From Initial D to Hot Version, the legendary Toyota AE86 is a staple for many tuners and racers, and equally deserving of admiration among enthusiasts is what powers it: the iconic Toyota 4A-GE engine. It’s a lightweight, reliable, and high-revving engine that boasts a sharp throttle response and smooth power delivery that demands you to rev it all the way out to redline if you want to get the most out of it. Mechanically, then, it’s a bit different from the Boxer engine you’ll find in the new Toyota GR86.
