Used Nissan RD28 Engine for Sale – 5 Proven Checks Before You Buy

If you’re shopping for a Used Nissan RD28 Engine for Sale, you already know this isn’t the easiest engine to track down in good condition. Production was relatively short, listings are scattered across a handful of specialist forums and marketplaces, and a lot of sellers can’t actually tell you whether what they’re selling is the naturally aspirated version or the turbo. We built our process to cut through that. We pull RD28 engines, run compression and a leak-down check, verify which variant we’re actually looking at, and crate them for shipment anywhere in the world.

The RD28 has a well-earned reputation among Nissan Patrol owners — it’s not the most powerful engine Nissan ever built, and we’re not going to pretend otherwise, but it’s a known quantity with a loyal following among people restoring or maintaining classic Patrols, Laurels, and Cedrics who want to keep the driveline original rather than swapping to something newer.

When people search for a used Nissan RD28 engine for sale, they’re usually trying to avoid two things: an engine with a cracked head or a weeping gasket that the seller didn’t disclose, or a “complete” engine that’s actually missing the injection pump or turbo. This page covers the real specifications, what tends to fail on this engine, and exactly how we prepare every unit before it ships.

We hear from restorers and Patrol owners worldwide who’ve been burned before — an engine sold as “runs great” that had a cracked cylinder head the seller either didn’t know about or didn’t mention, or a crate that arrived missing the fuel injection pump entirely. When you buy a used Nissan RD28 engine for sale from us, you’re working with a shop that actually inspects what it sells, not a listing that goes quiet the moment your payment clears.

What Is the Nissan RD28 Engine?

The RD28 is a 2.8-liter inline-six engine with an unusual heritage: it was actually developed from Nissan’s RB-series inline-six petrol engines, adapted into a diesel configuration and sharing the same bell-housing pattern, engine mounts, and basic cast-iron block design as its petrol cousins. It runs a single overhead camshaft with two valves per cylinder, a straightforward, mechanically simple layout by modern standards, which is part of why these engines are still running in original Patrols decades later.

Nissan built two distinct versions worth knowing apart. The naturally aspirated RD28 was fitted mainly to Laurels, Cedrics, Skylines, and early Patrol GQ (Y60) models. The RD28T added a turbocharger and intercooler for meaningfully more power and torque, and that’s the version most commonly associated with the later GQ and GU (Y61) Patrol, sold in some markets as the Safari. If you’re not sure which one your vehicle takes, check the engine code stamped on the block, since the two are not interchangeable without also swapping the turbo plumbing, intercooler, and related fuel system components.

Nissan RD28 Engine Specifications

Here’s what you’re actually getting when you buy a used Nissan RD28 engine for sale from us. Figures vary meaningfully between the naturally aspirated and turbocharged versions, so we’ve listed both below.

Specification	RD28 (Naturally Aspirated)	RD28T (Turbo Intercooled)
Displacement	2.8L (2,826 cc)	2.8L (2,826 cc)
Bore x Stroke	85mm x 83mm	85mm x 83mm
Valvetrain	SOHC, 2 valves per cylinder	SOHC, 2 valves per cylinder
Power output	94 PS / 92 hp (69 kW) @ 4,800 rpm	Approx. 135–145 PS (99–107 kW) @ 4,000 rpm
Torque	177 Nm (130 lb-ft) @ 2,400 rpm	Approx. 261–287 Nm (192–212 lb-ft) @ 2,000 rpm
Applications	Laurel, Cedric/Gloria, Skyline R31, Patrol GQ (early)	Patrol GQ (Y60), Patrol GR/Safari (Y61)

Factory tunes for the Australian-market Patrol varied somewhat between the GQ and GU generations, so if you’re trying to match power figures exactly to your logbook, send us your VIN or chassis details and we’ll confirm the specific tune before anything ships. For more background on this engine’s unusual development history, see the Nissan RD engine family overview.

Where the RD28 Actually Gets Used

The RD28T is best known as the diesel option in the Nissan Patrol GQ (Y60) and the later GR/Safari (Y61), sold across Australia, the Middle East, and other four-wheel-drive markets where the Patrol built its reputation. The naturally aspirated RD28 saw broader use across Nissan’s passenger car lineup of the era, including the Laurel (C32–C34), Skyline R31, Cedric/Gloria (Y30–Y33), Cefiro A31, and the Crew K30, mostly in markets where diesel passenger cars were common.

Because production ran for a relatively short window before Nissan moved on to the TD42 and later engines, the pool of donor vehicles is smaller than for more common engines we carry, which is exactly why sourcing a properly tested used Nissan RD28 engine for sale matters more here than it does for engines with a bigger supply. We source from multiple donor vehicle types and verify the specific variant before listing.

Being Honest About the RD28’s Reputation

We’d rather tell you upfront what you’re getting into than have you find out after the sale. The RD28T earned a mixed reputation in the Australian 4×4 community — slow turbocharger boost buildup gives it noticeable throttle lag, and a lot of owners describe it as underpowered for hauling a Patrol’s roughly 2.3-tonne weight around, particularly compared to later diesel options.

It’s not a fast engine, and we’re not going to market it as one.

What it does have going for it is mechanical simplicity and a loyal following among people who want to keep an original Patrol, Laurel, or Cedric running with its factory driveline rather than swapping to something newer. If originality or a period-correct restoration matters to you more than outright power, the RD28 still makes sense. If you’re after more power for serious off-road work, we’re happy to talk through later Patrol diesel options that might suit you better.

Common RD28 Engine Problems We Check For

The front crankshaft pulley is the single most talked-about issue on this engine — it can work loose over time, and if it’s not caught early, the resulting damage to the crankshaft snout can turn a simple fix into a serious repair. We check pulley torque and crank snout condition on every RD28 before it’s listed. Cracked cylinder heads and weeping head gaskets are the second issue worth knowing about, both of which we specifically pressure-test for rather than just checking for visible leaks.

The fuel injection pump is the third area we watch closely, since RD28 injection pumps have a reputation for being both troublesome and expensive to replace if they fail. We test injection pump performance and document its condition on every engine we sell. Because parts availability for this engine is more limited than for more common Nissan diesels, we’d rather catch and disclose an issue now than have you discover it after installation with no easy fix available.

How We Prepare Every RD28 Before It’s Listed

Before a used Nissan RD28 engine for sale goes live on our site, it goes through a defined process in our shop. We start with a visual inspection for oil and coolant leaks, paying particular attention to the head gasket area given this engine’s known history. We check the front crankshaft pulley torque and inspect the crank snout, pull a compression test across all cylinders, and test the fuel injection pump’s performance. On turbo variants, we also check the turbo for shaft play and inspect the intercooler and associated plumbing for leaks or corrosion.

If anything comes up short during that process, we address it before listing, not after you’ve already paid to ship it home. Every used Nissan RD28 engine for sale that leaves our shop comes with a written summary of our findings and photos taken during inspection, which matters even more on an engine this old.

Used vs. Rebuilt: What Makes Sense for This Engine

Given how limited new-old-stock and remanufactured options are for an engine this old, most RD28 buyers are choosing between a tested used unit and a professionally rebuilt one rather than a factory remanufactured engine. A tested used RD28 — verified for compression, pulley condition, and head integrity — is the more practical and affordable option for most restorations and replacements. A full rebuild, where the head is machined, the pump is overhauled, and wear components are replaced, costs considerably more but makes sense if you’re doing a complete restoration and want the engine to match the rest of the work.

If you’re restoring a Patrol, Laurel, or Cedric and trying to decide how much to invest in the engine relative to the rest of the vehicle, tell us your plans and budget and we’ll help you figure out which approach fits your project.

Shipping a Used Nissan RD28 Engine for Sale Worldwide

We ship RD28 engines internationally on request, crated on a pallet and strapped down so freight handlers can move them with standard equipment on either end. Whether you’re in Australia, the Middle East, Europe, North America, or elsewhere in the classic Nissan community, we can get a used Nissan RD28 engine for sale to your door or your nearest freight terminal. We handle export paperwork and coordinate directly with your freight forwarder, and every engine is photographed again immediately before crating so you have a clear record of exactly what shipped.

Because this is an older engine with more variation between individual units than a modern common-rail diesel, we’re especially thorough about documenting exactly what you’re getting — naturally aspirated or turbo, which accessories are included, and what condition the injection pump is in — before you commit to a purchase.

What to Check Before You Buy Any Used Classic Diesel

Whether you buy from us or anyone else, here’s what actually separates a legitimate seller from someone flipping an old engine with no real information: confirm whether it’s the naturally aspirated RD28 or the turbo RD28T, since a lot of casual listings get this wrong. Ask specifically about the front crankshaft pulley and crank snout condition, ask whether the head has been pressure-tested for cracks, and ask about the fuel injection pump’s condition and history.

We answer all of these questions directly because we check every one of these items ourselves before anything goes up for sale. If a seller can’t tell you which variant they’re selling or speak to the pulley and head condition specifically, that’s a strong sign they haven’t actually inspected what they’re offering.

RD28 vs. TD42: Which Nissan Diesel Fits Your Project?

A lot of people shopping for a used Nissan RD28 engine for sale are also weighing it against the later TD42, and it’s worth understanding the real difference before you commit. The RD28 is a lighter, mechanically simpler inline-six built primarily for passenger cars and the earlier Patrol GQ, while the TD42 is a heavier, torquier engine built specifically for serious 4×4 and commercial duty in the Patrol GU and related trucks.

If you’re restoring an early GQ Patrol, a Laurel, a Cedric, or a Skyline and want to keep the driveline period-correct, the RD28 or RD28T is the right call. If you’re building a Patrol for heavy off-road work, towing, or commercial use and originality isn’t the priority, the TD42’s extra torque and simpler mechanical fuel injection make it the more practical swap candidate, even into a chassis that originally came with an RD28.

We carry both engines and can talk through which one actually fits your vehicle and how you plan to use it, rather than just selling you whichever one you asked about first.

RD28 Engines in Marine and Light Industrial Use

Outside of Patrols, Laurels, and Cedrics, we occasionally get inquiries from boat owners and small industrial operators looking at the RD28 as a marine conversion or generator base. The inline-six layout, simple SOHC valvetrain, and mechanical fuel system make it a reasonable candidate for a marinization project if you already have experience with diesel conversions, though it’s a less common choice than purpose-built marine diesels. If this is your plan, talk to us before you buy so we can confirm which specifics matter for your application — cooling system compatibility and mounting orientation are the two issues that come up most often with automotive-to-marine diesel swaps, and it’s much cheaper to sort those out before the engine ships than after.

Parts and What Ownership Actually Involves

We’ll be straightforward here: parts availability for the RD28 is more limited than for Nissan’s later diesel engines, a direct result of its relatively short production run. Common wear items and gaskets are still sourceable through specialist suppliers and the classic Nissan community, but you shouldn’t expect the same walk-into-any-parts-store availability you’d get with a TD42 or a more modern common-rail engine. This is exactly why we document engines thoroughly and keep spares knowledge in-house — when parts are harder to find, knowing the specific condition of what you’re buying matters even more.

Owners who stay ahead of pulley torque checks and don’t ignore early signs of head gasket weeping get a long service life out of this engine despite its age. If you’re outside our immediate service area and need help sourcing parts or diagnosing an issue, we maintain relationships with specialist shops in the classic Nissan community and can point you toward someone who knows this engine well.

Why Buy This Used Nissan RD28 Engine for Sale From Us

Finding a properly tested RD28 isn’t easy, and a lot of what’s out there comes with vague descriptions and no real inspection behind them. Every used Nissan RD28 engine for sale we list has been checked for pulley and crank snout condition, pressure-tested for head cracks, and had its injection pump tested for performance, all documented in writing before the engine ships anywhere.

We also don’t disappear once your payment clears. If you have a question about which accessories are included or need documentation for a restoration project, you can call and get an answer from someone who actually inspected that specific engine. Pricing reflects condition, documented history, and the work already done — current inventory and pricing are on our site, and we’re happy to answer questions before you commit to anything.

Frequently Asked Questions

Is this used Nissan RD28 engine for sale tested before it ships?
Yes. Every engine gets a compression test, a check of the front crankshaft pulley and crank snout, a head pressure test, and an injection pump performance check before it’s listed.

Is this the naturally aspirated RD28 or the turbo RD28T?
Our listings specify exactly which variant you’re getting. Send us your VIN or engine code and we’ll confirm before you order.

Why is the RD28T considered underpowered?
It was never a high-output engine, and moving a roughly 2.3-tonne Patrol around means the turbo lag and modest output are more noticeable than they would be in a lighter vehicle. It remains a solid choice for owners prioritizing originality over performance.

Will the engine include the fuel injection pump?
Listings specify exactly what’s included. Given how expensive this component is to source separately, we confirm this detail with every buyer before the sale.

Can you ship to a freight forwarder instead of directly to me?
Yes — that’s a common way these engines move internationally. Send us your forwarder’s details and we’ll coordinate delivery directly with them.

Do you offer a warranty?
Every used Nissan RD28 engine for sale we ship comes with a warranty covering the work we’ve done and the components we’ve inspected.

Should I buy used or have it rebuilt?
It depends on your project and budget. A tested used engine works well for most replacements; a full rebuild makes more sense for a complete restoration. We can help you decide based on your specific plans.
