Hi, i have a 89 CRX with a 1.6 liter DOHC (engine code "ZC") non-vtec. I am planning on putting bigger fuel injectors on it without turbo or supercharger. How big would i be able to go? I would like to get as much horsepower i can with just bolt ons and such but i dont know how to size the injectors for max horsepower and tq. how is there such thing as too big? and the injectors i would be planning on gettting are BLITZ 660cc injectors. if this isnt correct, what should i use. and what aftermarket equipment would i need? Thanks for the help!
