If you simply do the math, you'll have your answer
350whp x 6cc/whp = 2100cc total
2100cc / 4 inj = 525cc for gasoline
Since E85 requires 30% more fuel for the same power, you multiply by 1.3 and get 682.5cc.
The math here is purely a method to more accurately estimate your injector sizing. Based on that, i would go with an 880cc injector. A set of 880s on E85 will allow you to make in the low to mid 400whp range.

ID1000s are perfect... never met anyone that was content with making that level of horsepower because they later always try to make more... its also not a bad thing to have a low duty cycle on your injectors... more room to avoid error...

yeah really. ive seen a few posts recently that allude to people washing rings if they have too big fuel injectors. that is completely not the case if it is tuned. one of y friends cars i tuned last year is using 880s on a b16 pushing 9 psi likely around 270hp. no washed rings there, the car runs great. i use the same precision 880s on my car, 475hp. no washed rings there either. both cars are tuned on neptune.

Even after my post above, i would still recommend ID1000s...they'll be more than large enough for now and for the future AND they'll idle like stock (provided you have the right tuner)
