A mixture of both! Honestly, for the average joe, stick with the REW. It's the better choice based on convenience alone. If you'd like to experiment or plan on making big big numbers for race duty, get your hands on some good cosmo plates, new preferrably. As for the intake manifold, lots of opinions but I've never seen any hard, factual proof. The larger runners of the Cosmo suggest more flow potential. Is the plenium chamber a hangup on it? Why didn't Mazda use a plenium design with the third gen? Dunno. Someday here soon I'll have the resources to test everything out myself. My hopes are that the larger stock primaries and secondaries, with maxed out secondaries will make a nice street setup and produce really good power at slightly lower boost levels. We shall see.
