I don't know anything about engines but was wondering how much extra work would be needed to use a flat plane crank to get that Ferrari type sound?

The RD Sport engine uses a larger bore and longer stroke, this engine is using a stock bore and longer stroke.

A flat plane crank would require new cams, completely new software and lots of R&D to make it work properly for a street driven car..
