i have a 94 gsr with a b20 T3/T4 TO4E turbonetics turbo and other mods and it dynoed 250 at the wheels at 8psi. I was wondering what size injectors i would need to turn the boost up to around 12. Also, i have stock fuel rail, do i need to replace that too?

 

id say anything between 440 and 550 are ok

 

thanks

 

Just get DSM 450s. And no, you do not need to upgrade the fuel rail.
