I don't have a thread on it. I bought my MJ new off the lot in 1992. It was the "Eliminator" package. I drove it 23 miles home and started modifying it. Right now it has over 300k+ miles on it and has been through numerous mods & revisions. Here's the current state of affairs as I can recall:
RE Extreme 6" lift front (hate this, very noisy)
BFG M/Ts 33x10.50x15 on factory rims
Custom spring over rear suspension
High pinion Dana 30 in front with 4.56 & ARB
Dana 44 in rear with 4.56 and Detroit locker (killed two 35's & three ARBs)
6" drop Pitman arm
Currie drag link
TJ bell housing with external slave cylinder mated to original AX-15 5 speed (lost count of # of failed factory slaves in original housing)
RE sway disco (hate this too)
Autorotor twin screw super charger with intercooler
Custom fiberglass hood
Split Second programable MAP sensor
50% larger injectors
Folley header (cracked 2 Borlas & 1 factory before this)
Flowmaster muffler
Safari Snorkel
K&N air filter
Warn 6000 with Winchline synthetic rope (need to upgrade to 9000)
Modified Warn winch mount
Custom All J rear bumper with integrated class III hitch
Custom made false bed
Snugtop shell with side doors & rear glass hatch
Four Hella 500s mounted on Conferr rack
Fiamma F35 awning mounted to rack
Electrical mods too numerous to name...
If you're seriously considering doing up an MJ and you need a sounding board, I am happy to share my experiences. My Baja Burro, as I call it, has been a trusty companion. Never has it left me stranded. Here's a recent pic.
