Do NA's have 2 different injectors?
 

Are all of the injectors on a 91 NA the same? They all look the same and have the same numbers on the side. I was just wondering if there might be a difference between the primary and secondaries. I'm sending the injectors to R.C. engineering to have them cleaned, is there any specific info I need to give them?

They're the same. RC should know what to do with them.

As long as they are stock, they are all the same between the P and S. RC will know what they'll get and/or figure it out.

Thank you! Called R.C. and everything is ready to roll.
