There was talk of the disco potato awhile back and I found some more information on it. ATP
has two GT28 variants,
and the GT2871R http://www.atpturbo.com/mm5/merchant...egory_Code=SUB
Garrett actually made a prototype bolt on back in the day,
I would really like to experience the transient response of this turbo as it is highly touted. But I can buy 2 16g's for the same price.
