I understand that once you get to a certian point in upgrading a FD, its wise to upgrade the fuel pump and injectors.


If you were to use bigger injectors on a bone stock motor, to support future upgrades, would this hurt the idle quality or driveablity of the motor, at all?

What about a bigger fuel pump? Would this hurt driveablity or idle quality of the motor?

From what I understand about the injectors, if you just run a lower duty cycle on the bigger injectors, they should have the the same performance and driveablity of stock injectors right?

 

If you go with bigger injectors you will need to control them with an ECU .If you have a programable ECU and you get injectors that are with in reason then you can go bigger .With the bigger fuel pump you will do better with an adjustable fuel presure regulator .

 

yeah I planned on using a power fc, and have a fair understnading of how all this works, but have never had a chance to play with programmable fuel injection in person before, so its these little details that nobody seems to talk about that get me wondering

So as long as I run a good FPR with the better fuel pump it wont hurt my idle?
