Friend has 1990 80ser cruiser with 3F engine, that has blown 5speed g/box, been offered g/box out later model criuser with 1fzfe engine. will the later model g/box bold up to the early 3F engine? or if not what is the difference. If not chasing an original 5 speed to suit. Contact on here or call 0429924755.

to my understanding, no , however there is model numbers on the boxes in general.. h151 etc stuff like that.
also internal ratios change between the various engines. ( 1hz, 3f, 1hdt etc etc )
Bell housing also change to suit the engine

you can change the bell housing over you will have to change the clutch as well as the input shaft is different spline. not sure if clutch will bolt up with fly wheel though

what has it blown? if you get the parts, you can do it yourself for quite a bit cheaper.

i thought my h55f that backs my 2h was gone(turned out to be the diff had blown massively) seals and bearing come to just over 800, (kit had seals bearings a shaft and gaskets) that was for both transfer and gearbox, so if the 3f in the 80 didnt use the h55f and same transfer as the 89 75/60s, you might not have to replace the transfer stuff, and there fore cheaper, gearbox kit was just over 400, the transfer was under 400.

that was from terrain tamer, they said that syncros dont cost to much, and i have been told if you need gear sets to go to the wreckers they usualy split them up and keep them, and they arent to exy either

also, best to crack it open, then you will know what you need, that way you dont go buying stuff you dont need

many cruisers share the h55f box. Im pretty sure my 1fz-fe has a h55f as mentioned above check part no's

The FJ80 had the H150F gearbox, just like the HZJ80's, but the bellhousing will be different and possibly the imput shaft too.

FZJ80 and HDJ80 had the H151F, only difference is that ratios of first and 2nd gears respectively were taller than the H150F, and the input shaft is bigger.

No 80 series had the H55F.

The input shaft is shorter on a 3f and the bell is shallower....so to get a 1hz fz hdt infront is a PITA not to mention each have a different spline to the 3f (which is thesame as holden v8), to change the input shaft, the whole box has to come appart, you could possibly space the bell or box to correct the length issue and find a clutch plate suitable for new spline and clutch plate OD, but it is a lot of hit and miss...
