i have an '04 s2 and it's been suggested to me that i turbo the engine vs. the much more common supercharger. the compression is high (11.1:1) but i could up that some. sleaving the block is a must for either and i plan on new internals. so that brings me to the question, boed or charged? any s2 owners that are not n/a? what has fried in your engine? thanks for feedback!
