Sequential Vapour Injection (SVI) for petrol powered vehicles offers unmatched reliability and performance. It provides improvements in safety and is more cost effective than conventional systems. In brief, the main difference is that SVI has an injector for each cylinder that delivers gas close to the inlet valve and has a computer that monitors the engine and individually controls each injector.

Advantages of SVI compared to conventional LP Gas systems

• Improved fuel economy
• More power
• Better cold running – the engine will automatically change over to gas when the engine warms up
• All-in-one push button LP Gas gauge. One button to change from petrol to gas and back
• Drives gas valves and petrol injectors directly so there are no separate relays
• No damaging engine backfires – gas is injected very close to each inlet valve, which reduces gas volume in inlet manifold to virtually eliminate backfires
• Safer as the gas is automatically shut-off if engine stalls
• Automatic change back to petrol operation when gas runs out, alarming to let you know it has changed back to petrol.

The installation leaves your current on-board diagnostic equipment untouched.

We are able to fit SVI systems to many vehicles. However, vehicles manufactured since December 2003 must be fitted with an emissions compliant kit. Click here for a vehicle listing of kits available.

Frequently Asked Questions:

Will I still lose performance with SVI?
No, when you convert your vehicle with the SVI kit your vehicle’s performance will remain virtually the same.

Can the SVI kit be installed on any vehicle?
Most EFI Vehicles and all Sequential Injected Petrol systems can have the SVI kit installed on them.

Will the SVI kit cost more than the standard kit?
Converting your vehicle with the SVI kit is more expensive than a conventional kit as it takes longer to install and the components are more expensive. However, the benefits of SVI generally outweigh the increased cost.
