Wow, those do look great! Ever done a comanche? I would love to have one with an airbrush of my truck on it

I saw a 92 MJ on ebay a few years ago, 4.0 4x4 5 speed, low miles, exactly what I wanted, but I was only 15 and my parents wouldn't front up the cash for it and the trip to MA to go get it since I was, a jobless 15 year old. So I painted it, what do you think?

Man, I wish I'd know that a few years ago....my cable hadn't snapped, but the little plastic thinger wouldn't stay in the bracket at the front of the hood. I left my lights on at work once and couldn't open the hood to jump it. So we utilize the crack in my header from when I hit the dear and...yeah. Used to be what my driveway looked like when I lived at my dad's. 1 1/2 of the blue ones are gone. The rest of the one on the right is in my shed, or attached to my MJ

I totally agree, V8 would weigh more and therefore bring your front end down. Problem fixed!

Physically it should drop right in, motor mounts will be the same, your old manifolds will bolt on, but if the new motor is an HO, you're probably going to want the HO injectors and get ahold of an HO exhaust manifold, they're header style, and much better than your 87 one. Everything on the front of the motor, i.e. alternator, PS pump, water pump, fan pulley should all bolt the same way. *I'm assuming your 87 is MPI and not TBI Another thing is wiring, the 92 and 87 manifolds used completely different throttle bodies, I don't remember if the plugs for the TPS and IAC are the same.

I think .010 will be good, since I can't do the machining myself and I'm practically having nightmares over what it's gonna end up costing. Without purchasing a crank or machining, or anything to do with finding a tranny, I'm at about $1200 right now. BUT, if you give me a rebuilt Ax-15, I promise I'll bore to 4" :brows: On a seperate note: While I'm not a fan of the 4 door wranglers, the new Jeep commercial always makes me laugh when the truck goes up the snow halfpipe.

Should just probably point out, don't know if you know, but only the front doors from a 4 door XJ will work, the two door ones will not.

Yeah that sounds about right, .010 over pistons are the same price as stoke so it shouldnt be a problem

Wow, I didn't expect so much so soon, you guys are awesome The motor from the 92 is an HO, so the injectors would be the HO injectors. Also, since I'll be having the cylinders honed, would it be a good idea to just bore it out anyway? My dad just happens to have a 91 XJ with the 4.0, so with any wiring I should be able to just make sure it looks just like his, right? As far as I knew everything in the engine bay between an XJ and MJ of the same year and options should be identical. Except he has AC, Cruise, and power locks/windows, wiper delay, I do not have any of those. The 92, the donor of the motor, did not have Cruise or PW/PL. With stroking, camming and maybe boring it out, the computer from the donor 92 should still be useable, right? I know it's a lot of questions but I want to get this done right.

My truck's just a 4 banger 4 speed right now, but I'm planning and dropping 4.6 and AX-15 into it soon, only thing holding me back right now is the money. Right now, I have a 92 4.0 from a scrapped XJ that still runs but it would be a good idea to rebuild it before going into a vehicle, so I might as well do the stroker. There was an AX-15 with it, but my brother accidently sold it (long story) I also have the complete engine bay wiring harness and Computer from that truck I have found sources for almost everything I need; Gasket set, Rockers, Pivots, Push Rods, Lifters, Cam (aftermarket from Summit.com Crane# CRN-753905), Cam Bearings, Timing Set, Main Bearings, Rod Bearings, Connecting Rods, Pistons, Rings, Dist Cap and Rotor, Oil Pump and Strainer, and Headers. Haven't gotten ahold of a 258 crank yet, or any machining estimates. Otherwise internally all I think I need to find yet is valve springs. I'm sure a few out you guys out there have done this build, is there anything I need to know about it? i.e. I know the snout on the 258 crank will need to be machined down. Can I use the injectors from the XJ's manifold? With needing the crank machined will I need oversized main bearings? Going from the 4 to 6 cylinder, will I need to worry about any wiring other than the injector harness? What color should I paint the motor? Where can I get a good price on an AX-15? Can I put the T-case from that's attached to the BA 10/5 from my 88 XJ onto the AX-15? Thanks for any help!

Buy a rebuilt motor, and *poof* unfroze pistons
