The Proton Persona, a top-seller from Malaysia's homegrown brand, currently comes packing a 1.6L naturally aspirated engine paired with a 4-speed automatic transmission. This powerplant features DOHC (Dual Overhead Camshaft) technology and a VVT (Variable Valve Timing) system, churning out 107 horsepower and 150 Nm of peak torque – a solid all-rounder for daily city commutes with balanced fuel efficiency.
If owners start asking about engine modification possibilities, it's crucial to highlight that the factory setup is already optimized for the car's body structure and local emission regulations. Any engine upgrades need to comply with JPJ certification standards. For instance, swapping in the brand's own 1.5L TGDI turbo engine (like the one in the Proton X50) would require a professional tuning shop to adjust the ECU and ensure proper driveline matching, followed by the mandatory PUSPAKOM inspection.
It's worth emphasizing that engine modifications can void your warranty and necessitate changes to your insurance policy. For a more balanced approach that prioritizes legality and reliability, we'd recommend exploring Proton R3's line of performance parts, such as their intake and exhaust upgrades.
Additionally, Malaysia's hot climate demands extra attention to engine cooling, so upgrading the cooling system should be a consideration if you're modifying. For long-term engine health, regular oil changes using API SP certified 5W-30 fully synthetic oil are a must to protect those internal components.
