Sorry dont get it ?? Yes its great to be different but at least be different and get something out of it. You are going to go to all that cost and effort and end up with something thats less powerful than when you started
The idea of engine swaps IMO is to get and easy jump in power without tuning the nuts off the standard lump, hence RB, JZ and V8s being the norm. To take one turbo 4 pot out and stick another in seems bizarre unless you are getting a much more tunable engine. You might as well chuck a Cossie lump in there
