Hey I have done a search but nothing comes up. I am currently smelling gas under my hood, I am thinking my fpr and possible injectors are shot? Anyway since I am gooing to removed the uim I am thinking of upgrading my injector. First thing I am running a tunes M2 ecu, which I know will support the upgrade injector? I have seen 1000cc injectors and I wonder if those can work in the kg rail and will the M2 ecu work propertly with the 1000cc? Also in the future I thinking of getting power fc, but for now I don't have the cash so the M2 has to do for now, I am looking to make HP I just want to upgrade to something that is decent and saf, the rail. BTw does anyone know where I find the kg rail for good price that won't kill me? Also is the 850 top feed or side feed? thanks alot, khris

The 850s and the 550s are side feed. I do not believe that the M2 ecu can support larger injectors. If you're leaking fuel, I'd be willing to bet that it is either a fuel line, the fuel pulsation dampner, an injector o-ring, or the tops of the primary injectors. Unless you get it used, I don't think you're finding the KG rail for cheaper than keith is selling it. I would recommend just replacing whatever needs to be fixed, and not trying to upgrade anything yet, as it will be more of a headach than you want.

www.kgparts.com is the only place I know where to find Keiths rails.

The rx7store also sells them, but why would you want to pay for the middle man?

Hey thanks alot, guys I had replace everything already new back in 96 or 95 when my engine was shot, and I even got the injectors cleaned and balanced by RC Engineering, and it's good I did cause they found 1 of my secondayr stock closed? Have no idead that happen. Anyway I am not using the car it's put away but I want to replace the rail and change the stock fpr and I was thinking of going with a slightly larger injector, but I am not sure on what size to get because I not shooting for big hp.

larger injectors wont work with the m2 ecu... and the best place to get the rails is from keith himself, get intouch with him if you have any qustions
