Best turbo supplier?
I’m going to have the twin turbos replaced as preventative maintenance. I’ve looked at the web and there are several suppliers of recon units, all about the same price. Does anyone have any suggestions as to the best suppliers? I’m not looking to buy cheap, I want the best quality I can get.
Any advice or direction is appreciated!!

Looks promising but they are not exchange units - they recon the existing ones. My workshop won’t tie up a ramp waiting on a return on components.

I bought new, they didn't want mine in exchange although it was expected they would.

As above, brand new OE units.
There were supply issues not so long ago, no idea if they have been resolved, but I've checked with out supplier. Both sides are in stock My D3 Build Thread

Bought a pair from Garrett - original turbos remanufactured by Garrett themselves.

Just out of interest and slightly off-topic but what's the thinking behind replacing the two turbos as preventative maintenance? Are they common failure points with catastrophic consequence? And what, if any, are signs of imminent failure?
I'd also be interested to know what kind of cost is involved in buying replacement units and getting them fitted. Mine (singular, as D3) has lasted 250k but it's on my mind as probably being on borrowed time.
Thanks
Chris.

The most common issue is a sticking actuator on the secondary turbo- it’s either the actuator linkage seized (due to rust etc) or the actuator ring (inside turbo) stuck due to excessive carbon build up. Turbo bearings also fail if oil is too thin, or possibly oil starvation or oil contamination. If the seals in the turbo go completely, then the engine can over rev on its own oil, causing catastrophic engine failure.
Turbo failure symptoms are lack of power, excessive smoke from the exhaust and/or excessive oil consumption.
My truck has already done 160k and I need it to do another 160k so I am having a whole heap of preventative maintenance done on it requiring the body off. Rather than wait for a turbo to fail, I’m erring on the side of caution.
Two remanufactured turbos from Garrett are £2k plus VAT

Thanks NC500 for the reply. All good to know. Are you having any major work done to the engine itself as part of your preventative maintenance or sticking to frequent oil changes?
Thanks.

Nothing to the engine exactly but I am replacing:
Inlet manifolds
Oil separator crankcase breather
Both egr valves
Coolant crossover pipe
Fuel leak off pipe
Oil pump
Belts
Alternator
Turbo shut off valve
Intercooler hoses
These are all the weak areas that are prone to failure so at 10 years and 160k miles I thought it best to get ahead of any issues.
I’m also replacing:
Front and rear suspension arms
Air reservoir tank
Fuel tank guard
All four suspension struts
Both valve blocks
All height sensors
ARB bushes
All drop links
Earth strap
Fuel filter assembly
Engine oil and filter
Gearbox oil and filter
Coolant flush
Power steering flush
Inspect and replace brake lines and hoses

Decent list,
Is it also worth replacing the oil level sender in the sump as these are also known to fail?

Check egr metal pipes aswell as they corrode where the clip is fitted around the cover. Bolt snapped when changing ours resulting in body off.
