GSL-SE Fuel injectors enough?
Lets talk fuel for modified rotaries. So an S5 engine with lets say turbo back exhaust, street port, stage 3 BNR turbo running 15psi, 255lph walbro. Would 4 of the GSL-SE 680cc fuel injectors be enough to feed this engine?
This is the setup I am doing right now. I want to make 350rwhp. Do you think it will? and how reliable will this car be running at 15psi on the street?

im 95% positive the injectors would be too small not, espically without a stand alone. reliability is a funny thing, its hard to say how reliable something will be, it depends on how well it was built. theres a car in town that has about the same componets on it as my car, and roughly completed about the same time, while ive had next to no problems, hes haveing problems almost every week. its ALL about build quality.

Not enough...
Do the math...
(680 - 550)/550 = ~23% increase, so this is also your approximate increase in power potential. Stock 4 x 550's barely can support 250 to the wheels, so 4 x 680's would be about 300hp potential. This is way short of the 350 you're asking. You can bump the fuel pressure up, and this can potentially gain up to 30% more power. If you can swing the money, go with 4 x 720's - these drop-in 720's can be had from any GReddy dealer.
