1500cc - Supra TT top feed conversion

The 11mm O-rings seated perfectly in my fuel rail, and the high impedance design meant no resistor box rewiring headaches. Took about an hour to convert from side feed, and the car idles smoother than before.

Swapped out my old 680s for these 1500cc Bosch units and the idle is surprisingly smooth for such big injectors. The EV14 high impedance design made wiring them in straightforward with no extra hardware needed.

The 11mm O-rings seated perfectly in my fuel rail, and the high impedance design meant I didn't have to swap out my ECU driver. All six injectors arrived flow-matched and dead quiet at idle. This conversion took all the guesswork out of my top feed setup.
