Brand new Isuzu D-Max engine — the 4JJ1-TC 3.0L turbo diesel, for 2013–2021 models. Manual and auto versions both listed. Delivered anywhere in New Zealand.
What kills a 4JJ1
Three things, and they usually arrive together. The engine burns oil as the bores and rings wear, which shows up as blow-by through the breather and a haze out the back under load. The timing chain stretches and the guides wear — a 4JJ1 that rattles for a second on start-up is telling you something. And once oil consumption is up, the turbo and the intake side load up with oil and carbon. By the time all three are present, the rebuild quote is close to the price of a new engine with no history at all.
These are late-model utes doing real work in New Zealand, and the rest of the vehicle is normally sound. A new engine is the cheaper end of the decision.
Manual or auto — choose above
The manual and automatic versions are listed separately because they are not the same part. Pick the one that matches your gearbox. Send us your VIN or engine number if you are not certain and we will confirm it at no charge before you order.
This is a 4JJ1, not a 4JJ3
D-Max and MU-X models from 2020 onward run the 4JJ3-TCX, which is a different engine and is listed separately. If your build date puts you near the changeover, check the engine number before ordering rather than going by the year.
What you receive
A new long block. Your mechanic fits the timing chain and gears and transfers the alternator, brackets, intake and exhaust manifolds, turbocharger, injectors and the rest of the ancillaries from your original engine. Fit new fluids, filters and seals, and deal with whatever caused the first failure before the new engine goes in.
New, not reconditioned
Zero kilometres, no unknown history, no exchange unit and no core charge. 1-year warranty on manufacturing and assembly faults; professional installation required.
Delivery to New Zealand
Flat freight NZ$710 North Island, NZ$790 South Island, GST-exclusive, crated and insured, typically 5–8 business days door to door. Prices exclude GST; New Zealand Customs collects GST and entry fees on arrival.

Know what you're buying
New vs reconditioned crate engines
Plenty of engines sold into New Zealand are old, patched motors with new seals, called "remanufactured". Here's the honest difference with a brand new crate engine.
What we sell
Brand new crate engine
Built from new components only, to OEM+ specification, with the known factory weak points engineered out.
- Forged steel crankshaft, upgraded pistons, improved oil galleries
- Zero kilometres — no unknown history, no wear

- Heat tabs fitted for transparent warranty coverage
- 1-year warranty standard, 2–3 year Platinum available
- No exchange required — keep your old engine
The old way
Reconditioned / used
A worn core with new seals and gaskets — the internals, and the history, are whatever they are.
- Unknown kilometres, service history and prior abuse
- Original worn internals retained under new gaskets
- Rarely tested before sale — you're the test
- Core charges and exchange units required
- Typical warranty: 3 months, if any
- Early failures inherit the old engine's problems
Before you fit it
Plan the job around the whole vehicle
A new engine only lasts if the reason the old one failed is fixed. Your mechanic should check these before fitting.
Find the original cause
Overheating, cooling faults, blocked intakes or fuel issues that killed the old engine will kill the new one too. Diagnose and fix them first.
Check the parts you reuse
Radiator, hoses, injectors, turbo, intercooler and sensors carried over from the old engine should be inspected, cleaned or replaced.
Follow the fitting requirements
Fitted by a qualified mechanic with a tax invoice, correct fluids and a proper first start-up. This keeps your warranty active.

Before you buy
Engine replacement FAQs
Not sure this is the right engine? Send us your VIN or engine code and we'll confirm fitment before you pay.
Is this engine brand new?
Yes. Built from new components only — not reconditioned, not second-hand, zero kilometres.
What's included with the engine?
This is a long block. Accessories such as the turbo, injectors, pumps, sensors and manifolds are transferred from your existing engine unless listed otherwise. Check the description or ask us if unsure.
Will I pay GST or customs fees on delivery?
Yes. Prices are in NZD excluding GST. When the engine arrives, NZ Customs collects 15% GST plus an import entry transaction fee and biosecurity levy (around NZ$172 combined) before it is released. Engines are duty-free. You pay those charges directly to Customs, not to us.
How long does delivery to New Zealand take?
The estimated delivery window is shown next to the Add to cart button. We'll send tracking as soon as your engine is dispatched.
How does the warranty work?
1-year warranty covering manufacturing and assembly faults, with 2 and 3-year Platinum cover available. Installation by a qualified mechanic with a tax invoice is required to activate cover.
Do I need to send my old engine back?
No. No core charge and no exchange — keep or sell your old engine.
