Hey guys, Little bit of a background on my build and why I’m asking the question in general. I’ve got an 02 TJ that’s about to have a 5.9 magnum, it’s got aftermarket front and rear bumpers, a winch, and a spare. I’m looking to go to a 4” spring in the front and 3” spring in the rear to mostly...

Hey guys, I'm looking to do a 5.2 in my 2002 Jeep TJ with a 5 speed, the factory motor is the 4.0 as it's a sahara. I know I need the bellhousing out of a dakota from a 3.9 but I'm wondering what are the possible vehicles i can get the 5.2 magnum out of that would make this swap easiest? I know...

Good afternoon all, I’m looking to do a disc brake conversion on my 02 TJ with the Dana 44 rear. Yes I understand that I won’t gain any braking power but I offroad my Jeep quite a bit and get in a lot of wet situations which drum brakes lack in which is why I’m making the switch. From reading...

Hi all, I’m looking to get some more power out of my TJ and thinking of swapping in a 318 instead of doing a 4.6 stroker since they’re like 12k for one from a decent company and was wondering if anyone has done this with an 02 TJ with the 5 speed and if the 318 would mate up to the nv3550...

Hi all, On my 02 4.0 TJ whenever I start it when it’s cold it’ll start at a normal rpm range but as soon as the rpm starts to go down it starts to bog, almost like it’s trying to heat up too fast and causes a miss, then whenever I hot start it it starts missing again until I start driving...

Hi all, So I thought I had solved my p0306 code with a new wiring harness that I got from deadjeep. It came with the harness that comes with the drivers side and the other harness for the passenger side. I just put in the drivers side because I figured this would solve the problem. It ran great...

Hi all, so I’m getting the exact same symptoms for a faulty purge valve with the p0443 code and a p0306 code and a rough idle and I believe this may be the problem. I pulled the vacuum line for the purge valve and this is what it sounds like. When I did this I also got the exact same codes that...

Hi all, so I’ve been dealing with a P0306 code for several months now and I’ve now reached the conclusion that I believe it’s a problem with the PCM and I need it either fixed or replaced. I’ve switched injectors #5 and #6 to see if the issue followed, it changed nothing, I’ve done a fuel...

Hi all, So I’ve been having this p0306 code for several months and it’s driving me crazy because I can’t find the solution to it, I’ve tried basically everything I can think of to fix this misfire code. I’ve changed the rail, I’ve changed the spark plugs and changed the #6 plug again to make...

Alright guys, I’ve tried everything that’s been suggested and still havent found the solution to my cylinder 6 misfire problem. 2002 TJ 4.0. I hear it at idle and feel it when driving as well. Did a compression test, everything looked good, did a fuel pressure test, that looked good, just...

Hi all, so I recently put a new motor in my 02 TJ and had to remove the passenger upper control arm(stock arms) to get the mid pipe out, but now the holes won’t line up to get the arm back in. I’ve heard of using a ratchet strap but where would you place it? Any ideas?

Hi all, so I’m planning on getting 3.5”(rock krawler) front springs and 3”(Rockjock) rear springs and have been doing research on Bilstein shocks to find the right ones and I remember on a forum that someone found a part number for some that have softer dampening. Anybody know which ones these are?

Hi all, I might be replacing my current motor in my 02 (nv3550) with a motor from another 02 but it was an automatic. Is there anything that would prevent me from being able to do this or anything to look out for? (Other than starter)
