Albeit that the MR16DDT is 188HP and higher torque than the N/A MR1.8, the million dollar question is, "Where am I going to get one ?"
That engine has found its home in the Japanese Juke 1.6GT and the Chinese spec Tiida. Both are relatively new vehicles, so getting an engine from one at present time, is like finding the proverbial needle in the haystack.
At this moment the possibility of importing a used Juke so equipped, is easier than finding the turbo engine in our used parts dealerships. (Of course one would set you back close to TT230,000.)
Even if you get an engine, the cost of that unit would be astronomical, before you even pay for the install, and ironing out glitches.
In any event, the candle would cost more than the funeral. I don't know if the bragging rights is worth all that money and headache.
Then some guy with a stock PCD Subaru Legacy GT 2.0 costing $110 or less would iron you flat on the Hochoy.
With some refinements, a 122HP MR18 could add some zip to your Tiida.
