I've completed the big three. I will most likely swap my sri for a v2 and get a HFC a little later. But what now? Should I still continue to upgrade my air flow (bigger TB, intake manifold) stuff like that or just move on to a cam? Also how much gain could I expect from a good HFC?

 

a lot of people would probably say a cam but then you have to get better springs and retainers and a lot of work in labor and what not, i would say:

throttle body and a intake manifold

 

i had kind of the same question. i didnt know if once you start putting on throttle body, intake manifold, you would need to start adding aftermarket fuel components such as fuel rail, regulator, etc. to keep it balanced?

 

you dont allways need springs/retainers, or head work for a cam. The Crower stg2 cam is a good cam and works fine in a stock head.

 

that is another good point i guess it all depends on the cam you go with... what is your goal for the car are you going forced induction or n/a, that would make a pretty good difference on what cam you would go with

 

I'm going n/a. It is a daily driver. What stage should I get 1 or 2 if I do get one? I heard you had to change the idle for a stage 2.
