I just bought 07cobaltowners turbo kit and it comes witha special intake hat complete with a single 60lb-hr injector. But someone told me to use the 2.0 sc injectors what size are those?
Thanks

 

Stock 2.0L injectors are 34#/hr.

 

is this an ls, or an ss n/a?

 

That 60# injector should be the fifth injector, if it came with the kit I'd use that one.

 

then it should have a piggyback, right?

 

yup, sounds like the Alpine turbo kit

 

Just buy hptuners, keep the 5th injector in but dont have it hooked up(so you dont have boost leak). Buy some 32lb(stock lsj) injectors and tune with hptuners. If you plan on pushing more then the 7-8psi its set for, buy some 42lb'ers and throw them on. I believe that kit is non-intercooled right? So you dont really want to push anymore then 8-9psi. You should be fine with the 32lbers. Your IDC's may get a little high tho, so running 42lbers wouldnt hurt. Car should handle 9psi no problem =P
