Hi, Just wondering is all RC injector are suitable for honda like Denso or Bosh top end, or only Honda top end will suitable for Honda?

Besides, I had a k20 with intake, 2.75" exhaust, fuel pump and kpro (untuned but loaded calibration myself). DO I really need a Larger injector?

Cos i am looking of upgrade to 420cc injector but the injector is off 4AGE top feed engine. So not too sure if it would feed honda.

Cheers.
