well I dunno if I'm just a skeptical type guy but I figure if a mere $3K could get you 50HP then allot of people would be doing this. The crazy thing is that 50HP doesn't really feel like 50HP...feels more like 30. I think your mods will be below 30HP. And with header and exhaust upgrades you won't really feel the new ponies until you are moving. The car will be nearly the same when launching from a standing start.

Personally I'd sooner spend the muney on coilovers or lighter wheels or premo rubber. If you want more power, take a hard look at getting into a 2000 S.
Might require $5K instead of $3K but you'll get what you want in the end.
