66/88 on the comp wheel. I knew that the other day when you called but for some reason I thought you wanted turbine exducer and I couldnt remember it off the top of my head.

 

Farm, if you want 400 reliable, the D66 is your answer. I did 377 on a stock turbo with the mods in my sig. But that was before the hot IDM. So I would say it's very close to 400. And I didn't have any towing problems at all. You should be able to get there alot easier with your s2's. Call me crazy. Get a D66.

 

Beans, I just wasn't exaclty sure what the measurement for the impeller side was. So that was mostly my fault. Thanks for the specs.
