Modify K20 need Larger injector? & how to choose?

[jesmine0]

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.

Some people choose to upgrade the injectors once they change cams.

On a stock engine with bolt-on modifications you shouldnt have to change your injectors.
