The easiest way to tell is that the s5 doesn't have a place for the EGR valve on the intermediate housing. Also, the s5 has a hole for the knock sensor above the trailing plug as detailed here: http://www.banzai-racing.com/faq_housings_ID.htm

S4 J-specs also don't have EGR.
S5 TIIs don't have the twin scroll actuator.
The wastegate arm is bent.
The turbo flange looks like a standard T4 flange instead of the proprietary S4 flange.
The intake manifold runners are bigger then S4.
Electrical metering oil pump.
Pulsation damper integrated into fuel rail. Fuel rails are steel tubes instead of aluminum castings.
Dual TPS.
Off the top of my head that's all I can think of...

There's only one knock sensor. On S4's it's on the centre plate under the oil filler, and on S5's it's above the trailing plug on the front rotor housing. This is the easiest way to identify a nude block (i.e. no accessories).
