I think that once you go big turbo on either one, and get a nice set of cams for the evo VIII, I think they perform the same. This is just based on my knowledge, and from my experiences. What do you guys think?
03-04 Evo's have the 9.8cm Hotside. '05 Evos have the 10.5cm hotside. '06 Evos have the 10.5cm hotside with the larger compressor housing.
