Thread: SR20 injector Size?

now this is the info i was looking to get.. thanks

If injectors go bad or out you will notice for sure, not to say that 150k mile injectors are going to be perfect. You could have them cleaned and flow tested if you are really concerned about the quality of your injectors. You are way over thinking bolt ons, do some research and go from there.

The 259 injectors are good for about 175whp, and to achieve that your going to need all bolt ons and a little internal work... then if you decide your going for more or possibly the duty cycle is near 100% and your going to upgrade your ecu id upgrade to 333cc(VE injectors) or 370cc(DET injectors)....


To answer your question, if you hqve a bad injector you would be.ok with replacing it with a used one Nissan injectors are.pretty good and don't go out too often....

Thanks for the correction, I must have been thinking in 4 bar numbers . Even though 370cc injectors are still cheaper then an Adjustable FPR
