Ok....thanks a lot, I thought that the Unit Injector System was the loudest, I know that Common Rail is the quitest motor but from your answeres it depends more on the quality of the sound-proofing how loud it is inside the car. I have heard of mats that are permeable to air but also insulate the sound, I think I will try them. But first I have to get rid of the rust in footwell. :(

bastard heavy though, i have a it of ex-NCB belt dated 1988 about 2.5m long and its outrageously heavy! Great as a huge mat on the floor!

Good sound insulator, but you're right it's heavy. For me, the issue is the number of suit cases that pile up! :rolleyes: :p
 
Remember the Tdci models had higher ratio transfer boxes from the factory than previous versions which accounts for a great deal of the extra refinement, along with better soundproofing.

You can achieve the same thing on earlier models by fitting a different transfer box or fitting an overdrive. My 200Tdi 90 was base spec when I got it but I’ve added extensive soundproofing and an overdrive and can now cruise comfortably at 70+ without excessive noise. Can’t say the same for the fuel consumption though! :D
 
I thought Tdci had the same transfer box. They do have a 6 speed.

And yes you can quieten down a Tdi. But they will always be unrefined and noisy. You notice this when you get in a non Tdi Land Rover.

Even a Tdi Discovery is no where near as refined and quiet as a V8 one. And a standard Disco has way better sound proofing and NVH than even the most heavily home spun Defender setup.
 
It’s a 1.2 box in the Tdci. Hence the 6-speed gearbox, the extra low first makes up for the higher ratio transfer box.

Absolutely a Tdi-powered Land Rover will always be less refined than a V8, or even an earlier indirect injection diesel one. An early Discovery is just a Defender with a better-built body on top and will easily do 90% of what the Defender will do just in more comfort. Its a shame the bodywork rusts so badly.

The reason I have done the work to my 90 is because I do 30k a year in it. A Discovery would be quieter, more comfortable, cheaper, capable of everything I need, and less likely to get stolen. But I want to drive a Defender, and so I do - 500-600 miles in a day without major issue.

OK well l own a 2005 TD5 110 and on the motorway it’s fine, no need for earplugs

l’ve not done that much to it. Firstly it’s the Station Wagon which means carpeting throughout.
I fitted soundproofing to the bonnet and a few pieces stuck to some bare metal under the second row seats, and under the front cubby box/front seats.
Apart from that it’s standard County Station Wagon.
Best cruising speed is 65mph, after all it’s a Defender 110.
It’s worth spending time sorting out any rattles, bad door seals, unused holes in the bulkhead (put a rubber grommet in any you find), door rattles (for instance the window glass channel tends to rattle against the inside of the door skin, a cable tie round one end of the channel cures it completely) check the seals on the vent flaps etc

l have found that the XS version is a bit noisier at speed, the noise seems to come in through the aircon gubbins in the passenger footwell.

This! Mine is fairly loud but far from unbearable and I do drown out with music to be fair. I had all sorts of whistles and noises. I replaced vent seals and door seals with genuine, replaced rear window slider seals, I put silent coat sound deadening over inside face of bulkhead when I had dash out and also did gearbox tunnel. I then put some closed cell foam ontop of silent coat on footwells.

I think if I went whole hog and overcoated the pads on bulkhead then did rear of the truck, I'd get quite a good result.

If your at motorway speeds all the time change transfer box to a longer disco one. I'll be doing that when it goes in for a clutch.

They are all noisy until a good two inches of cow chit and straw has built up in the footwells.

Lies. It never has chance to build up, the door seals/gaps allow water to rush in every time it is damp and flush all of the farm build up out the rust holes in the foot-well!

My TD5 110's the same, new seals, silent coat and carpet on top, nothing under the bonnet though and the roof just thin headlining, might get around to doing that as I think it could still be better
Up to 50 or so it's fine you can hear the radio etc then you need to start semi shouting

I’ll likely swap my disco and fender transfer boxes overs both are leaking lol.
I still have a little water leak after putting sika in all joints and new seals everywhere!!
I want carpet but can’t when I know it still leaks
