Using 4x Bosch blue-top, high-Z injectors from miscellaneous VW. I believe they flow around 19lb/hr (~190cc). Measured resistance across injectors at 14.5ohm. Fuel rail is VW stock from later Digifant equipped cars, so it's a direct bolt on. Stock fuel pressure regulator from same fuel rail. I have no idea what condition these parts are in, so I will have to do some testing to make sure they are up to spec.
Injectors are wired seperately on injector channels A..D. Flyback is on pin 23.
