Ideas to boost power?

One of my relatives just bought a 2001 Turbo beetle, and was wondering what would be the best way to upgrade the turbo or just give it more power. Any ideas?

Get morso 40 spark plug wires if they have them.

Get a k4 turbo, or you can ad more power by chipping it.
I have a turbo beatle as well; I chipped it and it is a t 200 hp andi am getting a k4 turbo added to it. i can't wait to kick some ass with it
