Welcome to the forum!
First off, on the forum alot of people will refer to the Turbo I, II, III, and IV motors as TI, TII, TIII, TIV or T1, T2, T3, T4 motors.
The 87 Shelby GLHS used the intercooled 2.2 TII engine (but it wasn't a true TII, it used a TI block, just to make things more confusing!)
The 87 Dodge Shelby Charger used a non-intercooled 2.2 TI
A non-intercooled 2.2 TI can fairly easily be upgraded to be like a Turbo II in appearance and performance with bolt on parts and minor modifications.
I like this shelby-dodge.com for the finer details about these type of cars,
87 Shelby Charger 85-87 Shelby Charger
