Stock Turbo Specs?

[morbid1]

I recently got a 90' Targa Turbo with 49000 original miles on it so of course the first thing Im doing is research and for some reason I cant find the specs on the stock turbo. I've looked at a number of replacement or "upgrade" turbos and I dont know if I need a 3 bolt or 4 bolt (t3 or t4?) and what the actual size of our turbos are (inlet, outlet) anyone have any links?

bolt on turbos will pretty much be ct26's with upgraded trim.

xt26 uses a 4 bolt square "CT" flange T3 is a rectangle flange and T4 is a bigger version of the T3 flange. the dump flange on the CT26 is a 4 bolt and it has a 3" inducer. apart from that its water cooled.

maybe some else can fill in the turbine specs?
