V6 - V8 CONVERSIONS Thinking of Upgrading from a V6 to a V8? Here’s what you need to know. We get asked about V6 to V8 conversions all the time — so we’ve put together some quick answers to our most frequently asked questions to help you decide if it's the right move for you. Get in Touch WHAT OUR CONVERSIONS COVER Complete V6 to V8 Conversion Package — Supplied & Fitted This is a full conversion package designed to have your car running just like a factory V8. We supply and fit everything needed to ensure the vehicle runs exactly as it should — no shortcuts. Our conversion includes: ✅ Engine ✅ Transmission ✅ All wiring ✅ Full programming and integration We source all components from complete donor vehicles purchased at auctions across Australia. Every donor car is fully running and tested before any parts are removed, ensuring quality and reliability in every conversion. OPTIONAL EXTRAS While our basic conversion package includes everything required to have your vehicle running as a V8, there are a number of optional extras available to enhance performance, drivability, and reliability. Here’s what we offer — and why you might want to consider them: Differential Swaps We stock a wide range of Commodore diff ratios, including LSD and non-LSD options. Upgrading your diff can improve traction and performance, especially if you’re increasing power output. Big Brake Upgrades Your factory brakes will handle the conversion just fine — but if you’re planning further upgrades (like one of our cam packages), we recommend stepping up your braking power. Options range from upgraded pads and rotors to a full HSV brake setup, supplied and fitted. Heavy-Duty Clutches Again, not essential for a basic conversion, but highly recommended if you're adding more power down the line. A heavy-duty clutch will handle the extra torque and extend the life of your drivetrain. Engine-Back Exhaust Systems To help your new V8 breathe better, we recommend upgrading the exhaust. We can supply and fit brand new or good-condition second-hand systems, depending on your preference and budget. OTR (Over-the-Radiator Intakes) Improving airflow is always a smart move — especially if you’re planning a cam and tune package. We offer both new and used OTR systems to suit your setup. These upgrades are completely optional but are commonly chosen by customers looking to get the most out of their V8 conversion. Have questions or want to customise your package? Get in touch — we’re happy to help.
