Trim / Codes
The 1978 Nissan 280Z carried over the 2.8-liter L28E fuel-injected inline-six from the previous year, with only minor trim and equipment changes distinguishing it from the 1977 model. Both the two-seat coupe and 2+2 hatchback body styles remained available, paired with either a five-speed manual or three-speed automatic transmission. Common service considerations include aging L-Jetronic fuel injection components, timing chain tensioner wear, and rust in the sills, floor pans, and hatch area. Original rubber suspension bushings, brake hoses, and wiring insulation also typically require inspection or replacement on surviving examples.
