I would look toward a 64/68mm or 66/68mm with the 0.80AR(14cm) turbine housing.

 

Don, Why is the 68mm trim better than say the 71mm used in the BD Special?

 

I don't believe the 5.9L has adequate displacement to drive the 71mm turbine properly for most street applications. I know there was a 64/68mm charger tested over the weekend @ BD, a small issue with crossloading the bearings was noticed, but nothing upgrading to a 6-pad would not fix.
