Originally unveiled in 2009 as a joint development of two Japanese companies, the Subaru FA20D 2.0-liter gasoline engine entered production in 2012. This motor is installed on a sports model called the Toyota GT86 or Subaru BRZ.
Since 2012, the company has been producing the 2.0-liter Subaru FA20F or FA20DIT turbo engine, which is fitted to charged versions of the company’s popular models, including the Forester XT and Impreza WRX. This power unit has a 250–300 horsepower capacity and can be modified in numerous ways.
FA20, FA24F, and FA24D are members of the FA family.
The FA20D was set up on:
- Subaru BRZ 1 (ZC) in 2012 – 2021;
- Toyota GT86 1 (ZN6) in 2012 – 2021 (as 4U-GSE);
- Scion FR-S 1 (ZN6) in 2012 – 2016 (as 4U-GSE).
The FA20F/FA20DIT was installed on:
- Subaru Forester 4 (SJ) in 2013 – 2018;
- Subaru Legacy 5 (BM) in 2012 – 2014;
- Subaru Legacy 6 (BN) in 2014 – 2019;

Disadvantages of the FA20 engine
These devices were initially trembling at low speeds, but the firmware fixed everything;
Then, complaints about faulty gears, sensors, and bearings surfaced.
Additionally, this engine is very sensitive to lubricant and fuel quality;
Here, dual AVCS phase regulators rapidly fail due to non-original oil;
Keep an eye on the system’s lubrication level because the liners rotate frequently.
