Default Garrett turbo ID

So as you can probably tell from my name, I am looking to put together a DIY turbo for my 90 1.6 and trying to do so on as strict a budget as I can without making too many compromises.
With that all said, I知 working on my MS3/x as step one, but while I知 doing that I知 trying to source other parts. So I came across this turbo for sale locally for what seems to be a good price ($350, negotiable), but I知 not sure its what I need. Been doing a lot of research and still cant quite figure out if this is the GT28R I知 looking for. If anybody can ID off pics, I would apprciate the help.

I'd look for a 2554 or SR20 turbo (nearly the same). They fit FM's DIY turbo manifold/dp kit, and spool great on the 1.6. I haven't tried a 2560 with a 1.6, so I'd be hesitant to even suggest that. IIRC when I had my 1.6 sr20 setup, I was on par with spool plots from 1.8/2560 setups, to give you an idea.

IMO too big of a turbo quickly turns what's supposed to be an amazing car into a dyno queen/waste of money. Not to mention I don't think that turbo is standard t25, so you'd be building a custom manifold and downpipe to fit it, breaking rule #1, never build a setup around a turbo.

I appreciate the pointer in the right direction. So I have a follow up question about something I知 running in to: locally I find several turbos for sale (craigslist, offerup etc) but people selling them don稚 know model numbers or types, only what痴 written on the side. So I have been searching the forums and google trying to find a resource on how to visually ID them with no luck.
Is there a place that I can go to start learning to ID what to look for?

If they can't tell you what the turbo specs are, you don't want the turbo.

True. Junk turbos are easy to find in junkyards but seldom good to use. They end up being thrown away. I chucked a bunch over the years.

If you can't afford a $300 turbo, you can't afford to turbocharge your toothbrush, much less a car.

If it is your only car, you are about $2500 away from getting ready to buy the parts to turbo, which will be another $2500-up minimum. I say this because you will need to pick up a second beater car to drive while yours is being built. Not even kidding.

This is truth, any number of things can go wrong causing your car to be down for days or weeks.

Perhaps, but this is something you can/should plan for.

For me I have a back up vehicle, today went to do a clutch in my car and FM sent me the wrong pilot bearing. so it's going to be sitting without the trans in for 3-5 days until I can track down one that fits and have an evening to put it back together.

That's better. I'm calmer now.

Or maybe it is the bourbon.

Try to find a journal bearing 2554 from a SR20DET on facebook or craigslist. I couldn't find any in my area so I sprung for a legit 2554r, which I felt stupid about at first, but then again I spent on a turbocharger instead of $500 on a 1.8 swap so I might as well just own my stupidity
