Japanese model engine company O.S. is celebrating its 80th birthday this year, and they’ve released a special Gold Edition of its Speed-tuned 21XZ-B Spec.II engine to commemorate the milestone. The engine stands out from the original with a gold-anodized head and carburetor venturi, with the former emblazoned with black laser-etching. Only 100 Gold Edition engines will be sold, and can be purchased alone or with the O.S. T-2060SC exhaust pipe.
