And the conclusion is ?
Well my uprated turbo arrived yesterday so I fitted it.
Whilst there were no problems fitting it I could have shortened the job I think.
If I were doing it again I wouldn't remove the turbo.
Take off the heat shield, the oil feed and return pipes, the pressure hose to the turbo waste gate actuator and the air hoses.
Remove the circlip holding the actuator rod to the waste gate and undo and remove the four bolts (8mm) and semi circular retaining plates from the exhaust side of the central body. A couple of taps gently with a hammer and the centerpiece comes out. Clean the mating surface on the exhaust body, it should just need a wipe around as the original turbo centre was clamped to it.
Undo the six bolts holding the snail to the centre section and tap apart.
The new intake wheel looks the same as the original one but has about 5mm longer vanes.
Clean any muck (oil and dust stuck to the inside) from the intake snail.
Fit the new centre section and loosely fit the four bolts and plates, align the ports for the oil feed pipe and return pipe, bolt up the return pipe using the new gasket and tighten the four holding bolts. Before fitting the oil feed pipe gently squirt some oil (supplied in a syringe) into the oil feed port, spin the compressor fan as you do this to ensure the bearings have lube before start up, then fit the oil feed pipe with new copper washers supplied.
Now fit the intake side of the turbo body, ensuring the 'O' ring stays in place. Loosely fit all six bolts and ensure the waste gate actuator mounting tabs are at the top and lines up correctly with the pressure port facing down and out from the motor, refit the actuator rod to the waste gate and refit the circlip.
Now tighten the six bolts going cris cross across from one side to the other, finally check by going around them.
Refit the heat shield, do not be tempted to leave it off you will melt your washer hoses and (I did) set fire to the sound proofing on the bonnet.
Refit all hoses and you should be ready to go.
I believe doing it this way negates having to get new manifold to turbo and turbo to exhaust pipe gaskets, (not supplied) and time to align everything as you do it bit by bit.
NOTE, warranty is only available if you have a problem if you have fitted new feed and return hoses/pipe, new air and oil filter along with new oil and you can PROVE IT WITH THE PAPER WORK.
Hope this may be of some help.

And the conclusion is ?
There is a steep section of road that used to knock my speed down a fair bit, I never measured it before but now on cruise control at 110 it drops back to 100. That seems a lot better than it was but like I said I hadn't actually measured it before.
The vehicle certainly feels less stressed at 110 and holds that speed everywhere but this steep pinch.
I believe it's main benefit will be what it allows a remap to do but economy may be boosted by having more air in the cylinders.
Feel is better but hard to quantify.
Cheers

Just confirm, did you use this https://www.turborebuild.co.uk/websh...Cartridge.html ? or something similar?
Discovery Td5 (2000), manual, tuned
Yep,
Just confirm, did you use this https://www.turborebuild.co.uk/websh...Cartridge.html
that's the one.

I installed my core today. I followed nismine01's instructions and didn't remove the turbo. On the whole much easier. There were a few bits that would have been easier with it off the car, but not enough to make me want to remove the turbo. I have added some photos and added to nismine01's instructions. (I like to look at other peoples pics, so I posted a few).
All up it took me 2 hours including photos.
The before:
I don't have a heat sheild

Remove the circlip holding the actuator rod to the waste gate
A couple of pics with the provent piping removed and shot of the circlip.
The circlup was easy enough to remove. Just watch it doesnt flick off.

and undo and remove the four bolts (8mm) and semi circular retaining plates from the exhaust side of the central body.
These are a little difficult, you can't get a socket or a ring spanner on them as there is not enough clearance. I needed to use an open ended 10mm. If you notice from the next pic, I couldn't get one of the nuts off. You only really need to remove the top and bottom ones that are closest you. You can then lever the plates around. Once they are up, the core will come out. There is no reason to remove them entirely.

A couple of taps gently with a hammer and the centerpiece comes out.
Mine took a few more than a couple of taps to come out. I needed to get a small pry bar to lever it out.

The bolts simply hold the core in place. They do not actually bolt right through it. So it doesn't have a specific orientation for the core. pic of the bolts too.20170902_134602.jpg

Pic of my old one and the intake snail. not overly oily.

The gasket they sent me was wrong, so I had to refit the old one.

Loosely fit all six bolts and ensure the waste gate actuator mounting tabs are at the top and lines up correctly with the pressure port facing down and out from the motor, refit the actuator rod to the waste gate and refit the circlip.
Now tighten the six bolts going cris cross across from one side to the other, finally check by going around them.
Note that the feed and drain pipes are too close to the backside of the core and wont allow you to get them in. So once fitted and before you tighten up the other bolts, spin the snail around to allow you to wind the bolts in so they clear the pipes. Then spin it back to align it properly, and then re-tighten all the bolts.
Refit the heat shield, do not be tempted to leave it off you will melt your washer hoses and (I did) set fire to the sound proofing on the bonnet.
Refit all hoses and you should be ready to go.
the big question being. Did it make any noticeable difference.
Yes and no. I had 245/75/16 wheels on my car previously. I then put on a set of 32" muddies from a car I parted. I ran them briefly and sold them and put the 245s back on. Then yesterday I got a set of new mickey thompson deegan 32s put on.
So I really cant say what difference it has made as I'm not all that used to how it drives with the new tyres.
However, it does make more boost. i will need to wind my wastegate modulator down. I'm hitting 20psi quite easily without having to bury my foot too far.

						Thanks for the write-up folks. Mine arrived today. Will be fitting it on the weekend. I think I'll leave the turbo on the engine too. The cartridge looks pretty simple to remove in-situ on the defender.
Be interesting to see what difference it makes - given the remap I have. Unfortunately the new Allisport intercooler I order a few months ago won't be going on as they are still having supply issues. Not sure where to go for an equivalent. Not sure the TRS ones at $500 over the price of the Allisport are the way to go, but don't seem to be too many other options.
