Ok So I have the Typical D16Z6 Turbo Set-up. I know They can hit the 300HP Mark but I wanna see how close I can get to 400Hp. I need help choosing the correct sized turbo for my set-up to hit my goals with going to big and having sever lag.

My Current Set-up: All parts are new and motor and head are assembled(0 miles), but not bolted together yet, or Installed in the car.

Probably missing some things. As of right now I have an Ebay 57 trim/ .63 AR turbo. I was looking at the Billet series Precision turbos or the 5454E, 3231E, 5557, or the 5757 turbos to reach my goals. I just looking for a balance of lag/performance for this little motor. Didnt want a 6262 + and have WAY to much lag.

Thanxs
