I say go for it, and if youre going to do it.. do it right with the V8 turbo from the Turbo, Turbo S, or the GTS
-Power for the GTS comes from an upgraded 4.8 liter V8 that makes 405 horsepower at 6,500 rpm along with 369 lb-ft at 3,500 rpm, up 20 hp on the S
-This time around, 520 hp wouldn't do, given that the face-lifted regular 2008 Cayenne Turbo saw a power boost from 450 hp to 500 hp. It only took a new intake system and a tweaked and remapped engine management system for the Turbo S to get another 50 hp for a total of 550 out of the new 4.8-liter, direct-injection, twin-turbo V-8. Torque escalates from 516 to an even loftier 553 lb-ft, available between 2250 and 4500 rpm.
The result is phenomenal performance. zero to 60 mph takes a claimed 4.7 seconds, down 0.2 second from the regular Turbo. Top speed increases by 3 mph to 174, making the Cayenne Turbo S the fastest SUV available...
AND IT WEIGHTS 5,600LBS!!!
Imagine that engine (2009 Turbo S) In a Boxster weighing about 3100lbs..... and what do you think the 0-60 times and the top speed will be.... ???
It just makes me want to think about doing this conversion myself if at all possible...
