Hi all,
Has anyone had any luck "transplanting" a turbo's core ie the vanes and bearings to a unit with a bad core?

This one almost fits, but is a TD0411g5 instead of a TD0411g4 so the outlet is in a different place.#

Thanks!

Well, in theory it should probably work, the same core will be shared between a number of different housings to save money. The turbine and compressor wheels may be different sizes, but you would hope that would be indicated by a different part number.

In practice it's a lot easier to just sell the car and buy a faster one tongue To work well with a turbo, an engine needs stronger construction, better piston cooling and a lower compression ratio than the N/A version.

What Steve says is correct, BUT turbo's spin at very high speeds in very dirty environments, so the tolerances of bearings, etc are critical, also, you 'may' find thrust washers etc. for end float control (I don't know). It should work, but I'd check everything as you strip and re-build. If you already have both you don't really have anything to lose by trying it.

I guess it should work, but I would worry about the balancing.

Parts needs to be in same angle compared to each-other in order to have any hope of preserving it (given you don't have a balancing rig)
