Yes, JB makes a SSYE like the one i linked with no VSS, seeing how your adapter eliminates the issue with 4lo and the speed the computer thinks its supposed to see makes for a cleaner, issue free conversion, Im probably going to go your route, but with a SSYE with no VSS (or a Jeep VSS and run my speedo off it), and your Tcase adapter.

Harness issues...

It's a nice piece of metal. One piece, one solution.

I was going to install the wirng harness today. When I laid out the harness, I notice it had two rear O2 sensors. It should should only have one, since I am running single cat and exhaust.

I anticipate sending it back tomorrow...

I have until the 21st to get this thing running. There is an anual run up to Camp Verde, I don't plan on miossing it!!!

That is so you can be emissions compliant, if they made your harness to be complaint, you need 2 cats...
The cats on the 5.3 arent too big either, if you have emissions inspections, you might want to squeeze them in.

I spoke with Novak today, it sounds like my harness will work fine as is. I am going to run both post-cat sensors behind my single cat. I guess I will find out...


The wiring harness looks great btw! All new looms and everything is marked clearly.


I will be firing this beast up by the weekend!!!

Intake

I stopped by Airaid today and picked up some tubing. This is REALLY nice stuff! I got everything in the 3,5" size. It worked better for getting under the gadiator hose. I had to stretch a 3.5 coupling over the 4" intake, but it worked great. Also installed in the inline MAF sensor.

Thanks to Mark at Airaid for taking car of me!

I found a radiator hose to kind of fit. It wil lwork for now, but I'm worried about it rubbing on the intake. Time will tell.

The Lokar cable shifter is done being mocked up,. I just painted the new floor plate I made for the shifter tunnel. I will finish it all off tomorrow night. I plan on doing the wiring harness too. Novak did a good job of labeling everything. I think I can figure it out...

Go for it! This really has not been that hard of a project. There is lots of information out there on the swap. I started the beginning of February and only worked on it Saturdays. I put a couple of weeknights work in, but not many.

It should be worth the work!

Wiring harness

I got most of the wiring harness installed last night. I still have to mount the ECM and run those connections. I also have the 7 wires to tie into the Jeep to do still.

I have always heard that the AX-15 will hold up fine behind a mild V8. Same with the NP231.

But I'm gonna spend 300+ to adapt to it, I think then if it blows up I got a 300+ adapter I can't sell I can pry get gm drivetrain for that, but I want to retain the 5 speed (kinda got a throttle foot some times so I'm questioning the durability of the ax14) lol

OR, you can buy this:

nv 3500 5 speed and np 261ld from 2002 chevy

I might... trying to find a way to replace the 261 with a manual shift tcase that I can drop SSYE into....

Persaonally, I would not run the AX15 behind it. You will eventually break it. Just replace with a GM transmission, it is engineered to handle the power. Your 2.5L puts out about 140 pounds of torgue, MAX. A 5.3L motor will have over 200 pounds of torque sitting at idle. Thats quite a difference!

The NP231 will hold up fine.

Shirfter pics

Here are some pics of the new Lokar cable shifter and the t/c case shifter from Novak. Both were pretty easy to install. I had to fab a new tunnel cover and still looking for shifter boots to work.

Today is the day!!!

I have the wiring harness hooked up and ECM mounted. I put the ECM where the washer fluid bottle was. Seems like the best place for it, and thats where the wiring harness will let me put it...I will have to relocate that bottle.

There is still a bundle of wires that I need to splice into the Jeep system. I am going to make those connections today, I hope I can figure them all out.

My goal is to fire it up TODAY!

I'm currently in the middle of a ford v8 swap into my yj.

I tossed around the idea of running a ax behind the v8, but decided to go with a ford truck 4 speed. After my cam and head work, I'll be putting down far too much twist to use any jeep trans. I have heard that the chain driven tcases are questionable behind a powerful v8. You can probably find a dana300 out of the older jeeps with the twin stick capability. It will be your last tcase for sure. Those things are pretty bullet proof.

I read the first few pages, then skipped to the rear.

What are your plans with the differentials? Are you swapping them out? I'm swapping my rear out for a ford 8.8, but not sure what I'm going to do about the front. I was told the 30 out front with a vacuum delete kit will be okay. But then again...I'm nearly tripling the factory torque specs, so I'm a bit hesitant to keep the front end.

What are your plans?

I have a set of Waggy D44's in the garage. I plan on having them re-geared, ARB lockers, and going SOA. If you get the right Waggy axles, they are the correct length and have the driver side drop in front. I THINK mine came of an 88 Wagoneer.

It was right around $650 for the Novak set up. They did a good job with it, new wiring looms, reprogrammed the ECM, and everything is labeled clearly. There were a couple small issues with it and it took longer than it should. Overall I am happy with Novak and their products.

Wow....$650!? That's insane.

Cool man. Doesn't sound like you were worried about cost during this swap lol.

Everything looks real good though!

Thanks Collin. I really hope it fires up today!

I was worried about the cost on this project. However, I believe that you get what you pay for. I only wanted to do this once, so it was important to get it done right the first time. I shopped around and there are good quality alternatives that cost less. In my case, I felt I was paying extra for the expertise of Novak. SO FAR it has been worth the extra money.

Today will be the test! In fact, I'm getting off this computer to go hook up the last few wires. Hopefully I wll be posting a video of the beast firing up! It only has headers on it right now, should sound awesome!

Did they make it a stand alone harness that only takes two wires to the ecu to run?
