Stage 2 turbo performance cams for Mazda B6 engines found in the MX-5 Miata. Suits upgraded 44-54mm turbo on B6T engines. Still maintains street drivability. Good improvement in mid-range to high rpm power compared to OEM cams. Great upgrade for cars used for spirited driving and track days. Kelford Cams recommend KVS12 valve spring upgrade.
