b16a2 drag kit with gsr cams. I was wondering waht size injectors i should purchase, i like the rc's. Everyone is tellign me to go for the 550cc's but i dont plan on boost past 7-8 psi for now. DO i even need them?

 

What are you using for fuel management? If your using something with high fuel pressures, 310 or 370's will do just fine. If you are using a standalone I'd go with 440's for 8psi

 

440cc's will be plenty with only 7-8psi. If you are planning on boosting more in the near future then going bigger never hurt anybody. For a cost efficient injector you might want to look into running the dsm 450's and getting a resistor box.
