Nissan Skyline specialist UK — R32 to R35 and Z-cars.

Why these cars need a specialist

The Nissan GT-R family is among the most technically complex Japanese performance cars in the independent market. The R32, R33 and R34 generations with the RB26DETT inline-six twin-turbo, the R35 with its VR38DETT and its proprietary dual-clutch transaxle, the 350Z and 370Z with naturally aspirated V6 engines — each requires specific knowledge. A garage unfamiliar with these platforms will apply generic service procedures that miss the critical items, or worse, apply incorrect fluids to systems that are sensitive to specification.

We work on these cars regularly, largely because of our import servicing background. The majority of R32, R33 and R34 Skylines in the UK arrived as imports from Japan, and the R35 GT-R was sold in meaningful numbers here from 2009 onward. Knowing these cars is part of what we do.

RB26 and the older Skylines

The RB26DETT in the R32, R33 and R34 GT-R is a robust engine with well-documented service requirements. The head gasket is the primary structural concern on any high-mileage RB26 — the six-cylinder inline layout and the twin-turbo heat loading create conditions where a gasket past its service life will begin to weep between cylinders, typically showing first as slightly elevated coolant consumption or subtle combustion contamination in the coolant. We do not assume a head gasket is fine on an unknown-history RB26; we baseline the coolant and run a combustion gas test as part of any first inspection.

Cooling system maintenance on the older Skylines — R32, R33 and standard R34 models — follows similar principles to other high-output Japanese engines from this era: correct coolant specification, attention to the radiator condition, and thermostat integrity. Japanese cars of this age often have original cooling components that have not been replaced because they have not obviously failed. Preventive cooling system work on a car with over 100,000 kilometres is money well spent.

The older Skylines also benefit from regular differential fluid changes — both the front and rear units on the ATTESA four-wheel-drive system. We include differential fluid condition in the inspection on any AWD Skyline that comes through.

R35 GT-R specifics

The R35 GT-R uses a completely different architecture to its predecessors. The VR38DETT is a twin-turbocharged 3.8-litre V6, and the gearbox is a dual-clutch transaxle mounted at the rear. Both the engine and the transmission have specific service requirements and specific consequences for running incorrect or degraded fluids.

The R35's transaxle fluid and transfer case oil are items that owners frequently defer because the car's performance does not obviously degrade until the degradation is significant. We service R35 transmission systems with the same approach as any complex dual-clutch unit: fluid and filter change at sensible intervals, condition assessment, and a diagnostic check of the transaxle control systems. These are not jobs for a generic auto-gearbox service.

Engine oil on the R35 must meet Nissan's GT-R specification. The turbochargers on the VR38DETT are directly oiled, and contaminated or incorrect-specification oil shortens bearing life. We do not accept substitutions here.

350Z, 370Z and Silvia

The 350Z and 370Z carry the VQ35DE and VQ37VHR naturally aspirated V6 engines respectively. Both are well-regarded engines with a reputation for longevity when maintained correctly. The VQ35 has a known tendency toward oil consumption on higher-mileage examples — something worth understanding before servicing and tracking over time. Both Z-cars benefit from gearbox oil changes at sensible intervals; Nissan's factory schedule is conservative and real-world experience suggests earlier changes maintain the shift quality these cars are known for.

The Silvia S14 and S15 with the SR20DET turbocharged four-cylinder are cars we see from the Japanese import pool. The SR20 is a robust engine when kept on quality oil at short intervals. Common areas to inspect include the turbocharger oil feed line condition and the crankcase ventilation system, both of which are age-related concerns on older SR20-equipped cars.

Where we start

Every Nissan performance car that comes to us new gets a full inspection: live data scan, cooling system check, differential and gearbox fluid assessment, and a visual inspection of the specific structural items relevant to that platform. From that we build a picture of what the car needs, in what order, at what cost. For more on import servicing specifically, see our Japanese imports page and transmissions page.
