Primary turbo is Journal Bearing and Gucci as fuck.
WILL blow by 250,000km, has a rather unique combination of flange and housing.
Subaru wants $5k for a NOS turbo to replace it - buy one as soon as you can off a junkyard - got one from Abu Dhabi for $300.
Alternatively, you can grab a turbo with the same housing and core off an Isuzu N Series, and have the flange welded on.
Stock computer doesn't handle a tune, at all.
Just do a single turbo conversion, use an aftermarket ECU and wind in the boost.
Just think of it as an easy way to get an open deck EJ207 that revs to 8 grand and doesn't cost as much as an STI.
