 My main concern with using an aftermarket turbo is the oil return. The stock TG uses gravity, but I'd expect an aftermarket installation to be mounted a little low for this, requiring a scavenge pump......   yet more weight & complexity 

 
  A turbo you may look into is an Airdyne, it has its own oiling and doesn't require oil from the engine.
 I use these on snowmobiles as they have no oil.
 Another advantage of these is that in the event of a turbo bearing or seal failure it would not drain your crank case.
