Fuel Pump And Injectors ?

I have 2 questions.

Anyone know the stock HP capacity of the factory fuel pump on an 01XC70?

Are there any larger oem style direct fit injectors available besides the green ones?

I'm just trying to be frugal with my budget and spending $450 on injectors from viva doesn't

seem logical=P

I found these but I'm slightly skeptical. Would buying these be a good idea?
