How interchangeable are turbos

looking at this '96 xantia td engine I've got and I've started searching for spares.
I've got a garrett t2 454131-2 turbo and whilst the peugeot and xd cars share the same engine and ancillaries the turbo id number is different.
Can the xd turbo 454027-1 turbo, for example, be used on my engine or is it a big no-no.
Can't see why there are loads of different turbo's for the 1.9d in the xantia,(and for the 1.9d in general) when they are all designated as a t2, is it a number exercise by garrett or did they change the turbo output that frequently???

As the power output for all applications is the same (I think) I would have thought any of the turbo's would have suited. They used two different turbo's on my CX td but everything else was the same.

I thought that too.
I think there are 2 different garrett turbo's, a 0.6 bar one for the DHW engine and 1 bar for all the rest, but there are about 16 garretts listed for the 1.9td engine in bx/xd/xantia form???

I can only assume that any differences are in shape, mounting position and maybe exhaust flange/coupling for different applications. Everything else must be the same because all the XUD engines are the same (exept the 2.1)

There are at least two KKK turbos too. I know these are interchangeable because I carried out the swap myself. There was no change in boost or anything else untoward, so I assumed them to be basically the same. All fittings were identical too.

The only thing I noticed was that one seemed to be considerably better manufactured than the other. One being covered in rough edges and just generally not looking very well cast. Even the serial number was all uneven. The other one was completely the opposite. Everything neatly finished and a pleasure to handle.

Presumably they were just from different manufacturing plants and that's where the difference ended.

There are two different power outputs, dont forget that the SD has a turbo. The turbos aren't all completely interchangable, some of the vans and the people carriers have different manifold and turbo arrangements. That aside the rest of them are pretty much the same thing.

Even if they weren't identical, provided that you could hook up the manifolds and the oil feed, a turbo is a turbo pretty much. If you put too small a turbo on an engine it will run too fast at high revs but you'll have plenty of low down torque. The other way around gives no boost low down, then rocket like performance further up the rev range!

I had forgotten about vans. My CX had a Mitsubishi turbo!

I changed a turbo on a 405 TD, with what i thougt was exactly the same thing. After putting it all back together i realised i couldnt change gear

the manifold was 1 cm shifted left on the new turbo, and fouled the gear linkage.. I think that Turbo may have been from an auto...

anyway, lesson learnt

This takes me back to my xantia days, the turbo blew, and I got a replacement from someone on the andyspares forum.

It arrived, and the air pipework on the intake side would not fit on the turbo - they were different connections.

The chap had the pipework spare ( he was scrapping the car ), so sent it to me - job sorted.

Beware, some are "innies" and some are "outies"

Just in time. I'm changing my KKK turbo to a garrett from Fiat Ulyses but the exhaust flange is too large. Heard that garrett is better than KKK. Furthermore, there's no service kit locally for KKK but there's one for garrett, so that's another reason to change it. Hopefully can find a flange that fits.

One of my Xantias is KKK the other is Garrett.

I can't really tell the difference. Initially I thought they were different in terms of low down torque and how the delivered boost but after removing a CAT and putting new air filters in there isn't a lot to choose.

The newer one is quieter (not sure which make) but its done less miles.

Garrett and KKK are interchangeable provided that you use the right steel oil line, another difference seems to be that on BX the pressurised outlet is held on by a hose clip, Xantia/306 seem to have a 2 bolt flange here.
