I hear that the non vvt model SR20's head flows a little better, probably why some D1 S15s have S13 motors (or heads at least) on them.
yeah,that makes perfect sense. the following model engine with a bigger turbo and more power would have a less efficient cylinder head.
the D1 guys using S13 engines in later model cars probably have them on hand,and are using a setup they have experience with,and are happy with the output of more so than because it's better std. those engines are about as similar as something in a V8 supertaxi and a production SS.

p.s. the later model engine will perform considerably better,providing you get everything,ecu,loom and the engine. not worth the extra cash unless your current motor is stuffed though.
