Ka-t question

They're still not big enough. You need s14/s15 sr injectors which are 440 for that kind of power.

the rb uses 370cc injectors which are good for about 320whp on that motor. granted 2 extra cylinders but same displacement. the 370cc will make the power, but they will be running right close to 100% which is bad. its really a question of how cheap you want to get.

Think about bore and stroke though. 300zx having 370s around that power level
too but they run out of fuel.BUT with more cylinders you need less fuel to make more power. Thats self explanitory. You cant compare RB or VG to a 4 cyl. Fuel trims will always be different.


You will flow more cfm through a ka turbo car. Anything over 250hp I would get 440s or some cheap 550/650.
