Feedback on swapping 4.2L engine from 2009 S5 into 2007 S4 4.2L Cabriolet

[Baxterici]

Seeking feedback on whether the 4.2 L engine from 2009 S5 Coupe VIN WAURV68T49A029273 can be installed into 2007 S4 Cabriolet with VIN WUARL48H97K900932. Need to know if motor mounts can be purchased to allow S5 engine to be mounted in S4 Cabriolet? And what electronic solutions there are? Doable or impossible?

The S5 motor is a FSI motor and the B7 S4 is not. They're not easily interchangeable. The fueling and associated electronics are different, this isn't a weekend job. It CAN be done, but you're definitely better off finding an engine that the B6/B7 vehicle came with.
