twin turbo 5.0

Hey guy so i have a complete twin turbo kit, still in the process of installing it right now. Just want to go over some things to get a complete rundown on everything that is going to be done. So currently the motor is rebuilt, all new bearing and forged interals in an 89 block. Gt40p heads...

I have a 5.0 with forged internals, gt40p heads and intake with a 80mm throttlebody and a n41 cam currently, its running 9.5:1 compression which isnt high but i found a twin turbo kit i want to put on it since its a quick power adder without having to stroke it, now I know I'm going to have to...
