"Why should I swap my D series out?"

[Shaved &/or Laid]

Alright since i slept through all this, i think what cash is trying to say about the boost is this:

to make more power from a d, you need a larger turbo. Larger turbo spools slower. (depending on bearings and trim etc, of course) Usually, to do something like double/ almost triple the power of a D series youre going to have to turn the boost up really high. BUT they are saying people are using 15g's...are they basically just going sans wastegate with these ? seems like 12 psi is pretty much the most a hairdryer that size will put out ?

im just asking for info really.

and, to explain my situation, i already had a blown D. I also didnt really wanna go the turbo route on whats basically my first car. So, preference being stated towards n/a setup, a B is a little easier to reach my goals.
