I haven't updated my A750 thread, but from talking to lots of folks about my slippage & gear change issues, new valve bodies don't necessarily fix it. I will update that thread for consistency, but the latest advice I've been given is to swap the fluid and then add 1/2 bottle of GM limited slip diff fluid (which amounts to about 4 ounces.
Im really just hoping it will cope with all the extra weight added down the track. I looked into diff gears but they are just two expensive for me

Actually while we are on the diff ratio topic, if i was to fork out for diff gears. Nitro, yukon or revolution and would 4.56 be too much for 33.3 ow 33.8 tyres?

I've been a long time Nitro fan. 4.56 should be good for that size. You can compare gear ratios here...
In the first drop down box select the Toyota A750E and then in the second drop down plug in Tacoma and FJ for the tcase.
You can skip step 3, and go to step 4 for diff gears
After that it's all about tires.

Resulting stats will show RPMs and speedo readings.

Ye i have messed around with that, at 100kph (63mph) on 33.8s i was going to Be at 2056rpm, not sure how this will effect fuel economy. Dont want to drop it down to low and be chewing the juice

So on the topic of gearing, has anyone looked into a lower ratio gear for the transfer case (just the highrange) would be far cheaper then rebuilding two whole diffs and have the same effect as re gearing the diffs

Wouldn't be practical. High range in any Toyota transfer case is just a straight pass through, 1:1. Redesigning and manufacturing new transfer case gear sets would be way more expensive and a lot harder than re-gearing the diffs. Almost impossible for the FJC anyway, because the transfer case is chain-driven.

Now if Marlin Crawler would produce a lower 4Lo gear set, that might be worth looking into ;)

Quick bit of wiring last night red arc dual sensing battery isolator, this one allows the solar panels i use camping to charge both the aux battery then after a certain voltage is reached it allows the start battery to be charged aswell, same goes for if i have a 240v charger hooked up.

Can also be overriden to jump start.

So one of the companies that does supercharges here for numerous cars including fjs has recently starting tuning n/a 1gr engines, this is 95 octane on stock car.

Their first tunes were 91 and included a comparison between stock and removing the restriction from the airbox inlet which gave them another 15hp over stock.

Ill be running their 98 octane tune with airaid intake and full exhaust, hoping to push 250hp on stock size tyres
