Outer Limits 4x4 Board

Hi guys,
did a quick search but nothing turned up, so im asking the question.
I have a 4 speed g box in the 40. I have been told that they are stronger than the 5 speed, but the econ on the v8 is shocking. Im thinking of getting a 5 speed. Im not into any serious comps or anything like that, and i am wondering just how much weaker the 5 speed are if at all????

oh, and if any one is interested i just put some rear seats in for the kids, with added roll cage and a snazzy shade cloth top. ill put some pics up.

what sort of economy are you getting.. mine has the 308 and gets about 3.5 to 4.5 klms to the litre on LPG.. i dont even bother with fuel..

and show us the pics..

what 5 speed are you thinking of puting in it would be interested in some more info about it thanks

im getting about 5.5klm to the ltr. when not towing a trailer.
The box im looking at is from a later model 40, i think they came with 5 speeds.
I would like to do bigger trips now that the sprogs fit in the back and seem to like it.

I will post some pics as soon as i get some.

5 spds are strong enough.

late model 40s ones are just a 4 spd with a 5th gear attached to the back.

i run one of these behind my 383. its fine.

some people just abuse 5th gear too much. its only ment for cruising not accellerating.

i have a fj45 with a 308 . 4 speed 60 series box and transfer.
i run 3.7 to 1 diff gears insteed of 4.11 to 1 .
i get around 6 to 7.5 km/L .
with 33'' tyres it sits on around 2350rpm at 100km/h

i have some s/hand 3.7 gears if u need some .

4 speed boxes are as strong as the 5 speed boxes ./
it's the t/case u have to watch if u have a pre 8/1980 tranfer.
if u run a split type t/case they are alot stronger than the early one's .
