The 2.0L ABA engine is a popular choice for turbocharging, offering a balance of performance and reliability. This article explores the feasibility of a daily driven ABA 2.0 turbo setup, addressing common questions regarding reliability, power output, and key components.
Building a Reliable Daily Driven ABA 2.0 Turbo
One of the primary concerns when turbocharging a daily driver is reliability. With the ABA 2.0, a properly built and tuned turbo system can provide substantial power gains without sacrificing daily drivability. A key factor is managing boost levels. Running lower boost, around 8 psi, on premium pump gas can maintain reliability for daily use.
Turbocharger Selection and Power Output
The choice of turbocharger significantly impacts power output. A Garrett T3-60 trim turbo is a suitable option for the ABA 2.0, capable of producing significant horsepower. With 8 psi of boost, a well-tuned setup with this turbo can generate around 170 wheel horsepower (whp). Further power gains can be achieved with upgraded fuel management components, such as larger injectors and a tuned ECU or chip. Initial testing with a Fuel Management Unit (FMU) and smaller injectors yielded the 170 whp mark, and further tuning and component upgrades are expected to increase this figure.
Internal Components and Engine Management
For a reliable daily driven setup at moderate boost levels, stock internal components, including pistons, can often suffice, even with higher mileage engines. However, upgrading connecting rods is often recommended for added safety and reliability at higher boost levels. An Autotech 260 camshaft provides a good balance of performance and street drivability, enhancing power throughout the RPM range.
Utilizing the factory OBD2 system with a performance chip, like a C2 Motorsports chip, paired with larger 42 lb/hr injectors, allows for precise fuel delivery and ignition timing control. This setup offers a more reliable and tunable solution compared to using an FMU. Upgrading the fuel pump, such as with a Walbro inline pump, is crucial for supplying sufficient fuel at higher boost pressures. While the stock fuel pump may handle up to 16 psi, an upgraded pump ensures adequate fuel delivery and prevents lean conditions that can damage the engine.
Conclusion: Achieving a Powerful and Reliable ABA 2.0 Turbo
Building a reliable and powerful daily driven ABA 2.0 turbo setup requires careful consideration of boost levels, turbocharger selection, fuel management, and supporting modifications. By focusing on these key areas, enthusiasts can enjoy a significant increase in performance without sacrificing the practicality of daily driving. Conservative boost levels, appropriate fuel and engine management upgrades, and careful component choices are crucial for achieving a balance between power and longevity.
