Default How to tell the difference between S4 & S5 T2 motors.

Howdy folks,
A friend and I are looking to finish a n/a swapped to T2. We have the trans and everything else behind it. Keep in mind this is a S5. We want to keep it as a S5 T2. This brings about the question:
How could I tell the difference from a T2 s5 motor and from a T2 s4 motor ?
Thank you.

Easy.

OMP is different (electric S5, mechanical S4)
Turbo and manifolds are different (S4 looks like it has two wastegates, one is the twin scroll actuator)
Injectors are different (S4-square plug, S5 oval plug)
