ic piping size
ok i thought picking up some 2.5" piping for my d16y7 with a small t3 was a good idea.... until some guys said that 2" would be better with the smaller turbo and stock motor... is this true? should i have opted for the 2" instead of the bigger 2.5?

Re: ic piping size
think air flow. bigger pipes will have more flow capacity(volume). smaller pipes will pressurize quicker reducing lag because of less volume. you should *try to have the turbo and pipes matched to how much your head will be able to flow.
anywhere from 2 - 2.5" is good. if you're going big horsepower like weir^^ go like 3" or so

2" is the way to go
look at the area of these pipes
A of a 2" circle is 3.14*1^2 = 3.14
A of a 2.5" circle is 3.14*1.25^2 = 4.90 (thats a lot more area)
A of a 3" circle is 3.14*1.5^2 = 7.06 (thats huge by comparison)
i wouldn't use anything over 2.25" unless i was shooting for 350+ whp.
