Panamera motor in a 928?

Well, he removed it because whenever he drove near airports, the motor would combust so much air that it would deprive the surrounding area (and thus, the jet aircraft in the airport) of air and effectively create a negative air pressure. Therefore the jets in the airport could not start their turbine engines due to air deprivation!

The 928 hood is too close to the ground to fit the Cayenne/Panamera V8.
federal safety standards have been revised since the 928 to bring the nose up, meaning more room for tall engine packages. If you get a chance, park your 928 next to a Panamera to get a true perspective. The 928 was huge when introduced, especially compared with the 911 cars that shared the showroom at the time. Now, the 911 series cars are the same size as the 928, and the Cayenne and Panamera are the "big boys". The 928 front bumper hits you below the knees, for some perspective.

If anyone wants to play, I have a 2011 Cayenne S V8 engine, 70,000 miles with ECU sitting in my self storage. Got it when I bought my previous 2011 Cayenne S.

A good 'in the family' engine swap is the Audi V8. I believe it's the spiritual successor to Porsche 928's V8. It debuted as a 3.6L in 1988. It grew to 4.2L. Before turbo, it was able to make over 420HP in naturally aspired trim. This Audi V8 engine is extremely compact and light weight. Since I've disassembled both I can see some obvious and striking similarities.... it's clear some of the same engineers worked on both engines and may have 'fixed' all of the 928's V8's issues when they developed it becasue its generally considered highly reliable like the 928's v8. The Audi V8's most obvious difference is that's is very under square while the 928's v8 is very over square. In the under / over square battle for street dominance, seems like time and technology have made long stroke engines the winning formula for most road going vehicles.
Putting one in a 928 would take 100 Lbs off the nose and would add 100HP peak. It would also allow some weight to be moved lower and further back. The peak HP figures are impressive but the broad and useable power curve is what makes this engine a stand out. The later Audi V8's had an 5 valves / cyl and a 3 stage intake manifold and thus have a very broad torque line and rising power curve. (3500 to 7000 RPM)
