From poking around the Ecomodder site, it sounds like Saturns take pretty well to warm air intakes - tricking the ECU into running lean by routing the air intake near the exhaust manifold. Maybe this works well with Saturns because their engines are in backwards (who puts the exhaust facing the front, and anything you would need to get at [alternator, water pump, oil filter, etc.] in the back of the engine bay, anyways?).

Also, again from other EM threads, it also sounds like a taller 5th gear swap is relatively easy to do without pulling the transmission.
