    TJ de-computerization help

    I've got an 03 Sahara TJ with a 42rle and SKIM, I want to do a manual swap but the SKIM system is making it a pain in the ass. On top of this I dont like the idea that (no matter how robust and reliable they are) computers are running my vehicle. Ive been thinking of doing a carb conversion for...

    Engine swap ideas

    I’ve been reading a lot about swapping an engine and I’ve asked a lot of people about swapping an engine. Some people tell me to go all out and swap a 5.7 Hemi into my wrangler and others tell me to put a 4bt in my wrangler, even going as far as to say a kubota and I’m just wondering what you...

    Engine swap '98 Sport to '99 Sport?

    Hey everyone! I just picked up a '98, I6 5spd, and it turned out to have a pretty screwed frame. I was wondering, if I were to buy a '99, found one for cheap with a blown motor, would the engine just bolt right up and plug in? Both have the same engine and transmission, was just checking to make...

    06 TJ Engine And Transmission Swap

    Hey all. So I haven’t seen a “master” thread that answers a lot to common questions I’ve seen/ I have myself. I’m looking to engine swap/upgrade from a 2.5 to a 4.0 in my 06 TJ. From my original thread, I wanted to do a complete swap from a 99 into the 06, but I’ve since seen better options...

    Another Jeep was running, then wasn't running thread

    So I got my project TJ of almost 3 years running about a month ago. Since then I’ve been ironing out various things here and there (mostly steering and ride quality issues). I’ve put about 300-ish miles on the engine since the swap. Today I readjusted my caster because it was off from swapping...

    Engine and Transmission Swap (97 to 06)

    Hey y’all, So I recently purchased an 06 that has a blown engine, it was being towed behind an RV and popped into gear. My first question is, what is the extent of the damage done to both the engine and transmission? My second question is a little more technical. I have a 97 with a 6...

    Let’s talk about TDI diesel swaps

    Has anyone done a 3.0 TDI diesel swap into a TJ? I know the smaller 1.9 TDI has been done and maybe the 2.0 TDI. I’m not finding anyone with a 3.0 TDI swapped TJ when I search the web. Surely someone has done it by now?

    Thoughts on power upgrades for 2006 TJ 2.4?

    Hi guys. To say the TJ 2.4L is underpowered is a severe understatement. In the wind, on the highway, a slug. Just a fact. I’m the original owner, have taken good care throughout. Been told by several trusted mechanics it's in unusually clean and great shape. Current specs: - 91021 miles on a...

    2006 2.4L Engine Replacement Worthwhile

    Hi all, I'm doing some research on replacing the 2.4L in my TJ. I'm at the end of nearly a year and a half saga of my jeep cycling between drivable and not drivable. At first I was having overheating issues, then the engine started blowing oil out of who knows where that the mechanic couldn't...

    Project: Probably Shouldn't Be Alive AKA Sue

    Starting in about 2018 I was desperately looking for a project. My friends and I had been on a University Baja SAE team, and after finishing college one of my buddies decided to make his own, more powerful Baja car. While that project was going on I figured it would be nice to have a reliable...

    Swapping a 2006 4.0 into my 2003 4.0: What can I expect?

    I plan on swapping the 4.0 in my current 03 Wrangler for a 2006 4.0 and was wondering what to expect. Mainly, I've heard that the ECUs are not compatible. Some sites have said I'll need a full drivetrain swap, others have said a custom TCU. Hoping to get a definitive answer here. Thanks!

    New skid plate not lining up with frame holes

    Doing a UCF skid with my engine swap and even after pushing the 5.9 as far back as possible to weld the engine mounts in I knew the trans was still about 2" further forward than the factory position. On the upside, that means I get a little more rear drive shaft length which I'll be needing due...

    Minimum driveshaft lengths

    I know this isn't exactly a straight-forward answer, there's a lot that goes into it. So, I'll start with the basics and you guys can give me feedback and I can fill in the gaps on anything I didn't specify initially. My Magnum V8 swap is nearing an end. The past 2 days have been spent...

    Missouri Need a good shop in the St. Louis area

    I have a 98 tj that I have had since college. It is the 4 banger AND it is automatic, so it is basically gutless. I have done everything I can to squeeze what little power there is out of it, but it is time for a new engine (the thing is old enough to drink legally now). Now, before anyone comes...

    North Carolina NC engine swap laws

    i'm looking into doing an engine swap and am currently looking up all the legal stuff. I've found a lot of opinions about NC engine swap laws and on an official website, it says to refer to this EPA law as the law for my state. https://www.epa.gov/sites/production/files/documents/engswitch_0.pdf...
