Default Stock Fuel Injector Size VR4?

I was wondering what the stock injector size was for a vr4?

My vr4 is at 14 psi right now and I'm guessing its starting to push the limits on the fuel capabilities. I was thinking about upgrading the fuel injector size to 550cc. Any opinions or recommendations would help. Thanks

360cc if you haven't upgraded your turbo's you will not pust past the limits of them. Unless they're bad.

Oh ok. On another one of my posts someone said that with 14psi its probly pushing the limits on the fuel injectors and the fuel pump. But they are stock turbos

You might want to upgrade to a walbro 255. I'm not really sure where the stock pump runs out.
