Re: Injector size GSR turbo
450cc DSMs will be fine. If you have aspirations for higher boost, get 550cc (saturated) or larger (if you plan on high boost some day). No reason to install a resistor box if you plan to eventually upgrade.
Stock B series injectors are 240cc and are sufficient for atmostpheric pressure (1 bar). Hence, in theory, 480cc injectors should be able to run 2bar (1 bar boost, ~14.5psi). In practice it is more complicated than that, since we use over-rich conditions to cool the intake charge and prevent detonation, atomization/intake flow characteristics, valve timing, etc. But this can be used as a rough guideline. 250whp is more than attainable with 450cc DSM injectors.

240cc = 180-190whp 310cc = 200-220whp 370cc = 220-280whp
440cc = 280-330whp 550cc = 330whp-380whp 660cc = 380whp-425whp
720cc = 425whp-475whp 880cc = 475whp-525whp 1000cc = 525whp-600whp

440cc = 280-330whp 550cc = 330whp-380whp 660cc = 380whp-425whp
720cc = 425whp-475whp 880cc = 475whp-525whp 1000cc = 525whp-600whp
