Yea but if you do turbo you cant boost too high without doing alot of tuning and some internals which means $$$. Like that guy with the turbo Type R I saw the best of a 14 in the quarter and he has spent well over $3000 and Im right there with him and I have yet to break $1000. So yea I guess you can do more but keeping it N/A its a great car. By jdm I mean header maybe higher comp. pistons etc...
