Ratio of transfer boxes ????????????

I`ve recently bought a 1995 disco, problem is top speed at 50mph it`s reving at 4000 which is not good, it`s modded for off road and I was told it has a defender transfer box on a recon g-box, would changing the transfer box to a discovery one make much difference? and how easy are they to change??

it would make a noticeable difference, its a heavy lump nut easier with a engine crane through the tunnel

Yes it would but you could also fit bigger wheels, what size tyres have you got fitted at the moment?

Transfer box is do-able by yourself, but as James says it's a bit of a heavy lump and hangs lop-sided onto the main box.

I've changed mine by myself, but it's as much as you want to do to hoist it up onto the gearbox stud.

There is some helpful stuff here: http://forums.lr4x4.com/index.php?showtopic=14601
I recently saw where someone made a wooden cradle to support the transfer box It was very impressive.
There was a picture but I can't remember where it is
Dam those Alluminium saucepans.

My Defender 1.4 TBox works great in the Disco with 315/70/17s (34.5").
