HKS 23011-AT011 Short Block G16E 1.75l LC Step 3 Closed-Deck for TOYOTA GR Yaris (GXPA16) / GR Corolla (GZEA14)

Description HKS 23011-AT011 Short Block G16E 1.75l LC Step 3 Closed-Deck for TOYOTA GR Yaris (GXPA16) / GR Corolla (GZEA14)

The short block is equipped with the BCD Piston Full Kit G16E 1.75L LOW-COMP STEP3.

The block is processed to a closed deck to suppress cylinder deformation and handle high combustion pressure. Although the flow of cooling water changes when the deck is closed, the water jackets have been optimized.

The deck surface has been ground to improve flatness, and boring has been performed to improve cylinder cylindricity. After processing, the main gallery is thoroughly cleaned to reduce the risk of trouble.

Note: Stock balance shafts cannot be used with this setup.

Recommendation: HKS Racing Pro 10W50 engine oil is recommended.

• A cooling water jacket is added to the No. 2 cylinder, assuming use of the Grommet Head Gasket SUPER COOLING Pro.
• The pistons feature a BCD (bridge construction) design, achieving lightweight performance and high rigidity.
• The machined I-Beam STEP3 connecting rod is 25% stronger than the original, improving allowable torque.
• The chrome steel crankshaft has reduced inertia weight through efficient counterweight positioning and reduced pin weight.
