Back in the early days of Club4AG, parts for the
AE86 was difficult to come by. If you wanted some cool parts, you had to look to the other side of the pacific,
Japan not
China. One of the big things at the time was doing
20 valve swaps. The only down side was a proper header or lack of. But Moto from Club4AG contracted Techno Spirits boss Kumakura san to a make couple headers for the left hand drive cars. I forget how many went into circulation but I do remember 16v and 20v versions being made.
