What's the best performance setup for the g20 that would incorporate the most amount of horsepower the least amount of noise and no NOS?

also im gonna get ground control coilovers any preference on struts/shocks that will make the car feel as smooth as the stock setup or better?

TURBO!:D :D

TURBO! :D :D

For the dampers, try Koni. Don loves his and I think Koni make the best dampers in the world. BTW, this would be better addressed in the suspension section.
