the injectors for the RB are the same as the SR. I also believe that goes for the KA and the V6 maxima.

So what exactly did he say the problem was with the o-rings? Mine look fine at a glance, but is there something I should look for?

Well i had 4 bad lower orings on the injectors. The shop told me that they did not replace the bottom o-rings the 1st time because they didn't have them on hand. I did not recall them telling me this the 1st time i picked up my rail. Anyhow, i have the company info and they can order the oring set for any of you interested. The specialists name is TRACY the shop name is Fuel Injection Specialist and here's thier info:

and here's a pics of my lower o-rings.

4 were bad. I think they messed them up when they re-installed them.

well i installed them and man is the engine pissed at me. I get boost and a real ****ty idle. Fuel pressure is at 38psi and stable. Hmmmmm. There was an *** load of oil from the engine on the right hand side. All pistons are firing and fuel injectors are working. Have no idea what caused the oil to jump out and splatter everywhere. I'm gonna look at it tomorrow when there's day light.
