The question people ask before buying is “what does it cost to buy?” The question they should ask is “what does it cost to keep?”
This guide answers the second one. It covers what to do in your first month of ownership, what recurs annually, what’s waiting for you at longer intervals, and roughly what to budget.
On the numbers: every figure here is an indicative Australian estimate in AUD, and ranges are wide for good reason — RB20 parts differ from RB26 parts, GT-R components cost more than GTS-T equivalents, and labour rates vary enormously between a specialist and a general workshop. Where genuine parts are realistically available we’ve priced genuine; for several common wear items (the radiator, the fuel pump, brakes, the clutch) new genuine stock has effectively run out, so those figures reflect a quality aftermarket alternative instead — our faults guide explains which is which and why. Use these to build a budget, not to argue with a quote. One thing to watch: our faults guide links to eBay’s US site for genuine parts (priced in USD, shipped internationally) and eBay Australia for aftermarket parts (AUD, local stock). The figures below are what you should expect to actually pay landed in Australia, not the USD sticker price.
Month one: the catch-up
An imported car arrives with an unknown recent history, regardless of how good the Japanese service records look. These are the jobs that establish your baseline.
Priority 1 — Timing belt, if undocumented (RB20/RB25)
Do this before anything else if you can’t prove when it was last done.
The RB20 and RB25 are interference engines. If the belt breaks, the pistons meet the valves and the engine is finished. A belt that’s been sitting for years in a car awaiting export is not a belt you gamble on.
Do the water pump at the same time — the labour overlaps almost entirely, so doing them separately means paying for the same disassembly twice. Genuine pumps are still available: 21010-58S25 for the R32 GT-R, 21010-21U26 for R33 onward. Avoid the N1 pump (21010-24U27) unless you’re building for track use.
Search genuine Nissan water pumps (21010-21U26 / 21010-58S25) on eBay US Replace the front and rear crank seals and cam seals while everything is apart, for the same reason — genuine seals are a few dollars each and still readily available.
- Genuine parts: AUD $180–$450
- Labour: AUD $600–$1,200
- Interval thereafter: commonly quoted as around 100,000 km, but time matters as much as distance on a car this age and recommendations vary by engine and by workshop. Confirm the interval for your specific engine with a workshop familiar with RB engines rather than relying on a general figure
Note: RB26 engines use a timing belt as well and require the same treatment. Non-turbo RB20DE cars are also interference engines. This isn’t a turbo-only concern.
Priority 2 — Full fluid change
Whatever the seller says, start your own clock. Engine oil and filter, coolant, brake fluid, gearbox and differential oil.
- DIY parts cost: AUD $200–$400
- Workshop: AUD $400–$800
Use genuine filters. Genuine Nissan oil filters have the correct anti-drainback valve specification for RB engines — a detail that generic filters frequently get wrong, and one that affects oil pressure on startup. Good news here: unlike most of the parts on this page, the genuine RB20/RB25 filter is still in production and costs around USD $16 with the drain plug washer.

Priority 3 — Cooling system inspection
Squeeze every hose while the engine is cold. Perished rubber and internally silted radiators look fine from outside, and Australian summers are harder on an imported cooling system than the climate it was built for.
If hoses are hard or spongy, plan to replace all the affected ones rather than just the worst. Nissan supplies these individually by part number, so budget per hose rather than expecting a kit.
- Genuine hoses: roughly $20–$30 each; AUD $80–$250 to refresh the main ones
- Radiator, if needed: new genuine/Calsonic units aren’t realistically available for these chassis. Budget AUD $250–$550 for an aftermarket aluminium radiator from an established brand. Manual cars only for the well-known options, and R33 GT-R requires modification — see our faults guide before ordering
Priority 4 — Ignition service
If you heard ticking at idle during your inspection, or the car has an unknown history, budget for a full set of six coil packs and a set of plugs. This is the most commonly reported fault on RB engines and it’s cheaper to address on your terms than on the side of a road.
- Ignition coils (set of six): R33 Series 2 only — genuine Nissan coils (22448-25U00) are still available, around AUD $220 each, so roughly $1,100–$1,300 for a set of six. R32 owners and R33 Series 1: this part doesn’t fit; budget $400–$800 for an aftermarket set. See our faults guide — the fitment traps here are worth reading before you order
- Spark plugs (set of six): genuine NGK is readily available if you search the part number — BCPR6ES for a stock or near-stock engine, BCPR7ES only for 500hp-plus builds. Budget AUD $60–$150
Realistic month-one total: AUD $1,500–$3,500 for a car with unknown history, less if the timing belt is documented.
Every service interval
Treat these as your normal rhythm. These are conservative suggestions for a thirty-year-old car in Australian conditions, not Nissan’s published service schedule — they’re deliberately shorter than factory intervals were. Check your engine’s documented specification and your workshop’s advice, particularly for the timing belt.
| Item | Interval | Genuine parts cost |
|---|---|---|
| Engine oil + genuine filter | 5,000 km or 6 months | $50–$120 |
| Air filter (genuine 16546-V0100) | 20,000 km | $40–$90 |
| Spark plugs | 20,000–40,000 km | $60–$150 |
| Brake fluid | 2 years | $30–$60 |
| Coolant | 2–3 years | $60–$120 |
| Gearbox + diff oil | 40,000–60,000 km | $120–$250 |

Why shorter oil intervals than modern cars? Turbocharged RB engines run hot, thirty-year-old engines have more blow-by than new ones, and — on GT-Rs specifically — the RB26’s oil pump drive is a documented weak point where clean oil and proper warm-ups measurably extend engine life. Frequent oil changes are the cheapest insurance available on these cars.
Fluids: buy to specification, not to brand
Unlike the parts above, the fluids have no meaningful “genuine or nothing” question — Nissan specified a standard, and any reputable oil meeting that standard is correct. These are all readily available in Australia, so there’s no reason to import them.
| System | Specification | Capacity (R32/R33) |
|---|---|---|
| Manual gearbox | GL-4 75W-90 | 4.1 L |
| Rear differential (LSD) | GL-5 80W-90 LS | 1.5 L |
| Front differential (GT-R) | GL-5 80W-90 | 1.0 L |
| Transfer case (GT-R) | Nissan Matic D (ATF) | 1.8 L |
| Brake and clutch fluid | DOT 4 | — |
| Coolant | — | approx. 9 L |
The one mistake that costs you a gearbox. The differential takes GL-5; the gearbox must take GL-4, not GL-5. GL-5 gear oils contain reactive sulphur additives that attack the brass synchro rings in an RB five-speed. The damage is gradual — crunchy shifts that get worse over months — so by the time you notice, it’s done. Buy two different oils and label them.

Annual budget
A well-sorted, road-driven car, moderate mileage:
| Category | Annual |
|---|---|
| Servicing (fluids, filters, consumables) | $400–$800 |
| Registration and CTP | varies by state |
| Insurance (agreed value recommended) | $800–$2,500+ |
| Contingency for age-related faults | $1,000–$2,000 |
| Total, excl. rego/CTP/fuel | $2,200–$5,300 |
On insurance: agreed-value classic or enthusiast policies are a common choice for these cars, because market-value policies on a thirty-year-old import can produce an unpleasant surprise at claim time. Premiums vary substantially with driver age, location, storage and declared modifications. CTP (compulsory third party) arrangements differ significantly between states and territories — in some it’s bundled with registration, in others you choose an insurer separately — so the total varies more by where you live than most cost guides admit. Declare modifications: undeclared changes are a common reason claims get refused. We’re not insurance advisers; compare policies and read the product disclosure statement.
On the contingency line: this isn’t padding. On a car this age something will need attention each year. Owners who budget for it find ownership relaxed; owners who don’t find it stressful.
The longer-interval items
These don’t come up every year, but they arrive eventually and they’re the four-figure ones.
Clutch (manual cars). Typically 80,000–150,000 km depending on use and previous owners. New genuine clutch kits are not realistically available for these chassis. Exedy — a respected Japanese clutch manufacturer — makes a direct-fit standard kit (disc, cover and release bearing) under part number NSK-7056, covering R32 and R33 GTS/GTS-T with RB20DET or RB25DET, plus the R32 GT-R. One trap: the R32 GT-R uses a push-type clutch while the R33 GT-R uses a pull-type — they are not interchangeable, and a listing that says “R32 R33 GT-R” may only cover one of them. Confirm push or pull before ordering. Exedy also sells a “Sport Tuff” heavy-duty version aimed at higher-power builds; skip it unless your car is genuinely modified beyond stock output, since a heavy-duty clutch on a stock engine mainly adds pedal effort. Budget $260–$450 in parts, plus substantial labour — the gearbox has to come out.

Suspension bushings. Thirty-year-old rubber is thirty-year-old rubber, and worn bushings are a real contributor to vague, imprecise handling. New genuine rubber bushings for these chassis are not realistically available; what’s available is polyurethane, sold by location (front steering rack mounts, sway bar mounts, control arms) rather than as one universal kit — expect to search and order a few separate items rather than a single “full set”. Polyurethane is firmer than the original rubber: it sharpens handling but transmits more road noise and a harsher ride than the car had when new, which is worth knowing before you commit to a full-car refresh rather than just the worst-worn bushings. Budget $250–$600 in parts across the locations you replace, significant labour.

Brakes. Pads and rotors wear and need periodic replacement. New genuine pads and rotors are not realistically available for these chassis. Pads and rotors tend to come from different aftermarket brands rather than one matched set — DBA (Australian) makes a direct-fit front pad (DB1170 series) covering R32 GTS-T and R32 GT-R on Sumitomo calipers, R33 GTS25T and R34 GTT, and Protex makes a direct-fit front rotor. Caliper type decides fitment here, not chassis code: R32 GT-R V-Spec, R33 GT-R and R34 GT-R run Brembo calipers and take a different pad and a 324mm rotor. Check which calipers your car actually has before ordering. Budget $250–$700 per axle across the pair. One trap to watch for here too: a listing that says “Genuine Bendix” or similar means genuine Bendix, not genuine Nissan — same pattern as “Genuine Walbro” earlier in this guide.

Fuel pump. Aging in-tank pumps cause hesitation and hard starting. This is one to plan ahead for: new genuine pump assemblies for these chassis are difficult to source — most of what’s listed online is either used genuine, an aftermarket high-flow pump, or a genuine part for an entirely different Nissan. Check availability with a genuine-parts specialist before you need one. Our faults guide covers the realistic aftermarket options (this is one of several wear items — along with the radiator, brakes and the clutch — where genuine stock has effectively run out) — discuss any of them with a workshop rather than guessing. Whichever route you take, replace the fuel tank pump seal O-ring at the same time — that one is still available new and genuine, and it’s a few tens of dollars. Budget $150–$400 for a pump, more if you’re chasing a genuine unit.
Turbocharger. The factory ceramic turbine wheels are known to break up with age and heat cycles. This is a when-not-if item on a high-kilometre car, and repairs run into the thousands. It’s also the one area where many owners deliberately move away from the factory design — a decision to make with a specialist rather than from a parts list.
HICAS four-wheel steering. Rear rack seals leak, solenoids fail, toe-control hardware wears. Repair costs vary widely with what’s actually failed, so diagnose before ordering parts. Note that the community’s common alternative — a lock-bar delete — is a modification to a steering system, with compliance and insurance implications. Whether it’s permitted, and whether it requires engineering certification, differs between states and territories. Check your own state or territory’s requirements before going that route, and be aware it may affect registrability if you move interstate.
Three things that lower your costs
Drive it regularly. Cars that sit develop more problems than cars that are used. Seals dry out, fuel goes stale, batteries die, brakes seize. If the car will sit for weeks at a time, a trickle charger is worth the small investment — CTEK and NOCO Genius are the two widely trusted names in Australia.

Warm it up properly. Particularly on turbocharged and RB26 cars. Oil needs to be at operating temperature before the engine works hard. This is widely held among owners and specialists to extend the life of expensive components — treat it as sound practice rather than a measured guarantee.
Fix things when they’re small. Every four-figure repair on this page started as a cheaper symptom. A misfire ignored destroys a catalytic converter. A slow coolant weep ignored warps a head. The owners with the lowest running costs are the ones who investigate noises early.
The honest summary
An R32 or R33 in good condition, driven regularly and maintained properly, costs roughly $2,000–$5,000 a year to run excluding registration, CTP and fuel — with occasional larger years when a clutch, turbo or suspension refresh lands. Registration and CTP vary enough between states that including them in a single national figure would be misleading.
That’s not cheap transport. It’s also not exotic-car money, and it’s entirely predictable if you buy the right car in the first place.
Which is why the money that matters most is the money you spend before you buy — on a proper inspection, or on a purchase channel where that verification has already happened.

All figures are indicative Australian estimates and vary with model, engine, supplier, exchange rate and labour rates — treat them as a budgeting starting point, not a quote. Service intervals here are conservative suggestions, not manufacturer specifications; confirm against your engine’s documentation and a qualified workshop. Registration, CTP, roadworthy standards and rules on modifications are set by each state and territory and change over time — confirm current requirements with your own state or territory road authority.
