The OEM studs are plenty strong for the header. You will be fine with them.

So how far can I go on 550cc injectors on e85? Im guessing the 1000ccs are pretty much mandatory?

I know for a fact a car doing 440 WHP on E85, using 540 CC injectors. I would not say the 1000 cc's are mandatory.

Those injectors are maxxed out then and it will take a shit anytime

Hes buying the kit new so for 180 more he can upgrade to ID 1000cc

They are not maxxed out meaning they not at 90% or more duty cycle. Its dependent on the tuner. If the tuner uses the DI system, there is plenty of room. If the tuner relies much more on the PI, then yeah they will be a problem.

Having too big of injectors is also a problem. When they are too big and duty cycle falls too low, they start to be inconsistent (drivability issues might arise). I wouldn't go past 700 cc unless shooting for over 600 whp. Just my personal opinion.

Now when the choice is either 550 or 1K the choice is tough and I might be inclined to go with 1K.

I already have the premium kit installed, im just picking up the fa20 flex fuel kit and wondering if the 550s i have will be good for 400whp.

Ask Toni himself.

You would be maxed out with the fuel system. We recommend 1000cc if you are running e85. It keeps the duty cycle down and everything happy.

I've been doing a lot of research on the BRZ Turbo kits, and the engines themselves, and come summer time when I buy a new BRZ, I will be purchasing the premium stage 1 kit from FBM that day. Up here in NH, we don't have E85, only 93 octane, and 1 gas station that sells 100 octane fuel.. (for $9.99/gallon).
But I am pumped, and can not wait for the summer to come, for me to grab the BRZ. I've driven one so far, and it's fun, but just too slow for my liking, so to slap a kit in here, and get an extra 100whp, I'll be thrilled!

Just curious, to anyone who currently has the kit installed, how's it holding up? Any issues with the car, at all?

ain't that the truth. with my dw900's ipw is never more than 4-5ms. low speed drivability and tuning the super-low end of the range has been a nightmare. tip-in tuning is touchy as hell (and can't be 'perfect' at low throttle deltas without dipping below the injector's minimum open time). i'm actually considering swapping them out for some 700's.

there is a definite downside to bigger injectors. bigger definitely isn't always better.
