			It is an increased HP kit for the engine.  The contents of the kit are not defined.  I know based on earlier kits, they definately had different camshafts.  I would not rule out new pistons, but there isn't a listing of what is changed in the dealer order guides. 
		
	
		
	
			
			
		
		
		
		
		
			FWIW, it is a $16000 option. AFJ

			May'be that would explain why the car with the X51 option seemed to have a noisey valve train also?

			Go to rennlist.com My buddy has a 2003 996 x50 he said it is upgraded turbo and was told tranny until it broke and found out it was the same tranny  as a stock 996 also the muffler has baffle removed. Thats about it no head work or different cams. Has carbon package cost the same as the x-50 option 15k. In 2005 the turbo s is the X-50 they made the car with all the pre x-50 option.

			Umm... a 996 TT X50 is a 996 TT with a GT2 motor. 
		
	
		
	
			
			
				
					Yes, it has the same transmission as a regular 996 TT So does the GT-2 AFJ
