460cc injectors on stock pro?

[91ProtegeLX]

Would it be a wise idea for me to put in the 460cc injectors (n/z 2nd gen rx7) now with the small amount of mods that i have (see sig). WOuld it cause me to run excessivel rich? Or would it be ok? I need new injectors, and the cheapest price I got was $750 for all four. Which I think is ridiculous. I have the 460's sittin, as I am gonna use them when I get my turbo installed. Thanks

I would think that if you upped to the walboro 255 Lph or the 2nd gen rx7 fuel pump then you might b/c the pump is there to add the extra fuel through the bigger injector.

I would think that you might run a little rich but not too bad to notice on just the fuel injector upgrade

This is my guess. Anyone know better?

whoa... ummm yeah youd run richer than Boris Yeltzien's breath. as it is the stock injectors are big enough. upgrading them would only cause you more anguish than gain. unless you are going turbo, there is no need to upgrade injectors. you have a limited amount of air that makes it in as is, and stoichometric ratios play a huge part in our engines. find a way to get more air into your cyl before you even worry about fuel.

i vote waste of money.
