black top is the S14 motor, its newer slightly more HP

Red top is the S13 engine

Everyone has them for a reason, cheap, easy to make power, abundance of parts

S13 Redtop = early sr20det
S13 Blacktop = late model sr20det

s14 Blacktop = sr20det with variable intake cam

S14 motor makes more power from the factory and I think has a bigger turbo. But the S13 motors have better flowing heads and more potential.
