What are the differences bewteen 13BREW and 13BRE?

I was flipping through some old copies of Sport Compact, and one of the RX7s had a 13BT in it, and ran some kind of ridiculously low quarter mile time, and burped out 550 horsepower, using a 13B-RE from a Cosmo. Aside from two rotors and hitachi turbos, what're the main differences between the 13BREW and the 13BRE?

2 door sedan, and its more like the 13B-REW (twin sequential, intake manifold and lots more), just a slightly older version.
But I would love to hear what the differences are between the RE and REW if anyone knows?
