What Injectors Are You Using On Your Rb20det

FOG35, i made similar to you 260rwhp(195rwkw?) on 15 psi. But realistically, im after 300rwhp on 18-20psi, dont think a fuel reg is going to get me there, i think it will be sorted with fpr, gtr inject (already got a gtr pump).

raZ1911 - yes a bad thing.

The computer will be firing the injectors at the same pulse width for all the injectors, so two larger injectors are going to let more fuel through in the same amount of time.

If there were such an ECU that could control individual injector pulse width - (MOTEC maybe?) tuning the thing would be a nightmare - you would want to be monitoring Air/Fuel ratios out of each individual cylinder to ensure everything was good.

oops should of made myself more clear i ment if you had say 800cc ones on a motor that doesnt NEED that much would it still do something? or should you just stick with only whats needed?

Ahh gotcha! You should choose injectors that match your application.

If they are too large you loose resolution at low pulse width - so your tuner will not be able to set the motor up to run as smoothly / efficiently at lower revs.
