You can put a 350 in it. That would be an NA with at least 200 hp.

sounds like you'll never make more than 160-170hp.

and if u are planning to keep it na and still get more than 200hp out of it u already are out of luck because s4 rotors are lower compression which is more suitable for boost than na.. s5 rotors with headers, exhaust, and a bridge port could yeild close to 250-300hp but that's only if u don't mind carrying ear plug when u drive
