Well, I cant prove it 100% , like i did it on my targa. From the research I have conducted, It appears that Turbo has different air filter configuration, hence the back side of the decklid is different. as far as the size, diameter is considered, they are all the same!

 

Quick tease pic....with 993 tips i am waiting on few additional parts and i think it will fit



ofcourse the C4S emblem will be deleted. i might even tint my bottom lights to match the painted reflector, and tint my windows ofcourse to match that blackout part. Well see. for now, fitting it in there is the main priority. Ill keep you posted.

 

Sorry to revive an old thread, but I was wondering if you ever got this completed/working before you sold the car?

 

Ditto here! Did it work? I am considering the same/similar conversion. 996TT rear deck with moveable Bi-Wing on a 04 C2 Cab. Not sure if there is a fitment issue with the Cabriolet.
