the stock TD05 turbine wheel needs to be "clipped" or "cut back" to allow it to flow better once mated with the 20G or a Garrett wheel..or else..it'll start choking out.
why DSM fella's prefer the TD06 turbine wheel..mainly due to size and if you go for the Td06L2 (newer design) , less number of blades and spread out further, hence you don't need to cutback these turbine wheels.
