In a further effort to keep the S30 models sporting in the face of increasingly stringent U.S. emission and safety requirements, engine size was again increased, this time to 2.8 liters. The L26 engine was bored out to create the L28, and a Bosch L-Jetronic fuel injection system was added. Canadian versions were uniquely equipped without the anti-smog components mandatory in the States. The model code is HS30, the same as for the original 240Z. The 1975 and 1976 models continued to be fitted with the U.S. federally-required impact absorbing bumpers that had been introduced for the mid-1974 model year of the 260Z. These bumpers were smooth surfaced, and blended into smooth black rubber extensions as they met the body of the car. The 1977 and 1978 models received bumpers with recessed channels added that blended into corrugated- or accordion-style black rubber extension trim. Also new for the 1977 model year, 280Zs no longer received the full-size spare tire, and instead had a "space saver" spare and a larger fuel tank. This resulted in a raised rear deck area made of fiberboard, reducing cargo space. In late 1976 and for most 1977–78 models, an optional five-speed manual transmission was available alongside the four-speed manual and the three-speed automatic options. It included a "5-speed" emblem on the left bottom edge of the rear hatch. For 1977 there was also an update from the charcoal painted hubcap style (with a chrome Z floating in the amber center emblems) to a hubcap that resembled an alloy wheel, bearing a center cap with a chrome Z floating in a black circle. In 1977 and 1978 respectively, Datsun offered two special edition models. The "Zap" edition was offered in 1977 as a "special decor package". Zap cars were finished in "sunshine yellow" paint, and sported black stripes down the center and sides, with yellow, red, and orange chevrons at the front ends of the stripes. An estimated 1,000 "Zap Z" cars were offered in 1977. The "Zap Z" model was also used as the pace car in the 1977 Long Beach Grand Prix. The Black Pearl edition (produced in 1978) came with
