Can anyone help me ID this AiResearch turbo?
 

Looks like a T3. Marks on the cold side look like 84, probably A/R. Also has "M11" cast into it. No ID plate. No marks to speak of on the hot side other than a "12" cast in. I bought it a few years ago because reasons. I just remembered I had it and thought it might be good for my Miata project. Nudes of it:

Any idea on specs or maybe even a compressor map?

Anyone?

This may be the turbo from a LeBaron GTC Turbo.

Its basically a Garrett T3. Take some measurements to confirm.

Compressor housing A/R .42
Exhaust housing A/R .48
Compressor inducer 42 mm
Compressor exducer 60 mm
Exhaust turbine diameter 48 mm

Thanks, I'll get some measurements.

yes just measure it.
