4a kodlu motorlar 80 yılında çıktı.
The 4A was produced from 1980 through 1998. All 4A engines have a displacement of 1.6 L (1,587 cc). The cylinder bore was enlarged from the previous 3A engines at 81 mm, but the stroke remained the same as the 3A at 77 mm, giving it an over-square bore/stroke ratio which favours high engine speeds.
Numerous variations of the 4A design were produced, from basic SOHC 8-valve all the way to DOHC 20-valve versions. The power output also varied greatly between versions, from 70 hp (52 kW) at 4,800 rpm in the basic California-spec 4A-C to 170 PS (125 kW) at 6,400 rpm in the supercharged 4A-GZE.
