disco t box

[biggerlandy]

hi i know spoke about doing it but has anyone put disco t box in there defender and what do they think :)

[Guardian.]

not done it but there will be hardly any difference, bar drop the revs a tad in main box, cannot see it is worth the agro though. :-k

Ive done it and it is worth the effort. I am running a 300tdi on an lt77 and with the defender tbox was revving out at around 65ish but with the disco (300) i can happily sit at 75 - 80 and hear the radio. You will have to drill and tap a couple of holes for the handbrake arm but pretty straight forward. I am running 33 inch muds aswell so the fuel economy is better with the disco tbox. If you have larger tyres then you will need to fit a 110 blue type speedo drive to get an accurate ish reading on the speedo. Any probs mate just holler.

Am i right in assuming the t/b will unbolt from the gearbox in situ.

yep
on a disco though you need to remove the pto cover to gain the 5mm clearnece thats needed to get the [!Expletive Deleted!] off 

[suggs]

would be worth considering whiping the gearbox out too and changing the clutch and fork whilst its all striped out, unless you know when it was last changed..

put new clucth etc in about a year ago so guess i am putting tbox in soon cheers guys :)

Well worth it.

I run this conversion on my otherwise standard 300TDi 90 with R380 & 265/75x16 BFG AT's and it really makes an improvement.
This conversion has been discussed many times on this & other forums but after more than 3-years I still haven't found a situation where I wish I had left it standard. Commuting, towing, M/ways, headwinds, long hills etc, in my opinion it is far better than the standard set-up.

I've been looking at doing this swap on my 300tdi 130 but was a bit dubious as it's quite heavy and didn't want to gear it up too much.  Sounds like it might be worth a try though  :dance:

[Litch]

A loaded 130 may be too much for a standard TDi to cope with on the higher gearing and you may be playing with the gerabox more than is comfortable.
Like I said, works fine on my 90 and I know several 110 owners also like it but a 130 that may spend a lot of its life loaded up........., I don't know.

Well I've got 235/85s on Blue and I find the gearing too tall when it's loaded up or towing and pretty lame on LPG, plus setting off in 1st needs a lot more clutch than is good, though I know the TDi box has a lower 1st.

Sounds fair enough,  have a feeling gearbox is on it's way out anyhow - maybe best not put too much more strain on than necessary  [-X
