Fuel injectors


Recommended Posts

My injectors are at 85-92% duty cycle, so time to upgrade the fuel injectors before the next performance upgrade.

OEM Cadillac STS-V 4.4L injectors: AC Delco 217-3076 which is GM p/n 12598842 and Bosch p/n 0-280-158-085

ZR1 Injectors: BOS 0-280-158-187

Bosch injectors at 43.5 psi (3 BAR) flow 48.9 lbs/hr or at 58 psi (4 BAR) they flow 56.4 lbs/hr

PGA2B: I run Ford Racing 73lb injectors in my V. If the GT500 injectors are the same size and I suspect they are, then they will work. Mine are the M9593-LU60 so if you get the dimensions of those and compare to the GT500's you'll have your answer.
