I think the max you can reach with "all tricks" is maybe an additional 50 hp = $3 ~ $4k
After that it gets real expensive with either an engine transplant > $15k or a turbo, also > $15k, so at this point it really might be cheaper to get a different car....
You turbo or supercharge your boxster and it will blow up.... I promise you... You may get even a full year out of it, but this engines will go out on you unless you fully build them... And again, Naturally Asperated is the way to go if you want fast, useable power..
