I just bought a NA s4 and i have been trying to figure out what way to go with this build. What should I do before installing it. I am already hot tanking the housings and rotors and thinking about 3mm apex seals. Can you turbo a NA? Any suggestions would help.

 

Yes you can turbo it, its a whole lot of custom work. Check out the FAQ for more information.

3mm is a waste unless your apex seal grooves are worn out of spec.

 

Thanks is there any one thing that is a must as far as engine?

 

Taking your time, and doing a ton of research to figure out exactly what you want to do with your build.

 

The easiest way to answer your questions is to ask three others:

1. What is your power goal?

2. What is the intended use of the car?

3. What is your budget?
