Nissan Develops 240Z DOHC Upgrade Decades After the Car's Retirement

Nismo's heritage program is going the whole nine yards with support for classic Nissans, offering everything from reproduction Skyline parts to factory restorations. Now it's gone a step further by designing an upgraded cylinder head for the L-series engine used from the Datsun 240Z to the Nissan 280ZX—more than four decades after the last L-series Z was built. Now that's what I call customer support.

The head debuted in a show car at Nismo Nostalgic 2Days 2024 after several years of development for Nismo's 40th anniversary, according to a post on NissanZClub.com. It upgrades the L-series inline-six used from the 1969 240Z to the 1983 280ZX, swapping its single overhead camshaft for dual cams. Nissan appropriately rechristened the engine to TLX, which I imagine stands for something like Twin-cam L-series eXperimental.
