Wikipedia seems to think that 4GR has D-4S but you never know.
D-4 is direct injection, right? Or is it still port? (I've seen sources saying both  ). I know D-4S is a combo. |
D4 is direct injection, D4-S is "D4- superior" which is direct + port. And I'm pretty sure only the engines I mentioned use it, hence why it was a pretty big deal when ppl figured out the engine in the GT5 preview said "D4-S".
