Restored Factory Backing for Time-Tested Toyota 4A-GE Engine

In an exciting development for car enthusiasts, Toyota Gazoo Racing has announced plans to reproduce parts for the legendary 16-valve 4A-GE engine, famously used in the Toyota Corolla AE86. This initiative is part of the Toyota GR Heritage project, aiming to preserve and celebrate Toyota's rich motorsport history.

The reproduced parts, intended to be available soon, will undergo significant improvements, thanks to modern manufacturing technology. The engine block and cylinder head will be remanufactured, with modern honing processes enhancing cylinder bore precision. The intake and exhaust ports will feature thicker walls, and the head's intake ports will receive a coating to minimize surface irregularities and inconsistencies between individual engines.

Moreover, the crank cap structure has been revised, and a more rigid cast iron is used in the engine block for improved durability. Additionally, extra bosses and ribs have been added to facilitate transverse installation for front-drive Toyota cars.

While there is no specific information available regarding the exact timing of spare parts availability for the 4A-GE engine, Toyota Gazoo Racing assures that the reproduced parts will benefit from modern manufacturing technology's improved quality and precision.
