s30kid Posted November 11, 2013 Share Posted November 11, 2013 hello hybridZ I have a ported intake with a 240sx TB on it left over from my old motor. I swapped motors from stock to a f54 n47 flat top 10:1 setup. I want to swap over my 60mm TB to my new motor but i'm afraid that I might run too lean with the stock ecu. Do you think this will happen or am I in the green? Quote Link to comment Share on other sites More sharing options...
NewZed Posted November 11, 2013 Share Posted November 11, 2013 The throttle body just lets air in as the engine tries to pull it in. It has nothing to do with the air-fuel ratio. You may not be in the green, but the bigger throttle body will have little to do with the red. It will probably just make the motor feel more responsive, or more boggy, because it will be like stabbing the throttle from closed to wide open. It will be more switch-like, than progressive.
