If you plan on geting RC 550, and have after market fuel rails, like AAM make sure you get there full length style, NOT the Nissan 350z or Infinity G35. To avoid the machined and pressing the tops back on these injectors.

Kevin, that's not correct. The 350Z/G35 specific RC injectors are designed to work with any fuel rail, including AAM, CJ, or stock. There should be spacers included with your injectors, that need to be used to insure a proper fit on the rail. The injector pictures on the right is the correct injector for the 350Z/G35. Just dont want people getting more confused.

 

I did a search for them and can't find a site or anything.

Thanks!! Not sure why I couldn't find it when I searched the web.

 

Got the new set of x6 550cc full size today. Went in just fine with spacers on the AAM rails. No leaks, no stuck units, Thanks to RC they were very fair to me! I sure the hell will never use a RC Nissan type 550 injector!!! (smaller version)

 

this topic is confusing. Is there such a risk for RC750s too? I assume there is but..

 

DEatch work is just a oem 350z injector machined out to flow more fuel, thats why half the cost.... RC makes their own injector.

 

I don't understand why everyone wouldn't go with thier injectors. Technically they use stock injectors machined to flow more. Plus they cost much less.

I come from the DSM turbo world, FIC injectors are very popular there, but I didn't see any listed on thier website, is it hidden somewhere?

 

altered atmosphere has installed 1000s of injectors no failure per mike

 

Found this thread just wondering how did you determine that the injector was stuck open? I just installed 550's on my car and right when it got on the dyno it starting having problems. My car smokes right when I start it now. Did you pull all your injectors and just look at them? Secondly Kevin, How can I determine if these are the short or long ones you refer to? I got these used so not sure. I also didnt get the spacer so made my own with washers...... Let me know your thoughts

Thanks

edit jsut wanted to add I have a stock fuel rail....

 

I found this thread though searching. i'm wondering the same as roger about stuck injectors.anybody? thnx
