I'm looking at the turbine side options for the SC61 turbo and it comes in 3 sizes T350-52 (630HP), T04-69 (650HP), T04-76 P-Trim (680HP). Are these the same as the stage 3, 5 and P trim I see people reffer to as? My goal is 600AWHP on a built 2.4 and I have all the supporting mods to do it.(see bellow) Spool isn't an issue but I don't want to overkill it if I don't have to. These options are all in a .63 T31 5 bolt housing as that's the only option from PTE, ported T04S compressor cover for less surge...although I'm not sure if the 2.4 would surge as badly as the 2.0 with this GT40 compressor wheel.
Does anyone have any first hand experience with the different size turbine wheels? I'm more interested in how laggy the P trim is and if its even worth going to it considering the housing is only .63 A/R...could a stage 5 or even a stage 3 wheel net results within a 30-50HP range? I've made some decent power on my .48A/R stage 3 60 trim going 11.0 on my 2.0L with a 1.8 60' but this 2.4 seems to be a different beast and likes to breath tremendously in the upper RPMs making the small 60 trim obsolete at only 24psi. Any input is appreciated
