I've got a quick question for all the RB gods out there in nicoland. I work at a motorcycle shop and we have an account setup for RC engineering, and i get a discount from them. So i was going to order a set of injectors from them but when i looked at their site they had a bunch of different options. Do Rb's use Peak and Hold or Saturated injectors. Also what style tips and connector etc. do i need to order. Can you give me some info about this. I searched nico but didnt really find any info regarding the injector style.

RB20-25 use High impedance injectors. RB26 use Low impedance injectors. RB20-RB26 top feed and RB25 side feed injectors. Hope that helps.

The RC injectors i got used domestic style electrical connectors. I used some off a thunderbird from the junkyard(domestic style). The ones i got were supposedly for a honda k-series. The tips that go into the intake had to be filed down a little to fit but no big deal. The tips that go into the fuel rail were too big. The o-rings are 14mm i believe. I think the RB are around 10-11mm. Got a great deal on them so i made them work.

I knew they were high imp. but i wasnt sure about the tip style that sits into the manifold. I also need to know what style electrical connector to order. I remember some saying they got rc injectors to fit their connector they just had to order the right style. I have cut open my harness to many times,so replacing the connectors is not an option. Unless i can just take the pins out of the old connector and snap them into the new connector
