I'm trying to figure out a way to get the most power out of the R35 while still keeping it somewhat street legal.

We're allowed to add 20% power .. let's make that 430 kW. Would it be possible to upgrade the exhaust, turbo, intake, etc. to achieve that and add the COBB access port for another 50+ HP while retaining the option to switch back to the legal 430 kW or less in economy mode?

I basically intend to use it as a daily driver but still like some extra power for the track days.

Might that work or is there something to it that I don't quite see yet?
