4AGE 20V Blacktop Engine Swap Project Diary

The AE86 was available with a fuel-injected 4-cylinder twin-cam 1587 cc 4A-GEU engine in Japan and Europe which was also used in the first-generation Toyota MR2 (AW11). This engine had a maximum power output of 130 PS (97 kW) and 103 ft·lbf (140 Nm) of torque in standard form.^[1] The AE86 came with a 5-speed manual gearbox, and later came with the option of an automatic. The 4A-GE engines used in the AE86 and AW11 were equipped with T-VIS (Toyota Variable Induction System). The AE86 had an optional Limited Slip Differential (LSD).^[1]

In North America, a modified 4A-GEC engine was used to comply with California emissions regulations. Power was rated at 112 bhp (84 kW), and 100 ft·lbf (136 Nm) of torque.^[1]

The AE86 used ventilated disc brakes. The car was equipped with a MacPherson strut style independent suspension at the front and a four-link live axle with coil springs for the rear. Stabilizer bars were present at both ends.^[1]

Lower-spec American AE86 SR5 models used the 1587 cc 4A-C SOHC unit, did not have an optional LSD, and had rear drum brakes.

Models equipped with the 4A-GE engine received a 6.7" rear differential, while 3A-U, 4A-U, and 4A-C models received a smaller, weaker, 6.38" rear differential.

The AE86 SR5 (4A-C equipped) had an optional automatic transmission, though the GT-S model (with the 4A-GE DOHC engine) only came with a standard 5-speed manual gearbox.
