Tried to find this info, but had no success.
What size are the LS2 injectors? What N/A HP do they support?
What is a complete intake with rails and injectors worth?
Thanks for the help.
Phil

 

34 lbs/hr @58psi
about 500 fwhp

89017648 – LS2 intake manifold – 290ish
12570790 – LS2 throttle body – 360ish
12572174 – LS2 fuel rails – 150ish
89017587 – LS2 injector o-rings – 30ish
12569113 - LS2 injector (8x) - ???

Stock injectors on 2005-2007 LS2 V8 equipped C6 Corvette, 2005-2006 LS2 equipped GTO and 2006 LS2 equipped CTS-V as well.
The LS2 injectors flow 33.9 lbs/hr (4.27 grams/second) at 58 psi (400 kPa) fuel pressure.

LS2 Injector information
Bosch part # 0 280 158 049
GM # 12569113
USCar connector
65.2 mm overall length
52 mm O-ring to O-ring
4.3 mm tip length
15 degree spray cone
4 hole injector
high impedance

The USCar connector is not the same type of connector as used on earlier LS1 and other GM V8 engines so these injectors are not compatible with the older vehicles without changing the connectors on the wiring harness. The injectors are also shorter than the LS1 style injectors and the O-ring diameter in the intake manifold is different as well.
