2017 Toyota GT86: A Closer Look at the FA20D / 4U-GSE Powerplant

The heart of the 2017 Toyota GT86 (and the 2013-2016 Scion FR-S, and the 2013-2020 Subaru BRZ) is the FA20D engine, also known by Toyota code 4U-GSE. A 2.0-liter flat-four boxer configuration renowned for its performance and balanced design, this naturally aspirated engine delivers a thrilling driving experience with responsive throttle, perfectly linear power delivery, and a high-revving character that rewards committed driving. Its lightweight flat layout contributes to the GT86 / FR-S / BRZ balanced handling, low center of gravity, and approximately 53/47 weight distribution, making it a favorite among driving enthusiasts who value chassis feel and predictable handling over raw straight-line speed.

The FA20D NA design philosophy is fundamentally different from turbocharged competitors: no turbo lag, perfectly linear throttle response, a powerband that builds progressively from 4,000 RPM to the 7,400 RPM redline, and the famous flat-four engine note that connects driver to machine. The engine 2017 minor power bump (from 197 HP in pre-facelift Scion FR-S applications to 200 HP in the 2017+ facelift Toyota GT86 and BRZ) came via revised intake tuning and cam profiles.

Important: Same Engine Across All Three Triplet Cars

The FA20D / 4U-GSE engine is the SAME ENGINE used in three different vehicles:

• Toyota 86 / GT86 (US-market 2017 to 2020 model years), called “Toyota 86” or “GT86” depending on market
• Scion FR-S (US-market 2013 to 2016), before Toyota retired the Scion brand and renamed the car to Toyota 86 / GT86 for 2017+
• Subaru BRZ (US-market 2013 to 2020), Subaru badge-engineered version of the same vehicle

All three cars share the same engine block, same internals, same cylinder heads, same D-4S injection system, same ECU calibration philosophy, same 200 HP / 151 lb-ft specifications (post-facelift), and same 7,400 RPM redline. The engine in our inventory will fit any of the three triplet cars without modification (with appropriate attention to the specific vehicle wiring harness and accessory layout). If you are looking for a Subaru BRZ engine or Scion FR-S engine, this Toyota GT86 FA20D listing is exactly what you need.

JDM Performance Engine Context

The FA20D / 4U-GSE (this listing) is the Subaru-Toyota collaboration flat-four boxer NA engine. For buyers comparing JDM-philosophy performance engines across configurations: the FA20D (this listing, 2.0L NA flat-four boxer with D-4S dual injection, 12.5:1 compression, 200 HP / 151 lb-ft, 7,400 RPM redline, used identically in Toyota GT86 / Scion FR-S / Subaru BRZ triplet cars) is the lightweight low-CG horizontally-opposed sports coupe engine; the Nissan KA24DE (our vaz164 listing, 2.4L DOHC Inline-4 NA with cast iron block, 155 HP / 160 lb-ft, used in 240SX S13 / S14 / Altima / Frontier) is the rear-wheel-drive drift / JDM swap Inline-4 base; the Honda F20C / F22C1 (our vaz144 listing, 2.0L or 2.2L NA Inline-4 with 9,000 RPM redline and forged internals, S2000 only) is the high-rev specialty NA Inline-4 with the highest specific output of its era; the Honda K20Z3 (our vaz115 listing, 2.0L i-VTEC Inline-4 with 8,000 RPM redline, Civic Si engine) is the mainstream K-series Honda performance Inline-4; the Toyota 2JZ (our vaz112 listing, 3.0L cast iron closed-deck Inline-6 with forced induction capability) is the JDM Inline-6 forced-induction-capable alternative. Four distinct NA philosophies plus the 2JZ forced-induction option: FA20D for low-CG boxer sports coupe handling; KA24DE for RWD drift / swap accessibility; F20C / F22C1 for purpose-built high-rev sports car; K20Z3 for broad Honda performance; 2JZ for high-HP forced-induction targets.

Features of the Toyota GT86 / FR-S / BRZ FA20D Engine

• Flat-Four Boxer Configuration: The horizontally-opposed cylinder layout provides a low center of gravity (the engine sits lower in the bay than inline or V engines), excellent primary balance (no balance shaft required), and the distinctive boxer engine character.
• Performance: 200 HP at 7,000 RPM, 151 lb-ft at 6,400 RPM (post-facelift specifications). The power builds progressively from 4,000 RPM toward redline.
• D-4S Dual Injection: A standout feature is Toyota D-4S injection system, which combines direct fuel injection (high-pressure injectors firing directly into the combustion chamber for cooler intake charge and higher compression tolerance) and port fuel injection (low-pressure injectors firing into the intake runners for cleaner idle and avoiding the intake valve carbon buildup that affects pure-DI engines). This dual injection system optimizes fuel delivery across the entire RPM range, enhancing both performance and fuel efficiency while preserving long-term reliability.
• High Redline (7,400 RPM): The FA20D redline is among the highest in modern non-exotic gasoline engines.
• Square Bore and Stroke (86mm x 86mm): The perfectly square geometry (bore exactly equal to stroke) is a classic engineering choice balancing low-end torque with high-RPM peak power. The “86” name in “Toyota 86” / “GT86” pays homage to this geometry and to the legendary AE86 Corolla.
• High Compression (12.5:1): Very high compression ratio for an NA gasoline engine, contributing to thermal efficiency and power output. Requires premium 91+ octane fuel for full output.
• Dual VVT: Variable Valve Timing on both intake and exhaust camshafts of both cylinder banks (4 VVT actuators total) optimizes valve timing across the entire RPM range.
• DOHC 16-Valve Heads: Dual overhead camshafts per bank with 4 valves per cylinder provide excellent breathing characteristics.
• Emissions and Efficiency: Meets stringent emissions standards while delivering respectable fuel economy for a sports car: EPA estimated 21 mpg city / 28 mpg highway (manual transmission), with LEV II emission rating.

Engine Options and Configurations

• Long Block Assemblies: Include the complete engine block, cylinder heads (both banks), camshafts, valvetrain, and all internal components. This option is ideal for a straightforward engine swap with minimal additional parts required.
• Short Block Assemblies: For those looking to reuse their existing cylinder heads, upgrade to performance heads, or build a forced-induction setup. Includes the engine block, crankshaft, connecting rods, pistons, and internal components up to the cylinder head gasket.

Performance and Upgrades

The 2017 Toyota GT86 / FR-S / BRZ FA20D engine responds well to various upgrades:

• High-flow intake systems (cold air intakes, drop-in filter replacements)
• Performance exhaust systems (cat-back exhaust, headers, equal-length unequal-length manifolds)
• ECU tuning (Cobb AccessPort is the most popular tuning solution)
• Forced induction (Edelbrock supercharger kits, HKS supercharger kits, turbocharger kits). The FA20D lower stock output combined with the boxer block strong bottom end makes forced induction a popular path to 300+ wheel HP

Known FA20D Considerations

• Oil Consumption: The FA20D is known for some oil consumption, particularly during high-RPM driving. Toyota / Subaru consider this normal up to a certain rate; we document oil consumption baseline before sale.
• D-4S Direct Injection Carbon Buildup: Despite the port injection portion of D-4S helping reduce intake valve carbon buildup, some high-mileage FA20D engines benefit from intake valve carbon cleaning service.
• Timing Chain: The FA20D uses a timing chain (not belt), which is generally low-maintenance but can develop stretch at very high mileage.
• Valve Spring Recall: Some 2012-2013 production FA20D engines were subject to a valve spring recall (subject to specific VIN range); we verify any applicable recall completion before sale.
