I wouldnt change the turbo size for anything. I love it, I think its a perfect stock motor turbo. If you want to go bigger, we will have an option. We wanted a turbo that will spool crazy fast and make about as much as a stock motor will hold. There were long thought processes into choosing this turbo.
We will have the bigger turbo option available really soon. You can always make more power with a bigger turbo, but you will always be faster with a properly sized turbo on the street.
