It may be the only way for Misubishi dealers to apply warranty to the replacement parts. Otherwise, the warranty would likely be void.
Good luck with that.
Just to make it clear roller cam is misnomer, there're no rollers on camshaft. Rollers are on cam followers, tappers.
Because rollers offer less resistance cam can use more aggressive profiles. That would require stiffer springs.
One would also wonder if roller taps are the same height, are the same valves used and if valve seats were changed to resist additional force
MIVEC already addresses what is effectively 'cam profile'.
If you have any proof that Mitsubishi modified the cam profile for this engine, I would like to see it. Otherwise it's just wishful thinking - also known as dreaming, or making stuff up.
I found all the speculation surrounding the announcement of the 2017 Mirage amusing. People were absolutely *running* with what they thought Mitsubishi ought to improve on the car, and made it their reality. As if.
EDIT: I think EVO used rollers question is if they are interchangeable with ones from 3A92.

View my fuel log 2015 Mirage DE 1.2 manual: 46.4 mpg (US) ... 19.7 km/L ... 5.1 L/100 km ... 55.7 mpg (Imp)
Modify the engine and nullify the warranty. I would choose the warranty coverage, unless the two can both be had.
Again, good luck.
