JE Pistons 361285 77.00mm Dish Piston Kit for Hyundai 1.6L Gamma GDI (Turb

Vehicle Fitment

• 2013+ Hyundai 1.6 L Gamma GDI Turbo (77.00 mm bore, G4GJ / Gamma-turbo family)

Features

• Forged from 2618 alloy for high tensile strength - suitable for boosted or high-stress use
• "FSR" (Forged Side Relief) design - reduced skirt width and shorter wrist pin to lower reciprocating mass and friction
• Dish-style piston crown with -8.2 cc volume - optimized for proper compression and boost compatibility
• Includes premium ring set, wrist pins and circlips - complete kit ready for installation
• CNC-machined and deburred crown & skirt - no further prep needed before assembly
• Skirt coating (depending on supplier) reduces friction and cylinder wear under high load or boost
• Balanced components to ensure consistent performance across all cylinders in a multi-piston set
• Designed for high-performance street or turbo-charged builds - suitable for GDI turbo upgrade or rebuild

Product Description

The JE Pistons 361285 is a complete forged piston kit specifically engineered for the 1.6 L Gamma GDI turbo engine used in newer Hyundai models (2013 and onward). Manufactured from high-strength 2618 alloy with JE's proven FSR forging process, these pistons provide robust strength and durability - ideal for turbocharged applications, high-performance builds, or upgraded GDI engines. The dish-style crown with -8.2 cc volume and 77.00 mm bore ensures correct compression geometry, while reducing risk under boost or high-load conditions.

Each piston comes fully machined, coated (where applicable), and ready to install, complete with piston rings, wrist pins, and locks. The reduced skirt width and lightened reciprocating mass improves throttle response and reduces friction - making the 361285 kit a solid choice for enthusiasts rebuilding or upgrading a Gamma-turbo 1.6 L engine for reliability and performance.
