You are going to need fuel management to control those injectors. Otherwise, your car will not idle under stock ECU management.

I would recommend either a standalone system, MSnS, or perhaps a secondary fuel set-up working with an SFMU to raise your FP under boost.

You can't just throw on bigger injectors, you need a way to control them beyond what the OEM ECU is capable of. I'm sure others who've upgraded fuel set-ups will chime in to give some input.

If you want to keep the injectors "drop in", you may want to get in touch with a place like RC Engineering; they have the ability to modify stock injectors to flow more. They say they can increase flow by about 50% over stock.

which would put our injectors at less than half the flow he wants.


There are plenty of injectors that will work. A quick search will give it to you.

Srt-4 neon injectors are the same from my research. I plan on getting a nice big set too so I don't have to upgrade later on down the line.
