Another Tuning Thread!

I've probably read about every thread on tuning the MG ZS 120 on the internet in the last month but what are your suggested cheap mods?



At present I have K+N panel filter which I hope to use in conjunction with a 52mm throttle body I am about to buy. My cat is f**** and I think creating a slight blockage which defeats the object slightly and that will be replaced next month.



Any cheap performance mods suggested? Is it worth me putting on a VVC head or will I get hassle? Although in the motor trade I am a google mechanic i.e not brilliant but I have changed a head before. I don't want to fit the head and come across issues like oil starvation etc
