included the use of three piston rings instead of five, piston oil squirters, and a spin-on oil filter instead of a paper cartridge type. In Australia and some other parts of the world, the SD33-engined Patrols were revised to standard 12-volt electronics. To accommodate the turbodiesel's extra power, these models featured a larger clutch (270 versus 240 mm) and larger oil cooler (five rows versus three) than the naturally aspirated version. These were the last Patrols to carry the Datsun brand; in line with the rest of the Nissan lineup, the Patrol lost its Datsun branding in 1984 in most markets. Spanish production Nissan acquired a 35.85% stake in Motor Ibérica in 1980, which was increased to 54.68% in 1982. In early 1983, the first Spanish-made Nissan Patrol left the plant in Zona Franca, near Barcelona. The first year's production, planned to be 4,000 to 5000 cars, was earmarked for Spain and Portugal. Exports were to follow during 1984. Nissan Ibérica-built Patrols originally received a Spanish-made Perkins MD27 four-cylinder diesel engine and Spanish transmission to meet local content regulations. Later on, this was replaced by the A428, which evolved into the A428T and then the A428II. Later yet, the RD28 and the RD28T were added to Spanish-made cars. 260 (1986–1993) The 260 series was a facelifted version of the Spanish-built 160 (easily spotted by the rectangular headlamps) sold in Europe and available in SWB and LWB with L28, SD33, RD28 and RD28T engines. The SD-engined version, at least in the UK market, had a 24-volt electrical system. Nissan helped Nissan Ibérica amortize plant investments. The 260 Patrol later received a facelift with a new grille similar to that of the Y60 series which succeeded this generation elsewhere. Spanish production continued until 1994 for export and until 2002 for the Spanish domestic market. Fourth generation (Y60; 1987) The Y60 was radically different mechanically from its predecessors, as it was the first Patrol with coil-spring suspension, increasing comfort and improving rough-ground handling. All Y60 Patrols had a three-link live axle suspension set-up at the front, with all wagons (SWB, LWB, and SWB LW) adopting a five-link set-up at the rear. The utility model was available with both a leaf-spring rear axle, and from 1994 onwards, a choice of the same coil-spring rear axle as the wagons. Sway bars were included on both front and rear coil-spring live axles. Power steering was standard.
