The cranckcase will be black ( alu for my engine), and reinforced like Nova or sirio.
The car is new: big air filter, 3 screws, black treatment and OS Reliability
Long stroke, new piston/sleeve, new cranckshaft, new conrod....
Full new in fact and especially designed for 16% nitro, but 25% also.
Os will produce new pipes and manifold for their engine for big performance...
Thank you for detail info...........
