370cc injectors

[hayato kazami]

does anyone know how many hp can gain by using 370cc injector in stock KA (stock ecu as well)???

Thanks

None...why would you need more fuel? The KA runs a little rich as is, adding more fuel will not net more hp...in order to warrant more fuel you need more air into the engine...i don't think they need to be upgraded for a NA setup at all, but definatly needed for high nitrous and turbo applications...hope this helps!

Yeah i added them in my NA KA when i was young and dumb....it just made my car run alot richer....hard starting sometimes...and a large amount of carbon build up...besides the stock injectors i believe are 295cc or close to that....but the way that they are set up theyare not flowing to the max and the 240 runs rich anyway

You're car will run rich as hell becaues youre ecu thinks its still only putting out 270cc of fuel, but instead its putting put 370cc. It would be a good mod if you have high compression, a bigger maf and throttle body. More air would be the only reason to add more fuel. Plus you need an Safc or jwt ecu to adjust for the injectors so your engine knows what its working with.

You of course had the ecu retuned right? Or at least a piggyback controller like an apexi s-afc?
