As far as i know its a standard cam, ive not had that apart. And i dont know about the sizing, i can have a look on the turbo tomorrow.
I expect it to be laggy but have good gains when it does kick in.
My exhaust is a big bore 2 piece system, its a sidey but im not sure its standard at the turbo end.
The elbow you get with the turbo is obselete, its 1 piece welded down, Im gonna have to cut that last bit off to accomodate for the scooby part
