who much hp can the stock fuel injectors hold up to on the kade? and how much hp will you get for a p&p head with no valve work? thanks

Probably around 230 for the injectors...and a P&P doesnt give you the same horsepower everytime...it varies.

so what is the next step up for the injectors, and would the stock ecu be ok with them?

Fast1One

Im pretty sure you can use the injectors off an SR...and you can use the stock ECU but you have to get it reprogrammed....Or use SAFC i believe...Try talking to BigVinnie hes the KA expert...

use the safc or get the greddy emanage... either way you will be able to tune for bigger injectors...

power levels from just a port and polish will not be that great... untill you get bigger cams and a bigger throttle body... the port and polish allows the incomming air charge to get in there faster and smoother... but you still have the same amount of air getting into the motor... you might feel a little power gain from the better breathing... but until you get more air and fuel into the mix you wont notice it that much... now that you have the head ported and polished get better cams and then you will feel the power you are looking for...

is the safc just as good as the greddy emange even though the greddy is a lot more $$ and wikd240 are you stilll looking for that head? my car will be getting out of the machine shop in about a week, and i will have the old head for sale. i was going to put it up on ebay.

the emanage has more options that the safc2 does not have... it will also allow you to run 2 additional injectors as well as the ability to manipulate the fuel and ignition with all of the add ons... damn near a stand alone but still a piggy back unit... tuning on a laptop makes things a lot easier than the safc2... but as you said it costs more than the safc... worth the investment when standalone systems are out of reach...

i got my head and the car is up and running... bout damn time... all is good so far... but anything is possible... there is always room for another head at my house... im working on the vg swap on a 240 now... getting everything together that im going to need so the ka build is on hold for a while... at least until i get tired of haveing a sohc motor in the other 240 i am going to pick up...

Duh, you're going to need 1000cc injectors.
