Fuel injector upgrade questions
I was having a conversation with my roommateand his father this evening (over some fantastic Cohiba cigars 
), and we came upon the topic of upgrading the fuel injectors in the S2000. He drives a '97 Mistu 3000GT VR-4, modded to around 400hp. Any further serious upgrades he wants to do will require an upgrade of the stock injectors, so this issue is of importance to him. He asked if I knew of anyone with upgraded injectors in a N/A S2000, and I said I had heard of none.
This leads me to my point:
1. What are the specs on the stock injectors?
2. At what point in a N/A application would the stock injectors no longer be adequate?
3. Who makes upgrade solutions for the stock S2000 injectors?
4. Anybody GOT upgraded injectors installed?
What?

1: Stock injectors are 360cc at 43psi.
2: I doubt you would need larger injectors in an NA application. Maybe if you go to some serious individual throttle bodies.
3: RC Eng make some injectors and kits to fit them in the S2000 intake, rail and loom.
4: I have 440s and they fit fine. But then I have an SC and E-manage.

RC, inline pro, summit are just a few companies that make injectors to fit the S. They come in many sizes. You can do low impedance with a resistor box which will give you a few more options. S2k injectors are vary similar to DSM injectors actually waiting to see if they will fit. I have a set of 880cc. I know Rc makes all the way up to 785cc with a map to make it easier to tune.My previous injectors were 550cc and fit with no prob they come with spacers. I have a turbo and aem ems.
