The 14B is a very capable turbo; My car has never been faster than when I was running a 14B at 20PSI with a rewired stock pump. *** Please note *** this is not recommended - I was just able to get away with it running 93 octane in my geographic area and temperature. I would recommend not going over 16psi and rewire the stock pump for re-assurance. I am assuming you have an open air box - if not that should definitely be your next mod followed by exhaust working from the muffler to the turbo. Good luck!
