what do you guys think about using the rebic to add fuel to a sinngle turbo RX7?

i have a PFC with 2 850s and 2 1300s and i also have a rebic 3 with 2 720s mounted on the greddy elbow.

My turbo is a T70 BB with a .84 A/R on a race ported motor.

Are the AICs too risky?

i got the rebic for a very good deal, and i think it would be better than spending about $700 to run 1600s with a new rail, FPR and fittings. because its only an extra 600 cc over my current setup, where as when i use the rebic i'll have an extra 1440cc.



and my other question is, can i use the stock FPR with the rebic setup and dual walbros??

Just as long as you can make it work, I see no reason why you can't run the rebic. Just seems like a pita having to mess with 3 sets of fuel injecters vs. 2.

I did this for a while before I got my 1680's. It works ok, but is a pain in the *** to get right. Get everything close, then dial it in with the pfc, not by adjusting the AIC.

i read about using 6 injectors with the PFC but it sounds like a PITA to make it work. and if i do it that way, is the PFC going to look at the injectors as 2 850ccs (primary) and 2 2020cc ( i.e 1300+720).

There are a bunch of people running 6 injs. with the pfc. If you are wanting to run the 2 injectors in the elbow before the throttle body it will not work very well with the pfc. Since you would be running the secondaries and subs at the same time, the amount of time it would take the fuel from the subs to reach the motor would cause a massive lean condition. Now if you run the extra injs. with an adapter that fits between the upper and lower intake manifolds running six injs. works very nicely.

Actually, plumbing the additional injectors into the upper intake manifold works well, I ran that set up on a TII with stock injectors, an Fcon, and a Rebic III plus simulator(GCC) It was good for at least the ~270rwhp I was making, for a couple years as a daily driver. Carl

I'm debating weather or not to go this route myself with a HKS AIC and the mazdacomp.com additional injector holder and rail setup.Just need some more stocker T2 injector if I do.
