Telling SR20DETs apart visually:
S15 vs S14 Engines:
S15's have higher CC injectors, they are red.
S15's have a cast divider in the turbo elbow
S14 Kouki vs S14 Zenki
Kouki S14's have fins on the head. -thank you sblack13
S14 vs S13 Engines:
Look for the bulge on the front of the engine and the slant at the back of the valve cover.
Look at the intake manifolds, the S14's intake manifold has the throttle body higher - thank you sblack13
S13 Redtop vs S13 Blacktop
Color of the valve cover (obviously)
All blacktops have fins on the head
Blacktops have a fat O2 sensor
S13 Blacktop vs S13 Type-X Blacktop
Look for the J4 ECU on the Type-X, I don't know of any visual way between the engines though.
