LT77 Dsco box into a 90

[BK]

My gearbox/tranny box on my 200tdi disco powered 90 is about to go into the land of dead gearboxes(wherever that is!!!)and I have chance of a disco lt77 box and t box from a mate,does any one know if it will fit my 90 or has anyone done this before? answers on a postcard please :lol:

i think the gearbox is longer for a disco than a defender, but if you have put a disco 200 in it what gearbow is on it anyhow?

its the original 2.5 td lt77 gearbox/t box which is just about goosed

i have this set up on my comp truck, luck for you its in bits atm so can take plenty of piccys for you  ;)
right
the bellhousing is longer on the disco box for a start, so you need to move the engine mounts roughly 5 inches forward IIRC ( which conveniantly puts the engine into the right place to fit a R380 gearbox at a later date ( which im doing now )
another issue is the gearstick is in the wrong place
its all very do-able, just alot of hassle
i fitted it for a reason tho  :lol:

i've got some pics on the other computer, ill post them up later on for you  ;)

can I not put the 90 bellhousing on the disco box?

[Disco-Ron]

YOu'd have to change the input shaft at the very least to do that....

[discodug]

the lt77 box in the disco the gear selector is in a different place than the 90 so the gear stick is futher back.If it is a tdi i belive the gearbox mounts in the same place as 90 one does(change all the mounting brackets over from the 90 box to the disco box) if my memory serves me correct the input shaft is the same on all lt77 gearboxes expect the v8 one and it is only the selectors are different.

[extreme90]

nope, input shafts are different
hence the disco bellhousing being 5 inch longer than a 90  ;)
thats why ive got a disco box in my 90, to push the engine forward 5 inches to allow me to keep the origional downpipe and get rid of the steve parker choker down pipe

will everything be a standard fit out the disco if you move the engine mounts 5" forward then?

[extreme90]

nope,
you will have to mod the seatbox ( cut a section out)
mod the gearbox tunnel
mod floor panels slightly
make a new center access hatch
extend pipes ect ect

to paint a picture time wise
i removed engine
gearbox
floor ect ect
made new engine mounts
fitted new gearbox
modded seatbox anf floor ect ect
mated the engine up
tacked mounts into place , removed engine, welded properly
refitted engine
plumbed it all in, make new air system and zaust
all in 22 hours
on my own  ;)
it easily do able in a weekend, like i did  ;)
