Was this on a Evo ??? VIII or IX ???
I would love to see some real hard data on the 40R on the Evo but really have not seen anything very solid. Especially coming from either of the big 2 AMS or Buschur. If I find hard facts from either one of those two shops then I would consider it as fact , hahaha.
I know I will have the motor to handle whatever I want to throw at it. But dont want to waste cash on an unproven turbo setup!!!
