The G4FA/G4FC engine bare cylinder block supplied by WideEngine is designed for professional engine rebuilding and aftermarket replacement. Manufactured to OEM specifications, this aluminum engine block is intended for Hyundai–Kia Gamma 1.4L/1.6L engines where the original block is worn, cracked, or no longer suitable for machining. The product is delivered as a bare block only, allowing rebuilders full control over internal component selection and assembly quality.
Key Features Include:
The G4FA and G4FC are Hyundai–Kia Gamma inline-four gasoline engines. If the original block is worn, cracked, or deformed due to overheating or lubrication failure, replacement is often more reliable than re-boring or sleeving.
WideEngine supplies a dedicated bare aluminum cylinder block for G4FA and G4FC engine rebuilding. Key surfaces, including cylinder bores, crankshaft journals, oil passages, and deck surfaces, are machined to OEM dimensional standards. OEM or standard aftermarket internal components can be installed without modification.
This product is supplied as a bare block only. No pistons, crankshaft, bearings, or auxiliary parts are included. Professional builders prefer this format for full control over parts selection and assembly quality.
Target Buyers and Distribution Model
This product is intended exclusively for B2B customers, including engine rebuilding workshops, repair shops, and aftermarket distributors. WideEngine supports both single-engine repair demand and small-batch stocking under a wholesale supply model.

The G4FA/G4FC engine bare cylinder block is a lightweight aluminum block used in Hyundai and Kia’s Gamma engine family. The G4FA is a 1.4L naturally aspirated inline-4 engine, while the G4FC is a 1.6L version. These blocks share core dimensions, making them compatible with both engine variants, but require matching internals (pistons, crankshaft, etc.) for proper function.
Commonly found in models like the Hyundai Accent, i20, i30, Elantra, and Kia Cee’d, Forte, these bare blocks serve as replacements during engine rebuilds, repairs, or custom builds. They provide an OEM-spec foundation for restoring engine performance or achieving custom modifications.
The G4FA / G4FC cylinder block adopts an aluminum construction to balance strength, heat dissipation, and overall engine weight. The internal structure is designed to maintain bore stability under operating temperature changes while supporting the crankshaft and reciprocating components with consistent alignment.
Key structural features include accurately machined cylinder bores, reinforced main bearing saddles, and precisely formed oil passages to support proper lubrication flow. The deck surface is finished to OEM flatness requirements, allowing correct sealing with standard cylinder head gaskets. All mounting points and threaded holes are positioned according to original factory drawings to ensure straightforward installation during assembly.
