I am wanting to get new injectors. I assume there are 4 of them. Where is a good place to get them? Are they all the same or are the pairs different?

91 NA

 

How many miles on them? Best bet would be to have them sent out and cleaned.

 

About 140k miles. I just called RC engineering and am going to send them out tomorrow for cleaning and calibration. Are the primaries the same as the secondaries?

 

no

you have to take off the intake to get to the primaries. the mount directly on the block.

 

RC does great work. I just had them clean mine last week.

 

I meant are the primaries the same model number/cc as the secondaries? Do I need to note which injectors came from where?

 

Taken from the sticky towards the top of the thread page. If your injectors are the originals they should be the very same.


What size injectors does my RX-7 use? What colour are they?
