2007 CTS-V, LS2, I believe the stock injector size is around 28lb. What would be the next size up injector that would fit the LS2? I'm not interested in the Ford Bosche injector. Thanks.

 

next size up is the ls3 with an adapter to fit in the ls2 rail.. they would be 36 but run at 42 due to the fuel pressure. The stock ls2 injector is a Bosch and Ford uses the same one in the cobra. Ford nor GM make injectors. They get them from 3 manufacturers Bosch, Siemens or Denso, You can also have your stock injector modified to flow anything you need for 200.00

 

Thanks. I'll contact you this week.
