That last sentence should be your new sig line!
The plan at this stage is that I will do the SUMO Gears which are on the truck from @cruiseroutfit and then run the BJZ43 and see how it goes. Once I know if I am changing R&P's I will pull the diff's and rebuild them with or without a change. I have 4.56, 4.88 and 5.29's on the shelf and if I need to I will just try them all and find out what makes the 3B the happiest. Same with the Sumo's if I find the 4:1 with the 8% reduction in Hi doesn't work for me I will just pull them and swap to the 3:1 .
Yeah I will keep the 4.11 till I drive it. The sumo gears from
Interesting, thanks for the feedback, the bj60 would have been heavier to. This is why diffs will stay stock 80 till I drive it. Only ratio change initially will be th 4:1 sumo and 35's and I work work from that. I think the turbo will help a lot as well as the 3b usually suffers at higher speedsMy BJ60 has 4.11 axle gears, and 33s, so the speedo is really close to being back to stock. I actually regret swapping to 4.11s, as the 3B was happier at slightly less RPMs, and the 10% big tire overdrive was just right when it had 3.73s. I think you will be really happy with the 4.11s.
Yes, I was thinking that too; the 60 weighs ~6300lbs all loaded up with camping gear.
Mine is turbo'd as well. I have a 13BT manifold, CT26 and a top mount intercooler. I have the waste-gate welded shut and I adjust the fuel pump to manage the boost/EGTs/Engine temps.
Man I love it, nothing better than knowledge through success. I would never be game to wind up a 3B to 20 lbs but if it works more power to ya.Yup. I didn't say it was wise.
Its been running like this for years. The PO did the conversion and added the MLS gasket. I have bumped up the timing and turned up the fuel, and that is pretty much it.
. This is gonna be a fun one to watch! Godspeed.
I'd agree with you on the distance it needs to go back.Sweet, here is my other one which is my BJ46 , it always looked like the wheel needed to go back at least 5 inches

Have to love a 46. What is the measurement of the back of your wheel arch to back of truck ?I'd agree with you on the distance it needs to go back.
Here is my 1983 BJ46. Comes with A/C and 5 speed. Plan is to put HZJ75 rear end on with disc brakes, 15BFTE engine in there and do a full resto on the car while moving the rear axle back 4"-6" to get it looking correct. Will be painted in medium blue (857 I think)View attachment 2090156
