Toyota reinstates original equipment manufacturer (OEM) backing for the iconic 4A-GE engine model
The Toyota Gazoo Racing team has announced a significant update to the iconic 4A-GE engine, a staple of the Toyota Corolla AE86. This four-cylinder engine, known for its popularity and fame, is now set to become even more suitable for engine swaps, thanks to modifications for front-drive applications.
Under the Toyota GR Heritage project, the official parts program for the 16-valve 4A-GE engine is being coordinated. The remanufactured parts will benefit from the improved quality and precision offered by modern manufacturing technology.
One of the key changes is the thicker walls for both the intake and exhaust ports. Additionally, the block will be made from a more rigid cast iron, and a revised crank cap structure will be implemented. These modifications aim to enhance the engine's durability and performance.
To facilitate engine transverse installation for front-drive applications, additional bosses and ribs have been added. Furthermore, the head's intake ports will receive a coating to reduce surface irregularities, and modern honing processes will enhance cylinder bore precision.
The coating on the head's intake ports is intended to reduce differences between individual engines, ensuring a smoother and more consistent performance. This attention to detail underscores Toyota Gazoo Racing's commitment to producing high-quality parts for the 4A-GE engine.
The aftermarket scene in Japan has played a crucial role in keeping the Toyota Corolla AE86 an enthusiast favourite for decades. With the remanufactured 4A-GE engine, Toyota Gazoo Racing is further catering to this community, ensuring that the legacy of this legendary engine continues.
