ALTHOUGH I DRIVE A MAZDASPEED PROTEGE I RAN ACROSS A GREAT ARTICLE THAT INCLUDED SEVERAL AFTERMARKET MANUFACTURERS FOR MIATAS: kennebell.net "Stock the Miata puts down 109 to the wheels. Typically if you add a barr (14.7 psi) of boost, you double the horse power. That's the theory. But our 12 psi intercooled kit, the power went from 109 to 235 WHP!!!!"
