0-60 the Boxster is faster. Plus my Boxster has some mods done. The last dyno I did I was putting down 240HP at the wheels with it. Plus it has been lightened with the exhaust mod and the GT3 seats. Shifting from 1st to 2nd is much quicker in the Boxster. The Carrera doesn't come alive as quick, but once it does, it moves. The mod bug has bitten me hard. Now I don't know which car to work on. I will probably do an exhaust and intake on the Carrera soon. It's not loud enough for me.
The Carrera also needs some suspension work. I'm use to the Boxster now and need that in the new car.
