300tdi defender with LT77


Recommended Posts

Hi, My dad has just bought a K reg 1993 300Tdi 90, with a LT77. The story goes that it is a genuine LR that was used as a promo vehicle. Its just got me thinking as to what gearbox it has got because the engine is in the correct position for a 300tdi with a R380. I thought it would be a disco box but the Hi-LO lever is in the correct place for a defender.

Could it be a defender box with a disco shaft? what would the bell housing be? a disco one but its not the same pattern so maybe a longer defender LT77 one?.

what rear main set up would it have, the same as the 200Tdi?

Or could it be a 300tdi engine with a 200disco back plate and disco LT77 Bell housing with shaft?The latter seems to make more sense to me :ph34r:

I didnt even know that LR made a 300Tdi on a LT77 untill my dad bought his, is this a rare thing?

Dan :D

isn't that two years before the 300tdi was released - not sure on me dates on this one but how can it be a 300tdi ????

Are there v belts on the front or the other type flat looking belts.

ill try and take pics later. we are 100% certain that it is a 300Tdi after sevral years of owning and messing with 2s and 3s.

The air intake is all correct for a 300Tdi, to lift the bonnet and look at it everything looks as it should untill you try to reverse the thing :blink: then alarm bells start ringing :lol:

The Engine number on my dads is 16L<not shown above 00028(letter)

any chance this would mean it was the 28th 300tdi?

Why on earth would any sane person want to do that?

The engine is further back giving better weight distribution and room in the engine bay.

If you use a military LT77, first gear is 10% lower.

IMO, the LT77 bad rep is unfounded. I had one with 300000 km behind a V8 and it shifted as well as the day it came off the factory floor.

Just got off the phone to dunsfold(very nice people). It was a test vehicle for the 300Tdi and for Disc brakes!(on rear of defenders) and the engine number does point to it being the 28th :)

and the gearbox points to a defender LT77 with a disco shaft and bellhousing :lol:

its also got ARB brackets on the front and rear axle and NO Axle numbers :blink:

not sure of splines yet as its got alloy wheels but i will find out later this week :D

The pipe on the back of the intake manifold goes to the top of the inj pump and there is no pipe to work the acuator on the turbo :unsure: seriously confused :ph34r:

That pipe on the manifold goes to the inj pump to sort out the fuelling as boost increases. On a production 300tdi, that plug is just a blank and the pipe is "T"ed into the pipe that connects to the waste gate actutaor on the turbo. You may not actually see the wastegate pipe as its "under and behind" the compressor housing - there is a spigot attached to the compressor housing to fed air into the wastegate actuator pipe. With "your" set up, boost for the injector pump is actaully measured after the intercooler, where as standard its measured at the compressor of the turbo before the intercooler. Either is ok, nothing to worry about.

Kind of O/T, but why would the fact it's on a Coventry registration indicate it could be a Landie test vehicle, surely they'd come wearing Elihu's plates, like the new ones always have "Bx00xxx"

Because Land Rove may not have registered it .

It may have gone to a dealer in Coventry although Land Rover ran it for a long time

ot sure if landrover registerd it but before i spoke to dunsfold that was the only other thing to back up the story of it being a gen vehicle. i now know for sure that the story and vehicle was genuine and apparantly if you write to a address in the back of LRO you can pay £25 and get a "build sheet" for a vehicle. is this correct?

Yes I did it once for a light weight I had.
