Identify this turbo please?

Hi guys i went this evening to look at a T28 for sale, im not sure however, its not like the other T28's im familiar with, so heres a pic:

It is AR80, and it is only oil cooled, there is no water cooling channels atall, also i wanted to ask, there is very little play on the shaft left and right, however inwards and outwards there is some play and if you push the exhaust turbine inwards and try and turn the shaft there is a bit of resistance but if you push in the intake turbine and turn it then its nice and free, so im a bit sceptical anyways but what are you guys thoughts?

Thanks

I am not sure, but it could be the T25's that come off the Z31 300zx's in the late 80's ot just a hybrid, I can tell you this, the turbo is stuffed if you have so much movement inwards and outwards that there is resistance, it will cost you the turbo plus a rebuild which is around R2800 upwards.
