Office Tomaitaku’s 1974 S30 powered by the a OS Giken TC24-B1engine.
A little history on the TC24 head:
In 1975, OS Giken made it’s memorable entry into the racing world with the its unparalleled Four Valve DOHC TC16-MAII/TC24-B1 engine and firmly established itself as one Japan’s most innovative race engineering companies.
There were only about 20 or so (maybe even less) of these heads made and they retailed for about $15,000 US 15 years ago. NUTS!
