All Evo 4-8 Turbos are twin scroll designs meaning that the engines exhaust is divided into two channels (see first pic). As the engine exhausts in pulses.. its supposed to result in quicker spooling. From the Evo 4 onwards, the Turbo spins in the opposite direction, i.e. Anticlockwise (hence the R in the turbo name).
The Titanium Alumnide alloy used in the RS/RS2 and some GSRs (factory option) has less inertia and thus spins up around 500 rpm sooner.
These Titanium turbos can be identified by the “A” in their name.
Addendum:-
