For 2022 the Toyota GR86 and Subaru BR-Z was given a larger evolution of the venerable horizontally opposed “Boxer” naturally aspirated four-cylinder engine. Now with a larger bore of 94 mm up from 86 mm, the engine now displaces 2387cc.
This brings output up from the old 2.0-liter engine, now 228 horsepower from 205. Torque increases too from 156 to a maximum of 184 pound-feet when matched to the manual transmission. Best of all the torque peak comes on lower in the rpm range at 3,700 rpm instead of 6,600 rpm as before.
Its additional power comes from not only the increase in displacement but a significantly revised intake and exhaust tract and improvements to the Toyota D-4S dual injection system which employs both port and direct fuel injection.
The direct-injection system provides a cooling effect in the cylinders, which allows the engine to use a high 12.5:1 compression ratio for maximum power. Port fuel injection comes into play during light to medium loads for more efficiency.
The larger and more powerful engine brings better 0-60 times of 6.1 seconds for the manual transmission, down from 7.0. The automatic sees a much quicker 6.6 second 0-60 down from 7.9 seconds.
Maintenance is straight forward with all of the major fluids and service points easily found and accessible.
The 12-volt battery is located at the passenger side firewall. The ECU can be found just ahead of it between the engine and the strut tower. The main fuse box is at the front passenger side of the engine compartment, easily accessed by popping a couple clips. A handy fuse removal tool is included inside.
Checking and filling the engine coolant is done at the passenger side front of the engine compartment just to the left of the radiator at the white plastic tank with a yellow cap. The yellow handled dipstick to check the oil is easily seen at the passenger side front of the engine.
Just to the right of the dipstick on the driver side of the engine is the oil filter mounted on top of the engine for easy access as well as the oil filler cap. Moving ahead to the right you will find the windshield washer fluid reservoir with a yellow cap. The large air filter box can be found at the front of the engine compartment easily accessed to check and change the filter by popping a few clips.
Checking the brake fluid is done at the usual location at the driver side firewall at the reservoir mounted atop a conventional brake cylinder and vacuum power booster setup.
Other items of note around the engine compartment are the beefy strut tower braces that span the compartment between them and the firewall for strength and torsional rigidity. Because of the engine’s forward locations you can easily see the transmission looking down behind it.
Looking down in front of the engine you can see an artfully routed single serpentine belt for all of the accessory components. The ABS control unit can be found at the driver side front of the engine compartment just ahead of the strut tower.
