Default Turbo Part Sourcing

I'm currently trying to build a D24T to put into my 240.
To my understanding the turbo on the D24 is a Garret T3?

Picked up a turbo with a seized block. Turbo is covered in oil and rust.
Any recommendations on how to remove these screws/studs? They seem more problematic than usual...

I've removed most, but several seem to be seized in place, especially the four on the back (which I think is a waste gate valve cover?) I've tried a MAP torch and penetrating oil with no luck. Due to the rust/corrosion, the screw heads all seem to be slightly different sizes.

What parts should I anticipate replacing?
I would like to replace the gaskets at minimum.

What keywords should I use to look for parts and what suppliers/venders are recommended?

I've found some parts on MercedesSource, but not sure if they are compatible: https://mercedessource.com/store/sea...s=Garrett%20T3

Why do you want to open it up? Excessive play?

The engine was in rough shape, so I would just like to do a thorough examination on everything before installing into the build.

Play seems fine, but this is the my first turbo, so I don't have a "base line"

Just want to remove the turbine, clean it up and the housing, replace the studs/screws on the housing, paint it and replace any wear components such as gaskets/seals that are easily accessible.

It is a Garrett T3 as you said. It's a somewhat unusual version due to the poppet type wastegate. You can swap to various other T3 versions, but stick to sources from diesel engines, as something designed for a gasser will not have the correct geometry to spool and perform right on a diesel.

I heard someone say that one from a Mercedes 300D (OM617 type) engine is very similar, maybe close enough to bolt right on. Can't speak to any differences in performance. The OM617 is a larger engine so if the turbo is correspondingly larger, it might be less restrictive and improve top end flow but sacrifice lag and driveability.

Never hurts to have a turbo checked out before bolting on, I agree with that plan. If the center section (bearing/shaft/wheels) are in good shape, cleaning up and reassembling should be fine. D24T turbos are long lasting and rarely fail.
