Hi mate, good news about the job, if it's a UK car it will more than likely have a tf03 turbo on, imports have a larger td04 on
Pic for comparison
It's a mitsibushi unit so there should be plenty of them around, I believe volvo used them for a while on certian models,
They are oil and water fed so would be easier to find one that has the same kind of set up saves blanking bits off,
In theory pretty much anything will bolt up with some modifications to the hot or cold sides.
A td04 or 05 would give you loads more oomph but to get the best out of it it would need mapping in
