I always wanted those aem stuff, just for engine bay dressing lol, but then i just don't want to spend for them. Yup that's true, i have read that for n/a you don't need injector upgrades in our engines unless you are doing a serious hi-comp build. And yes, aftermarket regulators are also not needed. Pump, why not a Walbro 190lph, but then that's also not necessary. Not gonna race? No drags?
