The direct answer: you can, but there are two main paths. You can buy a factory-turbo Civic (EX, EX-L, Touring, or the performance-oriented Si) that already comes with a turbo, or you can attempt an aftermarket turbo retrofit on a non-turbo 2017 Civic. The aftermarket route is complex, costly, and carries risks to reliability, warranty, and emissions compliance.
Factory turbo options
Honda offered a 1.5-liter turbo engine in most non-Si 2017 Civics, along with a distinct high-performance Si variant that also uses a turbo but is tuned for peak output. Here’s the gist of how it breaks down in the 2017 lineup:
- Civic EX, EX-L, and Touring — 1.5L turbocharged engine producing about 174 hp and 162 lb-ft of torque; typically paired with a CVT in most markets (the Si uses a manual transmission).
- Civic Si — 1.5L turbocharged engine tuned for around 205 hp, designed for sporty performance; typically paired with a 6-speed manual transmission.
In short, a factory turbo option is already available in several 2017 Civic trims, and the Si represents the top-end, performance-focused use of the same turbo architecture.
Aftermarket turbo retrofit: feasibility and considerations
If you own a non-turbo 2017 Civic (the base 2.0L engine), adding a turbo is technically possible but involves substantial work, cost, and risk. A successful install usually requires more than just bolting on a turbo; it demands supporting upgrades and professional execution.
- Engine strength and internals — boosting a naturally aspirated 2.0L engine can stress pistons, rods, and bearings; some builds use lower boost or require internal upgrades.
- Fuel and ignition — upgraded fuel injectors, fuel pump, and an ECU/tuner are essential to prevent detonation and lean conditions.
- Forced induction plumbing — turbocharger, intercooler, piping, exhaust, and robust cooling need proper integration and heat management.
- Cooling and lubrication — upgraded radiator/oil cooler may be needed to handle extra heat and sustained boost.
- Transmission and drivetrain — increased torque may necessitate clutch upgrades or drivetrain reinforcement; automatics may have limited tolerance for long-term boosted use.
- Tuning and safety — a reputable tuner and a dyno session are typically required to achieve safe, reliable power levels.
- Cost and timeline — a full aftermarket turbo install can run from several thousand to well over ten thousand dollars, plus potential maintenance considerations.
Warranty, emissions, and legality are key considerations. Aftermarket turbo setups usually void the manufacturer’s warranty and may run afoul of local emissions laws unless the kit is certified and installed correctly in your region. If your goal is a turbo feel or extra power, buying a factory turbo-equipped model or the Si is often the safer, more predictable route.
Warranty and legality
Adding aftermarket turbo hardware generally voids the vehicle’s warranty and can impact emissions compliance. In many places, you may need a certified system and proper inspections to stay compliant with local laws and regulations.
Cost, logistics, and timing
Expect a project that requires skilled labor, a significant budget, and several weeks to complete. Plan around your target power, usage needs, and how long you’re willing to live with potential maintenance and regulatory considerations.
Summary
The 2017 Honda Civic offers two practical routes to turbo power: (1) buy a factory turbo model (EX, EX-L, Touring) or the high-performance Si, which provides reliable, dealer-supported turbo performance; or (2) pursue an aftermarket turbo kit on a non-turbo model, which is possible but complex, expensive, and carries warranty, reliability, and emissions considerations. For most buyers seeking a straightforward turbo experience, starting with a factory-turbo Civic or the Si is the safer, more predictable option.
