your stock injectors will be fine, a fuel rail is a waste of money, and who needs a pressure regulator when you can wide band tune with a chipped ecu? so the answer is chip the ecu, and do some wideband tuning......you have any valve train work? if so chipping the ecu will be sweet so you can rev the **** out of it....oh and you should boost the ---- out of that thing if you really wanna go fast...

10.5psi is not considered "high boost".
..how much did you overbore? .25? ..that's -----. It'll be OK. Boost away!
As far as tuning, a wideband oxygen sensor is just that.. a wider spectrum sensor for detecting your air to fuel ratio. This will tell you how rich/lean you're running...

not 10.5 psi...10.5:1 c/r......and thats not to high to boost, a stock b16 is 10.2:1 c/r and it will hold 10 psi all day every day with a good tune...wideband tuning in a nut shell.....you chip the ecu, choose your editing software ( turboedit or uberdata ) and you can have someone like xenocron chip the ecu for you and make you a map as a means of a starting point if your confused how to, its $75, then a wide band is a new oxygen sensor, a controller, and a digital display, not hard to install but cost about $300, the digital display will show your air/fuel ratio at any given rpm, this allows you to make accurate changes to the map when your "tuning" it with turboedit or uberdata, all motor you want to see aggressive timing and probably around 14:1-15:1 afr across the board....dont despair after about 15-20 hours of resarch you will understand better, but you need to go to pgmfi.org and do some research...best of luck
