Stock. Engine is most likely going to stay that way since I live in California and almost every mod that can be done to this car will cause me to fail smog here. However...the plan is to eventually upgrade the suspension and handling bits to help me get better times when I go autocrossing .
I would only do it if/when the Type R becomes a production model. Otherwise, I'm loving my current car. And as far as feasibility...that is a discussion I'll have when the time is right with my lovely wife
