anyways yes you will lose some torque!!! 3" TDs way too big for na and prob overkill for turbo too. Idk anything about superchargerd Z so cant tell you much about it. For NA 2.25-2.5 is ideal if you got TD. 2.75-3 if you have single.

If I were you I would get something that works best for NA first then another one when you go FI.

I bought my greddy dual turbo ti-c a (2.75 TD)few months ago thinking I'll go FI soon but now I regret it lol... idk how much tq I lost but I think I lost a decent amout....................

I think its overkill to run a 3''dual on a supercharged VQ, and also you need back pressure with the supercharger.
