AVOTurboworld has been a huge fan of the Mazda MX5 Roadster from the first NA6 Roadster released in 1989. AVO was impressed with the way they drove stock. It was even more impressive how they performed after a few modifications were made! AVO introduced the first turbocharger kit specifically for GEN 1 MX5 Roadsters (Miata), which paved the way to record-breaking performance at the track earning AVO serious recognition in the automotive industry. The all new Mazda ND Roadster featuring the SKYACTIV 1.5 and 2.0 liter motor has just been released. AVO noticed Mazda made a drastic shift by going back to their roadster roots which originally put them on the map among automotive enthusiasts.

After extensive road tests, AVO felt the new lightweight ND MX5 was impressive right out of the gate, but it does leave a lot on the table when it comes to obtaining a more exhilarating experience you would expect from a roadster. If you’re looking for the ultimate roadster experience, driving with the top down while carving your way to a rural destination is a must. But no matter how impressive the cornering capabilities are, the engine performance left us wanting much more. It lacks the “zip” feature you would expect from a small sports car. The exhaust tone was too quiet. We want to actually feel the engine working while driving in a more spirited fashion. AVO knew the potential was there waiting to be unleashed. This is what sparked a full year of design, engineering, and testing to create a complete turbocharger package.

Just like all AVO products, the goal was to create a kit that incorporates an OEM high quality fit and finish. The final product is exactly what AVO feels the enthusiast desires and deserves. The AVO Turbocharger kit was designed to work for both RHD and LHD models in all countries. Extensive tests were performed in three countries on several different models, ranging from the Japanese Mazda ND 1.5L to the American and Australian Mazda ND 2.0L. The Japanese ND spent countless hours on the track under extreme conditions. AVO has a huge advantage over any competitor with the use of a local race track. This allows AVO to test products under high heat conditions gaining insight as to how the product and vehicle will perform while pushing the limits. While testing the Australian Market Mazda ND, we spent 4 months and over 10,000 km tuning in various conditions. While testing throughout America, AVO utilised 91 octane gas ensuring the car will perform as a dependable daily driver. These tests are necessary helping give confidence to the end user. Anyone investing in the AVO product will know that it will perform and maintain its reliability no matter where you’ve located. AVO designed this turbocharger kit specifically for the Mazda ND.

AVO includes all the necessary supporting components. The turbo kit incorporates an AVO18/49 Billet water cooled turbocharger with an internal wastegate using a 5psi actuator. The turbo mounts to AVO’s impressive custom stainless steel cast exhaust manifold. The exhaust manifold is ceramic coated to keep the under bonnet temperature down and to help turbocharger spool. AVO didn’t leave anything uncovered when making this turbo kit. AVO includes all the water/oil lines and fittings making this a true direct bolt on kit. No modifications are necessary making this kit an easy install. This turbo kit has been designed to bolt up to the stock air intake box base. AVO includes their Flat Panel Air Filter and Air Box Lid to maintain the OEM look. There’s no need to worry about the fuel system.

During extensive testing AVO spent a lot of time ensuring it will work with the standard fuelling system for a complete bolt on and drive setup. One of the most sought-after features of this kit was AVO’s ability to maintain the OE look! The oversized front mount intercooler has been specifically designed to fit with the standard bumper beam without trimming or modification. When the hood is popped it would be hard even for an enthusiast eye to recognise anything that’s been modified or tweaked for additional power. We have the tuning option and it is by AVOTurboworld via its Power + Reflash Tool that simply plugs in to the OBD Port and allows you to save your standard NA stock car file. Then by following the on screen commands, this will allow you to flash your car with the AVO Stage 1 base map that is provided with the purchase of the AVO Turboworld Stage 1 kit.

So what can you expect from this kit? Our testing at 5~6 psi on 91-octane gas in the USA produced 210 whp (247 crank hp) and 210 ft/lbs of torque! While in Australia 142kw at the wheels with 275nm torque on 98 octane fuel. All this additional power tested safely on the stock fuel system! That’s a 50% power increase on pump gas, and you will see even better gains if you have access to higher octane gas. The stock motor has blistering high compression ratio at 13:1, allowing fantastic low-end response when used in conjunction with the AVO turbo kit. This high compression ratio does make gas quality even more important than ever! Turbocharging a high compression engine and maintaining reliability was a little easier due to the all new SKYACTIV motor features. An incredibly well made combustion chamber along with a direct injection fuel system allowed AVO to take tuning to another level while maintaining the reliability of a stock engine. While many people may associate it with the old motors from Mazda, there’s absolutely no comparison! The entire design of the engine was improved tremendously from anything previously made by Mazda. Mazda focused on much more than just the engine. The technology surrounding the ECU has grown light years from previous models. Cylinder knock detection and variance in the AFR (Air/Fuel Ratios) react incredibly fast. This lightning speed feedback allows the car to adjust ECU parameters better in extreme conditions.

What does this mean for you? Your car will maintain efficiency at a safe level ensuring the most power and throttle response. The new direct injection improves both power and gas mileage tremendously. AVO has managed to maintain fuel consumption same as stock, and in some cases better mpg under normal cruising speeds on the highway. Unfortunately mpg is going to be dependent on your right foot and how much fun you’re having. We know from experience! The AVO Turboworld header back exhaust system features all the new GEN 3 design aspects. Constructed out of 2.5” durable stainless steel and incorporates a high flow muffler all tucked under the rear bumper in the OEM position. The 4” polished single rolled style exhaust tip is adjustable allowing you to customise the look and feel of your exhaust system. There’s a noticeable dip in the factory torque curve. AVO combats that performance decrease by offering you a 5” high flow metal cat converter located in the down pipe. The reduced back pressure in the AVO’s exhaust system will improve performance throughout the entire rev range. The tone is improved, adding a sporty note from the rear of the vehicle. All of these added features help improve the overall performance by directly putting power to the ground where it belongs!

If you want real world driving numbers, AVO has them! In stock form, the Mazda ran from 40kmh to 80kmh in 5.9 seconds during a 3rd gear pull. After we installed the AVO turbo kit, the Mazda dropped down to 3.4 seconds! The AVO Turboworld Stage 1 will truly excite all Roadster enthusiasts with these gains! Why AVO’s Turbo kit over other Turbo kits? AVOTurboworld has been manufacturing bolt on turbo kits for over 30 years. Our goal has always been to manufacture the turbo kit with the same look and feel you would expect out of a high quality OEM part. This saves you money during installation and having to source or modify custom components when adding a turbo kit to your NA model.

AVO is the manufacturer of these kits. We can support the product and our customers who invest in AVO’s turbo kits. If you ever run into an issue due to wear and tear or damaged product, AVO can get you the correct part you’re trying to source. Because AVO has such a strong background in R&D and testing, we found a straight 4 cylinder manifold is susceptible to cracking over time. The factory tubular design has proven to fail prematurely. AVO manufactured a Cast Stainless Steel Manifold giving our customers a product they can depend on. Our intercooler tanks are made from cast aluminium to get the best flow and reliability. All our intercoolers are pressure tested from the factory and powder coated to make sure the product is protected from any debris or grime from daily road driving. The AVO Turbocharger suits many performance options. It works amazingly well for low boost applications running the 5psi actuator on pump gas. It also has enough headroom for customers who’ve gone beyond stock engine components running 15psi on a 2.0L engine equipped to handle E85 fuel producing 400 whp.

Under normal conditions this kit can be installed in 7-8 hours from start to finish. This job is much easier to perform using a lift and proper tools. One of the hardest portions of this install is removing the stock header. You’re required to remove the engine mounts which will make installing the turbo kit much easier. Any installation shop will need the ability to weld the turbocharger oil drain fitting. You also have the option to purchase the pre-welded oil pan from AVO. The only modification to any OEM part is to the plastic under tray beneath the engine. It needs two 2.5” holes to be cut with a box knife or cutting tool. This will allow proper fitment of the silicone intercooler pipes. Other than that, the installation is straight forward for most independent technicians or DIY’s.
