Hey Jason, I have an awesome idea... You ready? Swap in a motor... that YOU want in there... I mean, if you are set on an SR and want to do the whole car a certain way, do it... Most of the motors being suggested are great for a lot of horsepower... Not saying they wouldn't be good for drifting or whatever. If you really want to get into drifting, get the set up that is going to help you in that area the most... Either way, good luck Jason.
