There are some legitimate reasons for wanting to mod a N/A instead of buying a Twin Turbo. For me having the back seats are priceless, I have twin 6 year olds that love my N/A almost as much as I do. So for more power I am forced into either doing a complete TT swap or taking my N/A up a few stages. I found that taking my N/A up a few stages is fun; the key for me is to not be dumb enough to compare my N/A to a Twin Turbo…and set reasonable expectations.
