I have recently discovered that my injectors were leaking gasoline onto the intake of my engine. I have been browsing for some new ones, but all I am seeming to find are around 390cc and larger. I read that the stock size is 240cc. I have been told that I can use a bigger injector at the price of fuel efficiency, but I will notice a gain in HP. Is the gain substantial enough to sacrifice that in my daily driver? Or will I simply be flooding out the engine because I will have too much gas and not enough air to burn it? I'm guessing that I would generally only need larger injectors if I was building up the engine and planning to turbo-charge it and all that, but pretty much a stock rebuild is all that I have planned since I got another car for that kind of stuff. Any help will be appreciated. Thanks guys.
