Maruha Race Cams · NA8 / NB1 Miata 1.8L Non-VVT
Maruha's full-race camshaft set for the 1.8L non-VVT engine. Larger duration and lift than the F Cam — designed for the driver who wants a more aggressive, track-focused power delivery. Still street-capable, but the power band shifts higher and the character becomes more purposeful. Maruha's recommendation for NA8 and NB1 builds running solid lifters and a performance exhaust.
Specifications:
Higher duration and lift than Maruha F Cams — more aggressive profile for track-biased builds
Requires Maruha Solid Lifters and Cap Shims (sold separately) — not compatible with OEM HLA
Pairs with Maruha adjustable cam gears for full timing optimisation
Sold as a set (intake + exhaust)
Fitment: NA8 1994–1997 · NB1 1998–2000 · 1.8L BP-ZE Non-VVT engine only.
Made in Japan. Authorized Maruha import by Chikara Motorsports — North America's only official Maruha dealer.
