The ultimate street Naturally aspirated cams for SR16VE/SR20VE engines. Nissan N1 main lobe with 20V spec side lobes. Still maintains good street drivability and mild idle off-VVL. The 184-D VVL lobes open up top end power in the 5.5k-9k rpm range for track use or spirited driving. Must have basic intake and exhaust system upgrades. Kelford Cams recommend KVS10-BT valve spring kit. Primary lobe spec: Intake: 250°/10.2mm | Exhaust: 246°/8.3mm
