Ummm I did say on a bigger better flowing Turbo NOT on a CT!
Some of the guys will jump in with what a CT will make at 12 psi but my guess is it might make around a 50% increase in power from your old NA if everythings done right!
Most of what you're doing is just a bolt in so difficulty isn't high, Hardest part is sorting the Turbo Drain as the NA block isn't drilled and tapped for it.
