Injector swap question

IneedAZ · 10-27-2021, 11:20 AM

I have a good idea on the price of the injectors, does anyone know what the time the avg shop will bill for the labor? Is it a 4 hour job? What does GM say?

I would just plan on a whole day. By the time you pull the blower, change the hard lines, put in the injectors, reinstall the blower, purge the intercooler system, etc it's going to eat up most of the day.

I would quess good part of the day also. Are you going with a new pump on the high pressure side to feed those larger injectors? Also do the bigger injectors need a 38% fuel lobe cam? Asking because not sure.

Not sure about cam lobe..mine has the 38%. I am not planning on high side pump. Lot of cash for 10% or less gain. Was thinking of a 30% injector increase to give me more inj pw margin of safety. I would think it would get me back to the 5ms range.
