100 ser gearbox swap

It doesn't have to be later model box, the T/D and 4.5 petrol in the 80 series is bigger than what you and I have got.
I think they have a higher 1st gear and slightly different ratios through out all the other gears (except 4th) but no-where enough difference to warrant a diff change.
I don't think ANY alterations are needed with fitting but not entirely sure.

AFAIK, you need to change bell housing, flywheel, clutch and gear shift levers.Transfer case will fit off your old box if needed(may need one shaft changed).
You have the "R" 151 box and need to look for a "H"151 or "H"150 from an 80 series.

Best place to look for this information is:

LCOOL forum

Go to the 100 series section and enquire there as there are many on there who have done both engine and gearbox conversions.

The above post that mentions the R151 and H151 gearboxes is correct, but there is a few variations on what bellhousing, input shaft, and transfer case linkages may be required to avoid cutting extra holes in the floor.

I will watch this space as I'm interested also........

Please let us know how you get on.

Ok the box and transfer from a 4.5 petrol 100 is the one to get. If you were to buy an 80 series diesel box and transfer, it would also be good, but get later than 95 as the early ones had synchro problerms. The 80 box will also need a 100 shifter, hence the 4.5 100 box is better....you then need a diesel (turbo or 1hz) 80 or 100 series bellhousing for it and an fzj75 clutch plate to fit in the 1hz pressure plate.
1st, 2nd and 3rd are higher than you have, 5th is lower. You will be doing 2700rpm in 5th at 100 km/hr but it wont break.
