Welcome - the SC have been out for several years and there are many on here who have them - please use the search feature to find the many threads about it. There is no safer way to add a noticeable amount of HP to this engine and there is no other kit than the Alpine. There is at least on SCed on in Arizona and the install is easy - any shop can do it in about a day or most driveway mechanics can do it in a weekend - download instructions on my page. It is the best mod I have done and enjoy EVERY time I drive.
