Doing an na-t build and I've been doing some research on injectors and fuel systems. A question I have not been able to answer is: what cc is too much on just an upgraded fuel pump and stock rail? I've been looking for 440s but they're either low imp or don't fit the sc. I've found 550s that are plug and play, would they be too much for just an upgraded fuel pump and an apexi neo? I wont be running much boost and my "goal numbers" aren't high enough to be significant.

 

Don't make the mistake and purchase eBay Chinese 440 cc injectors from eBay. Made my car run super rich. I went ahead and purchased my 440 cc injectors from O-side tiger. Plug and play for my na-t project. A little pricey but worth it.

 

I followed your advice with O-side Tiger and sent them a message. Did you get the 11mm ones? The site is pretty awesome.
