Pontiac68buurd,
Don't know if anyone knows on this board (not a cut to anyone if they do), but you might want to try this board:
http://turbomustangs.com/
This is a good board to surf and a good resource. If you don't have any luck there try performance years message board:

There is a guy named Tom Vaught on both of these boards...he would probably know the specs on your turbo. Tom goes by "Boost Engineer" on the turbomustangs board and uses his name of PY's board. Good luck with your project and welcome to the board.
Sorry Gach for plugging other boards.
