find and put in after.

Axles: ehhh still not sure, ford 8.8 is starting to look better, I just want disc brakes for the 33" tires. and after looking at goose's thread, i'll be doing an SOA for my lift.

input?

If your going to go through the trouble might as well keep it a V8. Try the vortec 5.7

fuel efficiency my friend, as long as I can get it up to 90 when i need it, i wanna get the best MPG possible (yes i know i wont get anything spectacular) but if the 4.3 is powerful enough to move the rig quick, i wont need a V8.

This is a suprise to most people. But you can actually get better gas mileage with a fuel injected V8 in a jeep. Think about it. One fuel injection is much more efficient. Two with that V8 moving the jeep its barely working so it doesn't need to burn that much gas at all. With the 2.5 and other small motors your either revving really high sucking in gas or your lugging it along working it to death using more gas.

This is argueablly a good example. Corvette Z06 has the LS7 in it. Pushing loads of power. It gets 29 miles to the gallon. The trick is to keep your foot out of it. But you have to have the proper gearing for your transmission and tire size as well.

Yjkid I don't know about 29mpg on a Z06 it's got 505hp and is rated at 22 city 24 highway. I doubt 29
That's not the case with all V8's about not working so hard and all of that, it depends on your gearing, gearing helps keep your RPM down or keeps it really high depends on your gears personally I think you should get the 4.3 make sure it's a vortec it should be get a 700R4 transmission it's got an overdrive. It is an auto but you mentioned you want overdrive. Or just keep the AX-15 and get an adapter (great tranny) the ford 8.8 is a great axle choice comes with 31 spline shafts and you can get it with 4.10's and a limited slip (4.10's will be great for you with the 4.3 and 33's) as for the transfer case the NP231 has it's breaking points but is strong as well and if not that case find one out of a 03 and up rubicon (4:1 ratio I believe correct me if I'm wrong) as for that Smittybilt stuff, look into it a little more ive read quite a few places that their paint comes off easily, don't take my word on that though as I myself am buying a couple minor things Smittybilt, get either a warn winch or a superwinch not smitty I know it's budget but smittys winches aren't that great. There's been quite a few problems with it, also with the ford 8.8 out of the crown Vic I think that it's coil springs? But that's just what I think :P budget is nice but so are quality parts even when the bill is not so nice. I personally fabbed up my own bumpers, really heavy duty and all the metal is from the US, oh and the SOA can be alot of work, driveshafts slip yoke eliminators make sure you read a thread that goes into full detail because an SOA isnt to be taken lightly and If I were you, when you do the SOA I recommend you create a support that will prevent axle wrap.

When do you ever need to 90 in a jeep? You also don't need rear disc brakes with 33s. They are nice, but most certainly not needed.

well I am a speed demon, my current car is a V8 S4. but either way being able to do at least 90 i don't think is an unusual request, sometimes you're in a hurry, or on a road trip and wanna make good time. I'm not trying to be the fastest jeep just fast enough to get things done.

and as far as disc brakes go, umm yeah i would prefer them over drums, even with all the other pros, its a safety thing. bigger wheels and tires need better braking, that's rather simple

btw where in NE ohio are you? i'm on the westside of cleveland

I agree with the disc brakes much preferred, not need but preferred, but I'm sure the speed limits and a little over can get stuff done for you fast enough man, perhaps you should leave to high speeds to the S4.

im not saying ill be tearing up the road, just want the ability to push it a little when needed, but yeah i'm a huge believer in brakes are the most important part of your car. any idiot can make a vehicle go fast, but if you can't stop it in time, you're dead.

you should see the brakes on the S4, too bad it's being sold

as far as the SOA goes, i've been reading like crazy, as you can see i originally planned on a 4 inch spring lift, but the advantages of the SOA have lead me that route.

as far as smittybuilt, thanks for the input, I havent taken the time to really look into quality, all that will be done after i nail down the plan for the drive train

Just a heads up,,, I saw you mentioned earlier about using an 8.8 from a crown vic.. You need to be carefull on this... The car 8.8 has thinner wall axle tubes and the diameter itself is smaller... Car 8.8 specs out at 3" diameter tubes and the truck 8.8 is over 3".... I have a taxi cab account at my shop and they use all ex police/ detective cars.. I have swapped out three 8.8's so far that have split the axle tubes clean through. These were never in an accident either. They were just driving along and suddenly boom, the tube snapped.... I strongly suggest you use an 8.8 out of an explorer instead.... Other than that it sounds like your going to have a nice YJ... The 4.3 is a nice engine.

Damn. Definitely noted thanks man. The only reason I asked about the crown vics was because I wanted a wider stance, and unfortunately the explorer actually shortens it. I guess ill just have to use spacers.

You want the wider stance pick up one out an F150 someone already mentioned that it's wider than the Vic and stronger.

ok so lets plan for the 8.8's front and rear. how would you guys go about setting them up with lockers n such? mind you this will be driven on the road mostly, and not incredibly serious off roading, also I will certainly need traction in the winter time. And will it come stock with 4.10 gears? cuz that seems to be the best thing for MPG

If as you say it's primarily going to be a street driven jeep then search for a 8.8 from a later explorer that was a v8... They came with a 4.10 gear ratio, disc brake and factory LSD (limited slip differential).. Mine was from a 98... The factory LSD will give you all the traction needed for the street and trail and alot easier on the axle than a locker would be.... JMO

^^x2. As long as you dont plan on lifting wheels of the ground while wheeling a limited slip will do you justice. As long as its not to worn. My brothers LSD in his ranger is just about toast from burning out, drifting, fishtailing, romping on it basically. And now its starting to do one wheel burnouts.

I don't know how easy it would be to set up a 8.8 in the front... but from what I know the lsd and 4.10 gearing wasn't standard but just options thehe 4.10 only came in the towing packages I believe and lsd I don't know how common they are but can be found in some just check out the axle before you buy

I'm pretty sure the LSD was standard on all v8 equipped explorers... The gear ratio was in options...3.55, 3.73 and 4.10's

The one I am using is an open 4.10 out of a 2000 V8 explorer. The open diffs are more prevailant than the locked ones.

thanks guys, I'll be on the hunt soon as the deal is going thru on my S4.

I'm in no hurry to get this thing done so I can take my time getting the parts n such.

Also I have an idea for removing the hard top, my version of the lift in the magazines.

Putting 4 eye-bolt screws thru the top to a metal plate to spread out the load, and grabbing one of the 1000LB winches from costco (70 bucks) and bolting it to one of the beams in the garage and using that to hook and lift the top off and on.

what do you guys think?

Sounds good... Take it one step further though to avoid the unsighly eyebolts that will be sticking out of your top all the time..... Weld nuts to the metal plates instead and glue them up on the inside of the top.. Then when you want to remove the top you can just thread the eyebolts down into the plates and when not in use you can simply make threaded plugs to fill the holes to keep it water tight and not stick up like the eyebolts would.. Just a thought..
