I would really go with 550/890cc combo because I had 720x4 but it ended up creating all sort of flooding issues. the 550/890 combo supports teh same hp as the 720x4 but without the crazy big primaries. Good luck. I have no idea about the fcon, never used one.

Thats because you used an SAFC. They arent anything but trouble..

I agree, unless you are going to be running standalone 720cc injectors in the primaries is just way to much because the safc can't take fuel out on the initial cranking of the motor and that is where you will flood with the 720cc injectors and stock ecu with a piggyback. Archangels, you should be fine with 550s and 890cc injectors or what you can do is wait till the rtek 1.8 comes out and it will be made for either a 550/720 combo or 720x4 combo. The site for the bnr upgrades is. http://www.rx7store.net/index.asp?Pa...S&Category=364 and for the rtek chips the site is www.pocketlogger.com

well i wana run decent power about 15psi or so, keep in mind it's a street car with ocassional track ( drag ) use, i was hoping 720cc's would be enough, but now my question is, would my FCON automatically adapt too the 890cc's like it does for 550cc's or 720cc's, the computer automatically tunes itself so i dont know if 890cc's are out if it's league or not....
I see mild difference between BNR stage 2's and 3's.... if i can use 720cc's for either or i'll go stage 3 but if i can use them with only stage 2, then thats the one i'll go with....
guess thats my last question....

IF your harness is in good condition I woudl recommend the Rtek 2.0 when it comes out.
It will be like a standalone system but almost half the price.
I;ve heard 720's don't work in primary slots with piggy backs is because I think they use different maps on start up so the SAFC isn't working yet so the ECU is injecting 550cc pulses and not lowered 720cc pulses.
Jrat tried the big BNR and a SAFC. It didn't work out very well. :P

yeah, HKS does have a chip for their upgraded turbo kit, think its like a td07 or 20g or something, maybe you could tune from that, but thats still fairly ghetto
F-Con is great, but can't handle diff injector sizes like the S-AFC can
The S-AFC still can't control primaries at cranking cause theyre WOT and the AFM signal has no effect on that.
maybe see if you can save up and get a standalone or find a Power FC for S5 FC on yahoo.co.jp or something and sell your stock ECU/AFM/F-Con to recoop some of the money later.
You still have to pay for tuning and whatever else you need, but standalone is better.
and he has a 89 s5, rtek 2.0 is s4 only as of now

ahh crap....
last question i really need to ask is what turbo should i look into getting....
BNR stage 2 or 3....
my FCON i wana keep and upgrade everything later, and i'm sure the FCON will work with 720cc's in the secondary's just fine....
can i get away with 15psi boost or lower with the 720cc's on these turbo's?, if not can i get away with them using the stage 2?...

I repeat you should not run 15lbs on any turbo with stock ems. You will blow your motor. You don't have the timing for 15lbs and the stock top mount can cool the charge enuff. Damn get a aftermarket ems system or be happy with 10lbs of boost. Cut and dry end of story.
