search, don't come back til you have done your reasearch.

hmm...well i figure this forum would help me, i guess not...you really dont have to be rude about it

ive done alot of searching....and i found them

 

you can get injectors from an sr20 as long as they are side feed(correct me if i'm wrong) they fit right in the ka.

 

that is correct. or you can use MSD style with a custom fuel rail. but you need to know if you have (new injectors) are high or low impeadance. if high, you can use them 12 ohms. if low you need an impedance matching. ie resistor box or pack of resistors. also you will need a feul controller either rom tune or afc to run the injectors. there is alot to learn before you just drop them in. that's why i said to search first. this is jut the tip of the icer burg. I learned all about it buy reading. you weren't the first person to want bigger fuel injectors. it has been discussed over, and over and over and over.
eric.

 

As stated already. Just find a decent set of SR injectors (370cc) Purple top. They are a direct replacement for the KA. BTW why would you need to upgrade? Planning on boosting?

yes sir....thats why i need bigger injectors...thanks guys

 

if your going cheap you can stay 270cc factory and a vortech fmu 12.1 disk can make 10 psi no problem i have done it close to a year on a s13 with a ka24de platform if you want a complete fuel system please refer to our website at www.boostdesigns.com thanks and let us know if we can help, if you dont ask questions you cant learn

 

I know this an old thread, but after searching I found that 370cc injectors are good to about 280-300hp, true?

Here's a tip: 1.5 * horsepower = fuel flow in cc.
OR: cc / 1.5 = max horsepower at 80% cycle duty

SO:
370cc / 1.5 = 250hp, give or take.

Also, I think RX-7 injectors are 440cc and are side-feed high-impedence, I think.
