Turbo Identification Hep

[1984 t-type]

I'm trying to figure out what turbo I have. I posted pics before but no luck, so where and how should I take measurements to try and get an idea of what I may have? Pictures would help out a ton. Thanks

I recomend reading 101 102 103. There is a ton of info on here.
