I just need to get back to work on it and on my new job. I have what I need now.

Tore the old trans and transfer out. I am currently rebuilding the transfer case and putting the 23 spline input gear on. Case is split waiting on more tools.

On a side note, this transfer is so cool, it has an oil pump.

On a side note about AAZ / TDI in a Jeep.  I have a project putting a Mercedes 240D engine in a YJ, and another 4BT already in a 68 Bronco, but I have always wanted a diesel in a CJ2 or CJ3. For sure the YJ would go bye-bye if I could put a diesel in a CJ2.  8)

Think the AAZ / TDI would be perfect for the Small CJs, but there are no T90 adapters out there, and the 134s are actually putting out near the same torque as the AAZ without mods.  I know an AAZ or TDI would be perfect for those little jeeps especially with the Transfer overdrive.  Not much room for a longer transmission than the T90 or T96, so options are limited.

Anyone know of a T90 adapter?   ???

Haven't updated this in a long time.

I acquired a 1.6 engine for putting this together as soon as I can. By this time next year I will have the mTDI in it...if it all goes to plan. Right now the jeep engine is out, trans, transfer, driveshafts, gas filler, and center console are out of it. Since the TJ are so bad to frame rot and I am most of the way there, I am going to pull the tub off, sandblast the frame and bottom of the tub, then rust bullet it and put it back together. If all goes well I will have it by this fall.

Gas tank is out...busted the fitting on the output of the tank. I found out it has 4.11 gears and the dana 35 axle setup. I wished it had the low gears but I didn't want the weakest drivetrain they put in them. I am hoping that it holds up, if not it will get big axles in the future.

I decided that now is the time to rust bullet the tub and frame. Next time I pull the engine I don't plan on pulling the entire drivetrain and to pull the tub off to rust proof and that is what is needed to be done. Here is what it looks like:













After looking at the pics and verifying outside, the sway bar links are trash. Completely torn in two. I am looking into building my own that I can disconnect with the pull of a pin. Will probably use this site for bearings I can hopefully weld on, see if the high temp really means it.

I have huge updates, but not any pics yet. I worked on the Jeep instead of taking pics...I sandblasted for about 7 hours and Rust Bulleted the frame. The body and frame are separated and almost ready to be put back together. I want to fix the body bolts I broke off and then lift it back on. I haven't looked at what a Jeep weighs but the frame and axles are very light compared to what I thought they would be. I would guess the body is heavier than the frame and stuff. Furthermore I think it probably weighs less than the MKIV Jetta, but I didn't have seats or anything in it, so maybe not.
I was one tired guy after this weekend getting all of that done. I will take some pics when I go and put it back together, you just won't see any before and after shots

Good to see things moving along. You might also look into Waxoylhttp://www.waxoyl-usa.com/Products.aspx?code=WAX-001&key=cat for inside the frame if it is a box frame.

It is definitely a box frame, and I like the idea of that. Trick would be getting it in there. I put a 1" body lift on it so that I can access the frame better to wash it out, so maybe I will do this.

A lot of people use a garden sprayer, the type you pump up, and a long wand to get inside holes of the frame. Some people also make their own solution from wax, oil and white gas.

Anyone have ideas on how to hack the fuel sender up and make it suction only? I busted mine trying to figure out how it works. I also busted the regulator when I dropped the tank. I haven't found a Jeep TJ to carb SBC thread anywhere, but you would think there are people out there doing it???

My jeep diesel swap, I left the in-tank pump alone, put a fuel pressure regulator on the supply line, and regulated fuel down to what's needed for the diesel. Then needed to run a second return line back to the tank from the regulator (meant for the excess fuel to go straight to tank, and not backfeed into the oem return line).

I used an edelbrock fuel regulator to get from 60-80 psi coming out of the wrangler's tank down to my desired 5-10 psi at the engine.

I figured there was no way the stock fuel pump would last cut to less than 10%. I have a solution now, so all is good, but let me know how yours does as if it lasts I would much rather leave the pump alone.
