I was reading an article that said this:
I was wondering if it was possible to add a second turbo?
The Speed6s 2.3L turbo DOHC in-line four pumps out 274 hp @ 5500rpm. Thats a lot of horses for a mid-sized four-door. But roll on the gas and nothing. Goose the revs above 3500 rpm and 280 foot pounds of torque comes on like a fire hose. If Mazda added a second, smaller turbo or figured out how to make this sucker spool-up faster (call Porsche), the Speed6 could shave a half second or more from its 5.4 second sprint to sixty. That's WRX country, and not a bad place to live.
