Just as it says I am trading in the bullet for a ss housing turbo, wondering what I should put as a primary. I got some options i was thinking about s400 s475 s480. Horse power goals is under 800 horse would like the quicker spooling setup and hard top end for some street racing or occasional 1/4. I am going to run the htt ss turbo as a single little bit while I buy the other stuff hows it going to run in comparison to the bullet. thanks for any advice dave
