injector style confusions

the 560s might be usable if your willing to sell them off? 

the only issue im aware of with running too big of an injector is poor idle quality, but what i dont know is when people say too big are the talking about going from ~400 to ~500cc or going for ~400 to ~2000cc 

for the sake of confusion, my stock injectors are 210cc

I road tuned a supra that went from stock ~450 injectors to 1000's and then onto 2200's 6 months later and idle quality and a/f control was mint right down to 700rpm. I was a bit surprised.

No dramas with the denso 720 in my lancer either on a factory (tuned) ecu.

Take a look on trademe you may find some 450's or 510's cheap. 

Such as these.

I reckon my 560s are worth 150-160.

Yeah sorry mate nothing good. Problems with oversized injectors are with the ecu unable to control low pw well enough causing poor injector control. Most modern ecus have pretty good injector control. Another issue is poor injector data which leads to poor fuel calculations which leads to poor injector control. Which leads to poor idle quality.
