this is the turbo i run on my busa, off a typhoon or cyclone. these guys are good and i have read there is a 9 blade wheel that is supposed to spool faster but never tried and am not going to because i am changing power plants anyway. now the 1 thing i have found about this turbo is that the exh housing is ported larger to let the exh out faster than the other td06 turbine housings, which i considered to be a plus for the rail app but am no expert. it does need to spool faster and i think this wheel would do that.
