i would rather not go with a converter box and what not, and am still running a stock comp. is there any disadvantage with running high impedance as opposed to low? im looking for 750 or so at the wheels with the s475, but then im goin to send it to forcedinductions to bore is out to a 88mm, and only want to do the injectors once! so how much will the 80lbs make, i run 47psi fuel pressure so really the 103's will be more like 90lbs. this is a ltx car.

They'll perform better than the commonly used low impedance ones.

at only 47psi fuel rail pressure....you will want to bump that up, c'mon where is da power.

get you some 75+ LB/hr fuel injectors and a fuel pressure regulator setup w/reference to the manifold & you will be set.
get your fuel pressure up to 58psi, you could go with a smaller injector if you do so

There's a Ford racing injector that flows something like 80 lbs / hr at 39psi.

The 80#ers are good for about 800-900rwhp depending on fuel system behind them and tune. Pump volume line volume and boost reference regulator make a big difference. Any higher than that to properly control the inj. you will want to step it to a high quality low imp. and a converter box.
