NA s5 mod question

I was just wondering what other power mods can you do to a s5 NA besides intake,downpie presilencer, and catback exhaust, thanks alot guys

CAI, Larger diameter intake piping, ported TB, throttle plate work, porting of the actual motor, proper fuel tunening, header, full exhaust, standalone engine management.
Or go with dual downdraft carbs.

But you would also want to look at the drivetrain. Things like the flywheel can make a huge difference. Pulleys, lightweight driveshaft, diff, half shafts, tires, wheels, suspension.

All those things can be combined to make the car quicker. Keep in mind a NA car with stock porting is somewhat limited in power, but thats not to say you cant get some decent power out of one.

maybe TB mod, but you have to do it right
