cut back blades are a kind of bodgey mod, just gives more turbine flow at the expense of response.
different compressor housings? usually only comp housing options are ported shroud or maybe for bolt on pipes rather than slip on ones.
different turbine housings are always an option tho, bigger they are the more flow but less response and higher boost threshold, smaller they are the quicker response, but may be restrictive, and more likely to surge.
and off the top of my head i can think of 3 main types of "official" GT30, plus the hashed up hybrids various companies call GT30s.
of each of the official ones you will get 3 turbine housing side options, a couple of compressor housing options, plus about 8 different turbine housing styles/fitments.
so no, just asking for a GT30 aint wise
