What size injectors would I need to run about 280 whp on a 99 integra gsr?

Also, are Delphi injectors any good?

 

personally i would go with rc 750s for ease of future plans

on a budget, it can be done with just 440's or 550's

I made 240 with 370s on a b16 without a FPR... id suggest one if u want 280 out of the 370s... they will be maxed without a FPR

 

At least 550s so you can have more room to grow.
