My first question
 

May sound dumb to some of you, but here it is.
I am trying to purchase as many turbo related items as i can. i currently have what i believe to be everything but the ECU, fuel injectors, fuel regulator (is this one necessary?), and electronic boost control.
I have been reading on the forum how people are using rx7 and supra fuel injectors.On ebay they have fuel injectors running from 300 to 800 cc range, My question is this.........If i purchase a 800 cc fuel injector, can i use the same set up as the 400 cc fuel injector? or do i have to match the injectors with the ECU? I understand the ECU is programable, but to what extent i dont know.
I assume a 433 cc is safe since so many of you have done it and youtube shows a 300 version everywhere. Can someone help me in understanding the matchups here. Can the 800's perform the same as the 400's, will i get too much gas or is this something I can do for maybe future mods? My hope is I can buy a 500 or higher cc and not have any performance issues

With a programmable ECU you can use most low impedance injectors that fit the car.


Please spend a few more days studying what others have done lately. Normally, people would give you flack for such a rudimentary question. We will help you with the hardest things.
