MT detectives, help me ID my old POS turbo
2 Attachment(s)
Was puttering around in the garage, found my old quick-spooling turbo. It's some species of T3/T04B I think, but I'm not sure exactly what size because none of the measurements I've taken match any known compressor wheel sizes. I figure I'm either measuring wrong or I'm retarded or something.
Anyway, here goes: Compressor: 8 blades at inducer, x2 at exducer inducer diameter: 47.59mm exducer diameter: 67.93mm Turbine: 11 blades about 2.1" at exducer says GARRETT on the back of the turbine with M-4 PT-2 AR.48 on the inlet of the housing Don't really care much about the turbine housing, mainly curious what compressor this is. Here is a picture of me measuring the exducer diameter of the compressor. https://www.miataturbo.net/attachmen...ine=1442782911 |
Compressor housing is 2.75" inlet, 2" outlet btw.

There are a number of compressor wheels with specs in that range. See this chart.
Turbo Compressor Chart Edit: Also, post some pics of the whole turbo. |
Yeah, I'm aware there are many turbos that are close to that size. That's my problem. My measurements don't actually match anything and it's so close to so many plausible turbos I have no idea what I'm looking at.
There aren't any markings on the turbo besides A letter C on the compressor outlet and the text I described above. The center section is an unremarkable oil cooled, journal bearing center section. The turbine housing is a typical 5 bolt internal wastegated housing with a T3 flange. |
