My question is this, I came across some 3.2L Injectors from the Y32SE, and was wondering if installing those on my 3.0 X30XE Engine with some Throttle body Porting will increase HP in any way.

If the fuel pump provides same PSI to the injectors and the pulse is the same then the injector should squirt just a bit more fuel.

Correct me if I am wrong but is the 3.2L injector rated at 240cc/min while the 3.0L is only 225cc/min?

I believe that if I can manage to get some more air past the throttle body and match that with just a bit more fuel, the car should still see AFR of 14.7:1 and everything else should remain unchanged.

Please let me know if those injectors are compatible with the system.

Also would this really work or will the ECU simply adjust the values and bring back everything to stock making the entire deal one very worthless experiment.

I doubt there's much if any difference in flow rate between the two injectors. In fact, I believe the 3.2 injectors run at a higher pressure anyway (3.8 bar IIRC) so, at a given pressure, they may flow less.

In any case, this is irrelevant because the engine's block learning will soon compensate for any changes and you will end up with the same fuelling as before.
