there are variables here.
I'm guessing you're going boosted, so what size turbo? How's it being tuned? Are you trying to use stock fuel pump[hope not] or are you planning on upgrading? If so, what pump do you plan on using? What compression do you plan on running? We basically need to know every detail of your engine to help you determine correct injector sizing, because contrary to what most people will tell you, there's not a 'one size fits all' for a given HP level.

get some 550cc

Bad idea. 550s will NOT fuel enough, I'm at ~80%DC on mine right now in the mid 300's on a 2.0L engine.

ok ok 750

why not just get 1000cc injectors and not worry about anything now or later?

I agree unless you are worried about an injector driver given they may not be saturated. Peak and hold style.

Most aftermarket injectors are. Resistor box is easy to wire up.

I vote for 1600s. When i first started turboing my car i had 450 then i wanted more power, i went too 880, then i wanted more i went too 1000, then i wanted a hell of alot more then i got 1600s.So you se the pattern once u start your always going to want more, so start big!!! hahaha

LOL, thats exactly what happened to me started with 450, to 550, to 880, to 950, to 1000, to 1600....
I would at least get some 880's....You dont wanna get a small injector and have to run higher fuel pressure just to make up for the difference...

bigger is better

1000 sounds good for what you are doing. Either way a set of injectors will cost the same. Hell do 1200, they finally dropped the price of those.

I think 750ss's should do just fine.
