Easiest way to tell S4 from S5 engine
What is it physically on the outside of the engine. I did a seach but can't search for S4 or S5 cause it's under 3 letters. Motor is out on the ground. Doin't know what year it is. Whats the easiest way to tell. It's a Turbo out of a 2nd gen.

series 5 ... works for me in a search
i would look at the oil metering pump ...
if it has a long *** arm going to the throttle body, i would assume its a series 4
if not ... series 5

well you can seach for s4*and s5*
the front cover is a good way but you can't be 100 percent sure. I've switched covers before on engines.
The only true way is looking at flywheel/rotors.
98 percent of the time you can do it by visual but then you get frankenstiens out there too.

The S4 knock sensor is located on the center plate under the oil filler pipe. The S5 knock sensor is located on the front rotor housing above the trailing spark plug.

I have an S5 ECU and harness, and it runs fine. i think the oil pump and that sensor are good ways to tell, other than ripping the whole thing apart and analyzing the pieces...

The water fill neck is plastic on the S5's, but like someone mentioned the front cover/waterpump housing can be swapped on "franken-motors".
