They are T25 turbos. T25 stardard inlet and conical 3 bolt outlet flange (can be found on the oem downpipe or saab tuning shop for custom).
Most Saab people upgrade from that turbo. That is the smaller one and it is almost a direct upgrade to the MHI unit.
The bigger oem turbo (exact same turbine inlet and outlet type) is the TD04-15T with 5 or 6cm2 turbine housing. Pretty tough and reliable turbo and can make just over 300hp(crank) with closer to 350tq on the saab 2.3. found on T7 9-3 Viggen or HOT or 9-5 Aero or later Arc. Most people upgrade to the 19t compressor and gain around 50 more hp. I would be going with the 6cm housing for sure(swappable from older 9000 aero or on ebay) or ebay has a 7cm one as well. for reference most t25s have 7-8cm ones when you convert number.
That is just some info if you wanna go custom with that. could always run a t25 manifold and custom downpipe/lines. A premade kit would still be easier

The Saab ones are a td04hl vs a td04h. Bigger shaft and a better turbine wheel on the hl. Also the turbine housing is completely different as well as the compressor wheel and housing. Oil/coolant ports might be the same but might not. They are closer to the Volvo td04 turbos which are also hl's but a little different and t3.
I used to have a Saab viggen so I know a few thing about then. They are pretty responsive and can beat the **** outta them(in relative for a stock turbo). I've grabbed low km ones locally for 75$ and in great shape too
Only Issue is the smaller turbine housing is the more common and egt's skyrocket.

There is even a variant of the volvo one that shares the same downpipe flange. I ended up getting my downpipe flange from a saab shop.
The built in bypass valve is really cool, makes me feel like i have an EFR![Thefinger](https://www.miataturbo.net/images/smilies/thefinger.gif)
The wastegate design is also really awesome, and I can run 0psi through it with the wastegate disconnected.
