I'm feeling the need for some more power, and i've heard many good and bad things about forced induction. What kind of gains could i potentially see from adding a supercharger or a (or multiple) turbochargers? (assuming perhaps a 7-9 boost) Also, what kind of reliability issues could i run into? it's my daily driver, so i kinda need it to work reliably. As it stands, the car itself has only had one reason to go to the shop, outside of maintinance, and that was to replace the water pump at 120k. Also, i have done most of the small stuff, like changing the air filter, changing chips, aftermarket exhaust, so aside form completely changing out the top half of the engine, (and therefore essentially making it into an M-engine) i'm not quite sure what else there is to do to get some more power. Thanks.
