Oh, look, another LS conversion in a TJ. Yes, this thread is about another conversion, but I hope to alleviate and answer alot of confusion and offer some answers or advice. The goal with "Sarah" is to have a capable DD that can be very capable on the weekend. This project has taken a total of 5 years, and the shutdown gave me the time and motivation to finally finish her. Just 3 weeks ago I picked up the short-block from the machine shop, and as of last week I just need to add an exhaust and final tune.
There have definitely been alot of sweat and frustration, but in the end, I love the end result. Was it cheap - no. All of the 'small" items I did not figure in and found into the build added alot to the cost of doing this. The main factor was the LR4 I got. I thought is was pretty good. It came with a standalone harness and basic tune. As I started digging into the engine there was alot of issues and had to have the block decked, crank polished, cam bearings, etc - so a basic full rebuild. I estimate this added $2000-$2500 to the cost of the build.
This build though is very different than most LS conversions. I wanted to keep the NV3550 and dump the NP231 and add a NP241OR. I enjoy the experience of the 5-speed while driving, and I wanted something more robust and different crawl ratios than the 231 offered, so I went with a 241OR. I ended up finding a JK241OR with a 2-Low conversion. Also the main issue with the JK is there is no output speed sensor, as the wheel speed on JK's are at the wheels. The final part is the skid plate I chose, a UCF Zero Clearance Steel Skidplate. My combination, a 5-speed, 241, and the skid I found very little information on builds or information. With this I had to make major modifications to the shifter, and build my own transmission mount to the skidplate.
Also I tried to take alot of pictures as I could not find alot online. Visually seeing a object usually helps in answering questions with builds. I have included a link to the build for the pictures.
