Disco or Defender gearbox ?

[90Mike]

Hi Guys does any one know what the difference is between the R380 gearbox fitted to discovery td5 compaired with the R380 on the defender  :-. ,i am looking at putting a td5 engine and box in mine from a discovery but the gear stick and transfer box leaver is the other way around and i wanted to try and keep it looking as origanal as possible cheers Mike

not sure about the 380 but in the lt77 disco box the levers are further back as well in order to swap them over you have to replace the whole lever/selector sections.

So could i just use my discovery R380 box and just use a defender TD5 transmission tunel,does any one know if this would be the correct way to start lining everything up :?

apart from the obvious with the gear sticks being the wrong way ( disco = short stick ) vs (defender = longstick)
the input shaft and bellhousing and input shaft is kin huge  :shock:
you will need the defender r380
if you run the t/box on the existing mounts and run the current props you can keep the trans tunnel and floor in
ive done a few td5 conversions now on defenders and its relitivly easy if after the first one
you will need defender looms and ecu as the disco loom and ecu wont be any use
what you doing about the tank ??
expect a s*** load of leccy gremlins all due to poor grounds

hey there mike 90  like extreme90 says use defender gearbox and u can use 90 tank with a bit of modifying as for loom if your good a wiring u can use disco loom and ecu and get rid of half the wiring

[90Mike]

I can get the discovery box converted for £200 inc the sticks but i thought that the denfender box had a long bell housing as well because the engine sits so far forward,as for the tank i was planning on using the standard tank as it is already fitted with a fuel pump for the v8  [-o< cheers guys

[extreme90]

yes but what pressure is the output ?
a td5 has 2 cycles
low pressure out to the fuel filter
fuel filter then back to the tank/fuel pump where its dumped into a swirl pot
then to high pressure and out the the engine

you need a swirl pot to stop fuel starvation on anyform of hills with it

p.s its alot easier to use defender looms as it looks neater.
disco looms are good for running td5's up on the floor  :lol:

[90Mike]

The plan is to use a defender wiring loom so at least i can get ECU in to the cab but still use my discovery ECU so i guess i will be looking closely at the pin numbers just  got to wait for postman to drop it off


Now the confusing bit just got the g/box & t/box out of the disco measured the bell housing against a mates defender td5 and they are both the same  :? :-. 
 

[extreme90]

yes they are, the gearstick is just back to front
if you use the disco ecu the guages will work back to front
