Engine failure is one of the most expensive surprises a car owner can cop, and the first question is always the same: what’s this going to cost me? Prices quoted around Australia vary wildly — partly because “reconditioning” covers several different jobs, and partly because the damage inside your engine decides half the bill. Here’s a realistic breakdown based on what these jobs actually cost in 2026.
The short answer: Reconditioning (rebuilding) a typical four-cylinder engine in Australia costs around $3,500–$5,500 including parts, machining and labour. Buying an exchange reconditioned engine instead typically runs $4,200–$7,999 for Hyundai and Kia units, plus fitting. Severe internal damage, diesel engines and turbo engines all push costs higher.
What does it cost to recondition your own engine?
Reconditioning your existing engine means removing it, stripping it to a bare block, machining the block, crank and head as needed, and reassembling it with new bearings, rings, gaskets, seals and timing components. It’s a labour-heavy job — a full rebuild takes roughly 15–25 hours of workshop time on top of machining and parts.
For a common Hyundai or Kia four-cylinder, expect roughly $3,500–$5,500 all up in Australia. At Hyun Engines, a typical full engine rebuild comes in around the $4,000 mark for most four-cylinder Hyundai and Kia models, depending on what the strip-down reveals. Simple bottom-end wear sits at the lower end; scored cylinders needing a rebore, a damaged crank or cylinder head work push you toward the top end and beyond.
What does an exchange reconditioned engine cost?
The alternative is skipping the wait and buying an engine that’s already been reconditioned and tested — your old engine comes out, the exchange unit goes in. Our reconditioned Hyundai and Kia engines range from $4,200 to $7,999 depending on the engine family, with common units like the i30’s G4NB and G4NC sitting toward the lower-middle of that range and larger diesel engines at the top. Every engine carries a 12-month warranty. You can see current pricing for your model in the online shop.
On paper the exchange engine can look dearer than a rebuild, but compare like with like: the exchange price includes all the machining and parts already done, and your car is off the road for days instead of weeks.
How do the options compare?
| Option | Typical cost (AU 4-cyl) | Downtime | Notes |
|---|---|---|---|
| Recondition / rebuild your engine | $3,500–$5,500 (around $4,000 at Hyun Engines for most models) | 1–3 weeks | You keep your original engine; final price depends on what the strip-down finds |
| Exchange reconditioned engine | $4,200–$7,999 plus fitting | A few days | Already machined and tested; 12-month warranty; fastest reliable fix |
| Second-hand engine | $1,500–$4,000 plus fitting | A few days | Unknown internal condition; short warranty if any |
| New engine from dealer | $10,000–$28,000+ | Varies with supply | Rarely economical outside near-new vehicles |
What factors move the price up or down?
Extent of internal damage. This is the big one. Worn bearings and tired rings are routine; a crank that’s been run dry, cracked block webbing or deeply scored bores mean more machining, oversize parts or even a replacement block.
Engine type. Diesels (like Hyundai’s D4HB 2.2 CRDi) and turbo petrol engines cost more to recondition than a simple Gamma 1.6 — more parts, tighter tolerances, and injectors or turbos that may need attention at the same time.
Parts availability. Common Hyundai and Kia engines enjoy good parts supply in Australia, which keeps costs predictable. Odd variants can add both cost and waiting time.
Labour rates. Workshop rates run roughly $100–$150 per hour in metropolitan Australia, so a job needing 20+ hours moves quickly with the hourly rate.
What failed alongside the engine. Radiators, engine mounts and clutches are often replaced while everything is out. Budget a few hundred dollars for sensible while-you’re-in-there items.
Is reconditioning worth it, or should you sell the car?
The maths usually favours fixing when the car is otherwise sound. A $4,000–$6,000 spend on a Hyundai i30 or Tucson that’s worth $12,000 running — and near-scrap value with a dead engine — buys you years of extra service for far less than changing cars, especially once stamp duty, dealer margins and the unknowns of a different used car are counted. It stops making sense when rust, transmission problems or accident damage mean you’d be pouring money into a car with multiple endings ahead of it. If you’re weighing it up, our guide to Hyundai engine rebuilds walks through the decision in more detail.
What about fitting costs?
If you buy an engine outright, allow for removal and installation on top — typically $1,000–$2,500 depending on the vehicle. The simpler path is a package: our engine supply and fit service covers the reconditioned engine, installation at our Dandenong workshop, fluids and testing in one quoted price, so there’s a single business responsible for the whole job.
Hyun Engines has been supplying and fitting reconditioned Hyundai and Kia engines since 2014 from 8 Hammond Rd, Dandenong VIC 3175. Every engine comes with a 12-month warranty. For a fixed quote on your exact model, call (03) 9630 0960, Monday to Friday 9am–5pm.
Frequently Asked Questions
Why do quotes for the same engine job vary so much?
Because “recondition” isn’t a fixed scope. One workshop may quote a re-ring and bearings; another quotes full machining with new timing components. Always compare the parts list and machining included, not just the bottom line.
Is it cheaper to rebuild my engine or buy an exchange engine?
They often land within a thousand dollars of each other for common four-cylinders. Rebuilds can win on price if your engine’s damage is minor; exchange engines win on speed and price certainty because the work is already done and tested.
How long does an engine rebuild take?
Typically one to three weeks including machining time, depending on parts availability and what the strip-down reveals. Fitting an exchange reconditioned engine usually has the car back on the road within days.
Does a reconditioned engine come with a warranty?
From a reputable supplier, yes. Every reconditioned engine from Hyun Engines includes a 12-month warranty, and supply-and-fit jobs are covered as a complete package.
