Engine tunings options suggestions

Hi!
I got a couple of suggestions. nothing radical changes, more like fine tuning
To have the option of twin and single entry turbo in the turbo section.
Valve size and valve springs tunings options.
Oilcooler, different types like air or water cooled and sizes.
ability to change gear ratios on the gearbox, gear to gear.
E85 as fuel option
I keep fill up when I get more idees and hope i get feedback what works and dont and hope you like my idees
