injectors,stock fuel rail question

i want to hit around 350-450hp to the crank.its a 90 turbo.i know the mods required.i just want to know with the stock fuel rails what injectors are going to be sufficent to handle 35-450 hp.i know most ppl do the 550/1600 setup.what other setups are there..
i researched a few setups...
4x1000=overkill for primaries is what i think
2x720 and 2x1000cc=?????
850x2(bored out 550's if its possible without injectors dribbling) and 2x1000cc=????

thanks.

thanks for the link i was checkin it out,one thing though.
since the 550's are high impedence can i bore them out to 850's without any problems..

850x2 and 1000x2 would be the best setup im not sure on boring out 550's to 850's though unless someone can give me more info..

thanks for the support..

first thing you need to tell use what ecu you are using.

and I wouldn't go over 720's in the primarys.
