Replace Fuel Injectors? - ZR-1 Net Registry Forums

Corvettes White · 09-27-2014

I pulled the plenum off the top of my ’89 LT5 in advance of dropping it in the engine bay. I bought the motor used and out of the car so have never run it.
Question; what do I do with the injectors? I am apprehensive about just leaving them in only to find they are clogged, broken, etc. I can send them out for cleaning and verification or I can simply buy new ones. Heck, I am not even sure if the flow rates in the ’89 are the same as those in the ’90 and later motors.
It is not a question of cost or time here. It is long term durability as I intend to put 100,000 miles on the car. If I change the injectors I am concerned about the new flow rates not matching the existing and in turn having to retune the computer. I intend to leave the motor basically stock. I also need to deal with California’s pissoline.
Thank in advance. George
