I recently picked up a 1988 MKIII parts car. While checking the engine out I noticed the turbo had a really small inducer size on the compressor wheel. I know there have been many variations of the CT26 but which one is this? Any ideas?

It says CT26 on the compressor housing but does not say Toyota like most MKIII's. Also the band clamp holding the CRHA to the turbine housing is different than the ones I've seen. The coolant hard line has a difference as well.
