Does anyone know the stock injector size? Also what is recommended size, if upgrading intake manifold? or could the stock handle that much more air? One more is too lean bad for the engine?

 

what year/model?

 

2003 galant es 2.4l

 

The stock injectors should be able to keep up with just about any fuel demand you can give it with minor upgrades. Intake pipes, freeflowing air filter, and catback exhaust is what i consider to be minor.

I have already replaced all that. I am talking putting a bigger intake manifold on.

 

A bigger intake manifold isn't going to get you anywhere as your engine operates on vacuum. Even at 100% volumetric effeciency, it will only suck in as much air as it displaces unless you force it in (Turbo, etc).
