Brand New G4FJ 1.6L Turbo Petrol Long Engine for Hyundai i30 PD 2018-2022

About this engine

An i30 PD with the 1.6 turbo is a quick, practical hatch — until the engine starts using oil, idling rough or knocking under load, and a workshop mentions the words “engine replacement”. For Hyundai i30 PD models built 2018 to 2022 with the G4FJ engine, this listing is the direct answer: a brand-new G4FJ 1.6L turbo petrol long engine, made to OEM specification, with no previous life behind it.

Every unit is subjected to hot and cold testing after assembly, before it is cleared to ship. Parts are warranted for 12 months or the first 50,000 km, delivery is free wherever you are in Australia, and we run a VIN check before purchase so the engine that arrives is the engine your i30 needs.

Common G4FJ failure patterns in the i30 PD

Rebuilding a modern turbocharged engine is a very different proposition from rebuilding the simple fours of decades past. The G4FJ combines direct injection, a turbocharger and tight factory tolerances, which means a proper rebuild involves specialist machining, a long parts list and labour hours that climb quickly. Worse, the quote you get at the start is provisional — nobody knows the true condition of the block, crank and head until the engine is fully stripped. Owners regularly discover that the final rebuild figure approaches, or passes, the cost of a new engine that carries a warranty.

The wear that brings a G4FJ to this point follows a pattern. Turbocharged engines generate higher cylinder pressures than atmo engines, so they punish stretched service intervals: oil that should have been changed thousands of kilometres ago loses its protective qualities exactly where the engine needs them most. Bearings and rings wear first, oil consumption rises, and the turbocharger — fed by the same oil — often deteriorates alongside. Direct injection adds its own signature, with carbon gradually accumulating on intake valves at higher kilometres.

A used engine dodges the rebuild bill but not the risk: you cannot see service history in a crated second-hand motor. A brand-new long engine settles the question. The cost is known upfront, every internal part starts unworn, and the 12-month or 50,000 km parts warranty stands behind it. For an i30 PD that is otherwise in good order, it is the repair that actually ends the problem.

Will it fit my i30?

The short answer: if your i30 PD was built between 2018 and 2022 and left the factory with the G4FJ 1.6-litre turbo petrol engine, this is the matching replacement. The longer answer is that we never leave fitment to a short answer. The i30 PD range included several engines across petrol and diesel, and within the G4FJ cars there can be build-level differences in brackets, sensors and fittings. So before an order is finalised, we ask for your 17-character VIN and verify the match against your specific vehicle. The check is free and quick, and it means the crate that arrives at your workshop bolts up the way it should.

About the engine itself: the G4FJ sits at the performance end of the Hyundai-Kia Gamma family. It is a 1.6-litre four-cylinder petrol unit with a turbocharger, direct fuel injection and chain-driven camshafts — no timing belt to schedule around. The chain design and the turbo both reward one habit above all others: on-time oil changes with the correct grade. That is worth remembering for the new engine's sake, because oil neglect is the most commonly reported road to early G4FJ failure.

This replacement is built new to OEM specification for fitment, and it has no accident history, no flood history, no unknown kilometres — the usual question marks that hang over any used engine simply do not exist here. Nor is it a straight reproduction of the factory engine: internals that showed documented weaknesses in the original design, the connecting rods, crankshaft and bearings among them, are made to a higher grade in this unit. Add a documented hot and cold test completed before crating, and you know precisely what is arriving.

What's included, what transfers, what it costs to ship

Included in the crate: a complete long engine, meaning the block assembled with crankshaft, pistons and connecting rods, plus the fully built cylinder head — one unit, already tested. Not included: the turbocharger, intake and exhaust manifolds, injectors, ignition coils, alternator, starter, sensors and external brackets. Those components transfer from your old engine during installation, which is standard practice and one of the reasons a long engine is the cost-effective format. Your mechanic should assess the transferred parts honestly, especially the turbo — bolting a tired turbocharger to a new engine is false economy.

Shipping is free to every corner of Australia, with the engine crated for transport. Most customers consign directly to their installing workshop; give us the workshop address when ordering and we will arrange it. Nothing about freight is added at checkout — the listed price is the delivered price.

Warranty runs 12 months or 50,000 km on parts, whichever comes first, on two conditions. Installation must be performed by a qualified mechanic, and the engine must never be overheated — a heat tab fitted to the block records any overheating event permanently, and heat damage is excluded from cover. Practical advice follows from that: renew the cooling system during the swap, prime the oil system before first start, and bring the first oil change forward.
