View Full Version : 2stage twin turbo

08-10-2009, 04:48 PM
Hi all,
I have a 2002 legacy B4. I love the way it moves. but it still not that much I want. all the time when I'm driving at 4500 RPM the car's getting more and more power.
what can I do to let the second turbo come in earlier than 4500 RPM?
are maybe let them boost together from the beginning?

can someone please tell me how to add more horsepower to my legacy?
for now it is standard.
