I'm the happy owner of a 2011 958 Cayenne Turbo. Kids didn't fit in my Boxster and I considered a Panamera Turbo but since I needed space for three children in the back the Panamera wasn't going to work for me.

I've gotten the modification itch and noticed there really isn't a lot out there for Cayenne Turbos. But there's plenty for the Panamera Turbo. Since the 4.8 twin turbo is the same as the 970 Panamera Turbo are most of the parts interchangeable? Are there any parts that specifically are not interchangeable?

I'll also post this in the Cayenne threads too.

 

ipd plenum , turbochargers and ix80 manifold will fit but none of the exhaust part will

 

so basically chips and intake parts should fit, but exhaust will not, correct?

 

No ECU and intake air filters are different. GIAC does offer ECU calibration for your CTT and IPD offers a plenum.

 

why would identical engines with identical ratings have different ECU calibrations?

 

Different transmission

 

Cayenne has 8-speed Aisin Warner and 2200+ kg...
Panamera has 7-speed PDK(ZF/Getrag) and 1920-1970kg=)
