You're forgetting this:

I started out talking about streetability.  

Are those 300+whp KA-T's you spoke of driven everyday?  How many miles have been put on them since they've been turbo'd?  Anyone can claim having a daily driver, so this doesn't matter, either.  As for reliability, how long will those stay together?

Also, are they COMPLETELY stock?  Headgasket and all?

You're not building your bottom end, and not replacing your clutch, and you plan to have an honest daily driver?  
Good luck with your car.

"treet cars generally don't have 600hp like in the example you gave"

That's the point, razor.  I was talking about street cars.  

A re-built T28 can be made to accept a T3 wheel.  This set-up can push 30psi.  As far as efficiently, I'll tell you when I get it back.  

You're still an ass.
