Hey Darren, it's not a bolt on affair due to the flange type of the Trust turbo's, but no different than fitting up a HKS 3037 etc in that it will require a new Ex. gate manifold with a flange to suit the Trust type, as well as obviously the ex. gate itself, dump, lines etc.
They are marginally more difficult to fit as there are not heaps of manifolds that can be bought off the shelf from China to suit, so it takes away a lot of the crowd not willing to spend the cash. Ideally someone would get a custom steam pipe manifold, or one available off the shelf from 6Boost/Powertune etc and the flange can be added at the time of construction.
