Automotive Art: The OS Giken TC24-B1Z
Dovetailing nicely with my recent post about Nissan/Datsun L-series tuning lore, I came across this page featuring the OS Giken TC24-B1Z, a stroked 3.2l, 420-hp L-series topped with the legendary OS Giken DOHC, 24-valve cylinder head.
While it’s perhaps not the most romantic piece of machinery out there, the engine exudes a kind of precise beauty, sort of like an immensely powerful Seiko watch. The gear-driven cam arrangement, chosen for durability at the engine’s 10,000 (!) rpm redline, reinforces that analogy. Fuel injection is optional; the TC24-B1Z leaves the craftman’s bench with a lovely set of triple Webers, shown above.
The beauty comes at a price, though: Only nine have been built, and if the cylinder head alone is worth over $30,000, it’s not a stretch to imagine the whole package costs perilously close to 6 figures, if not more. Still, as the Bugatti Veyron of naturally-aspirated L-series engines, it’s a stunning sight to behold, and as a vintage Datsun owner, it’s affirming to know the platform is receiving such attention.
