If you are using an fmu 310s should be alright, but if your using uberdata or hondata or even an afc then id get 440s.

Re: (98TEG2NV)
330c c/min / 10.5 = 31.42 lbs/hr
31.42 lbs/hr * 4 injectors * 0.9 duty / 0.50 BSFC = 226 horsepower
10 PSI ~ 120 hp * (14.7 + 10) / 14.7 ~ 201 hp (rough estimate)
If you are going to be making only 10 PSI, and assuming the stock rev limit is kept, there is no reason 330 cc/min injectors won't work. However, if good tuning or a raised rev limit raises your horsepower to more than 226, you will need more fuel.
