Probably race gas also. A stronger DCT trans. A heavier duty 6MT clutch. Sounds like a very expensive project. I like to see other people do projects like this.

I personally would not bother with the centrifugal were I going for 800-900 rwhp. Turbo is the way to go for big power from a relatively small engine. I have had both on my 99M3, a Vortech T Trim running 16 psi and a turbo running 20 psi, but that car is a lot easier and cheaper to mod than an E90M3.
This^ But lets come back to reality for a moment.
