As far as I know there never was a 1.6 ZR, but the standard upgrades would be induction kit and sports exhaust. If you want to really go for it then cams etc but bear in mind if you factored in the cost of induction kit, exhaust and cams you could probably get a reasonable mileage 1.8 K series from a breaker. That would give you more bhp and torque than all of those upgrades.
