What do you think?

You cant hurt my feelings. It would still be Porsche powered (unlike the 914's I have built with SBC's in them)

Thoughts?

I like the fact of using a Porsche engine vice an LS V8 or an Audi engine, but my personal opinion is that is would change the character of the car too much.

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... :dance:

Sounds good to me. If you do it, let me know. I'll be your first customer.

Brad, did you ever finish this project? Do you now have a running Boxster with a Cayenne engine in it?
