Is there anything to be gained by changing out the stock injectors to larger ones on a N/A engine. As for mods a Spoon Snorkle, gutted and insulated airbox, 70mm TB, intake manifold ported and polished ot match the TB, Hondata gasket, Berk header. Will complete exhaust once I find what I want.

My goal is to buiild out the engine without going F/I.

Thanks in advance

None. Stock injectors can support over 350 WHP when using a AEM EMS to drive them, on a FI application.

I don't think you will make any gains.
You could get a fuel pressure regulater.
And tune that to get lil hp. With the gauge.

you wont gain anything unless you are boosted

To make more power, the engine needs more air.

The ECU adds more fuel when the MAP sensor detects more air being breathed in by having the injectors open for a longer duration. Only when the injectors are open "all the time" do you need bigger injectors, or a higher fuel pressure. Both modifications can also have their downsides at lower rpm / power levels.

As someone said above, the stock injectors seem to give you enough fuel for 350hp (can't confirm that but sounds reasonable), so there's no point in changing them out unless you are going higher than that.

Basically, adding more fuel is trivial, but adding more air is very difficult.

what about spraying it????

when you spray with a wet kit, you just need to upgrade your fuel pump. everything else is fine. i ran 100 wet shot and its perfectly fine
