VIDEO: This OS Giken twin-cam is the most glorious sound you’ll hear all week

OS Giken TC24-B1Z S30 Fairlady Z

You know the OS Giken TC24: The 9,000rpm twin-cam head for Nissan‘s L-series motor costing somewhere in the realm of $30,000 and harder to find than Yeti dandruff (only 11 were built). Last year we saw a new version, the TC24-B1Z, at Nos2Days with a completely re-worked valvetrain, gear-driven timing and a new-and-improved 10,000rpm redline. Well now the mad scientists at OS Giken have dropped it in a car, and here’s what it sounds like. Hint: It’s like a million-angel chorus.

    Amazing, the beautiful header you can use in a straight 6, RHD car with the carbs on the other side.
