haha nice reply wit the pic and all.

Ya 2" or i would do 2.25" just incase you crank boost later on. It doesnt really matter what size of piping you wont notice much diff in lag on the d series

Re:size of turbo piping?

I would probably stay with the 1.75", since the that's the diameter of the intercooler.

Changing pipe sizes will bottle neck the air flow. Then, coming out of the IC will slow air velocity, since it's a bigger pipe, and a sudden change, rather than a gradual change.

Sort of the same idea as when you port something..
