Most use the TR6 or the BR7EF. I use the 7s. The debate could go on for hours between the two.

The nitrous guys usually run the 9s. Anything colder than the 8s and I've had pretty bad idle quality from them. When you have a big cam nitrous setup, you don't care about idle.

They seem to be good out of the box to a little over 15 PSI in most setups.

No one can answer this question without knowing your power level and a little about the setup...
