Do they make these any more? All I see have the 68 mm turbine side now. Thinking about running a pair of them on the car.

Yes, that turbo is based off of a box unit from an L10 Cummins engine, so any of the typical S300 housings can be machined to accept it.

Smokem what kind of flow difference is there between the 68mm vs 71mm turbine in the same .91 housing?
 
The only supplied flow data for the 71mm turbine wheel would be with the factory option large AR housings, but in my opinion I highly doubt you would see more than 1-2lb/min difference. Do be aware that the turbine blade design between the 68/76mm and the 71/80mm wheels is quite different.
 
I was informed that the 68mm turbine wheel flows more than the 71mm wheel.

At one time, I ran a 66/71/.70 secondary, and I can say that between the 71mm and the now 68mm turbine in a T4 x .83 housing...the 68mm in a T3 x .70 was the most responsive of them all.
I also ran a 66/73/.80...but it's not even in the same spool up catagory....I'm pretty sure the Second Coming is faster then the 73mm turbine wheel in a .80 housing.

........But I would like to see the new 73mm turbine wheel design...
