how much will it cost me if i get bigger injectors?? what are the sizes and which size is the best for the most power. I was wondering if i could put these bigger injectors before i upgrade my ecu, but keep my boost running at 11psi. Is that possible and what is the cost for bigger injectors, I will also be getting a fuel pump

 

it is not reccomended to run larger injectors without an ECU. even remapped Pettit and M2 ECU's are not made to handle larger injectors. in order to run larger injectors, it is reccomended to first have a standalone ECU, i.e. PFC, AEM or Haltek.

in any case...RC Engineering charges around $180 to bore out the stock injectors to any cc-flowage you want. most people go with 1200 or 1300 cc secondaries. you could always go with 1600 cc injectors if you plan pn having a really crazy (~500+ RWHP) setup in the future, but that requires a whole new fuel rail and new injectors, since the stock ones can't be bored out to 1600.
