Ok so here's all of the parts i've collected so far:
bonez 2.5" downpipe
bonez hf cat
bonez connecting pipe
Innovate G2 with LC1 WB O2
Knight sports FBCD
Apexi S-AFC2
Defi Boost gauge

parts on the car when I got it:
Apexi N1 duals
Apexi Power Intake

1. I've heard from a bunch of people that they hate FCDs and the S-AFC2. But I figured with my close to stock setup I'd do pretty well with just the S-AFC2/FCD. What do you guys think?

2. My eventual HP goals are around 250-300. No more than that. I'm taking a wild guess but I guess I'd get like 160-180 with this current setup? (no clue actually) My question is, is it possible to get 250+ and also pass emissions? According to reted's upgrade path, it's not. Is that the final answer? (lol waiting for reted to pwn me)

Thx.

dude if you want power....gotta deal with bypassing emissions or drop a v8 haha

btw since ur a s5 turbo pushing those mods, if the cars been tuned at all your obviously over 200hp (stock is 200 haha)

I'm gonna try to hit 280 max

I'm thinking something along the lines of bnr stage 1 + 3in piping all the way back from the turbo and supporting mods like a fuel pump and bigger injectors with something to control them (maybe power fc or rtek when it's done beta testing)

still debating if I want to keep my emissions or not but I need to get my car running right first (damn those vac lines to hell, reason why I want to delete emissions period haha)

you missed the two all important modifications.... they are NOT support mods, they are NECESSARY modifications if you plan to make that much power on a "stock" setup:

Fuel Pump
Fuel injectors

No sense installing a S-AFC if you've got no fuel to control.
I'm running a similar setup now, and it worked just fine up until the motor blew. haha.

Your car runs on dreams? If you are getting an SAFC, get a wideband so you don't, well, blow your motor because you only thought you knew what you were doing. The ECU pushes the injectors to 58% of capacity stock. Up that to about 80-85% safely. But after the SAFC pushes your stock injectors to capacity, if you want to go faster, you need to either remove things that bog the engine down or give it more gas. If you do all your free mods and remove all your emissions, then get yourself a ported intake (guess that's a freebie too) and a nice MSD ignition, then worry about your fuel system.

What does YOUR car run on? I agree to get a wideband, that is a must. And if you do get that wideband you will find that when you do all those mods like an intake and an exhaust, etc... YOU WILL BE RUNNING LEAN. I'd LOVE to see where you got those figures for the capacity of the stock injectors cuz everything I've seen tells me that the stockers are barely able to keep with a pure stock setup. Why do we have bigger injectors than N/A's? Cuz we got turbos. Would conservative mazda engineers put more fuel than necessary in the system? No. No need for an ignition either, since the stock one is good up to around 450hp or more, that is a waste of money. Don't blow your motor up. get a wideband, more fuel, a boost controller and tune w/ the S-AFC.

250whp is very hard to reach on a stock turbo.

I do have a wideband, and I listed it in the parts list lol.
But ok, the verdict is that I need the bigger injectors and fuel pump immediately? I knew I'd get it eventually, but I didn't know I'd already need it with minor exhaust and intake mods.

you should do some research on the stock fuel pump and learn why it's a good idea to upgrade early or making it one of your first mods

fuel pump needs to be upgraded and rewired first. Stock injectors need to be cleaned or replaced.

They are working on an Rtek chip for the s5 turbo. PM Henrik about beta testing. That will help control upgraded injectors.

Hm ok cool. I pmed henrik about the beta testing. Also I guess I'll be looking for 4 720cc injectors and a walbro 255. I'm guessing the walbro is a direct dropin and shouldn't affect anything or flood my engine correct? It should provide the same flow that it's providing now? The injectors will cause my engine to run rich cuz the pulse width will be the same and the engine won't know, but after installing the rtek it should control 720 720 properly. So instead of risking ruining my HF cat, should I just wait til I get the rtek, walbro and 720cc injectors and then throw everything on at one time? Or is there a step by step that would be good for my components?

what he means is sale a blown rotary engine as "Rebuilt" and use that money to susport the V8 swap

BLK FC3S

My old set up made 215 to the wheels.
S5 TII rebuilt stock port RA seals
stock turbo untouched wastegate (12psi I think)
3" turbo back exhaust, intake, fmic, and walbro fuel pump only mods.

160-180 for your set-up I believe is way underestimated unless you have bad compression.
You need to at least get a fuel pump (walbro or supraTT) on that thing before anything else.

How about starting off with a good base and getting a tune up first?

ProjectRE

U think i really need it ur money to get a v8 swap huh, i have more money then u, I don't need to steal from a cry baby who blow up his motor, plus i have 3 rx7, and 2 v8 Ls6 motor...

How the hell did i rip u off ur just a kid who don't know how to install a rotary in ur car, and blow up the motor ur self, even if u said that i sold u a blown motor, B&B Racing was going to rebuilt it for u for free, u never contact them ur pick up there calls, u know ur scary to talk to them cuz u **** up ur own motor ur self.. so quit being a big baby.
