Not had any personal experience but the principle should be the same as with any injector upgrade. Worth doing if the other parts of the boost and internal strength equation are right. I believe the 7MGTE squirters are a fit. They are the right impedance too, which is a plus. At 450cc they are less than the red denso rx ones but still lots more than the stockies (295cc?).
22psi! Bet she's fun to drive in traffic like that .
