The 1.9 gets to a point where it is very inefficient, upgrading to the 2.3 ZR1 blower leaves all your factory lines and connections in tact and provides you with a better way to create boost on your car and not have to spin the blower so hard. The 2.3 creates so much more air then the 1.9 that it can produce more power with less boost
