cam gears are much the same, if you have a clear belt cover maybe get ones that look good?
i have sard 700's on mine but i wanna go to 330-350rwkw, so maybe 550cc/min
if you get z32 afms(80mm), you have to replace your apexi suction kit and the connector plugs
i went with rb20/25 afms(80mm), as they work with PFC, use the same plugs as rb26, and i just bought the apexi 80mm suction kit, although the rb20/25 afms dont have the high end resolution the z32's have
