Does anyone offer one? Looking around on the net I've yet to source one.

thanks

 

Custom.

But why? With turbo tech the way it is today, an appropriately sized modern turbo is going to be full tilt by 3500-4000, a couple hundred rpm behind a twin scroll design -- IMO its not worth the custom cost and that money could be better spent elsewhere. But, always interested in the name of hard data, so if you do go down that road please post some results.
