1. Select your compressor cover, you have 2 options to go with. We have the 4 inlet Anti-surge cover with the 2.5 outlet. Then your other option is the On 3 Compact Cover which is a 3 inlet and 2 outlet.
2. You will need to make your decision on either a Journal Bearing or Ceramic Ball Bearing. Ball bearing is always going to spool faster and provide more longevity when put in situations where you're spinning the turbo hard for long periods of time.
3. Cast wheel or Billet wheel. Billet wheel is going to make more power, it is an 11 blade billet wheel, the shape and curvature of the blades can be much more precise on a billet piece vs a cast piece. This allows for a better design than the base cast wheel.
4. Select your exhaust housing and you have a few different options. The base pricing is setup for the traditional cast .63ar housing with the 4 bolt outlet design.
5. Lastly, you will need to make your decision on either a Journal Bearing or Ceramic Ball Bearing. Ball bearing is always going to spool faster and provide more longevity when put in situations where you're spinning the turbo hard for long periods of time.
