Was told I could send my fairly new stock turbos(K-16) to a company in California and he could enlarge the intake side to a K-24 and leave the exhaust side alone. Any problems with this just being a simple bolt off/bolt on? Do I need to change fuel management? I do have in the car Dan Patrick's ECU upgrade and muffler delete....do I need to put on the cat bypass setup from Fabspeed as I would think this stock restrictive exhaust may be a problem....any help is GREATLY appreciated...Steve C 97 993TT

 

Best to ask this on Rennlist.com Lots of 993 turbo action over there... very little here.
