Hey
The hotair turbo will mount on an intercooled application with no problems. It will not have the power the 86/7 turbo's will, but it will work on the system quite well. I've known a few guys who have done this, and even ran some good numbers at the track . Theres a serial # on the lower section of the compressor. That will identify what year turbo it is. You can also do a physical comparission with the external and internal characteristics on the gnttype.org turbo section to see if you can identify your turbo.
