Who cares what they've achieved with a bolt on. People are getting insane numbers by other turbos that put out way more higher whp on the stock block. Who cares if its a bolt on or internally wastegated.....you don't get a 3 second head start on the track for doing that. LOL Check out NASIOC and see the numbers people are getting with the GT30r and GT35r on the stock block.
