BP-Z3
In 2001, Mazda introduced the BP-Z3 (also called BP-VE) variant of the BP engine with S-VT variable valve timing on the intake side, no more VICS, but there is Variable Tumble Control System (VTCS)in the BP-Z3. A similar looking but effectively very different set of valves that restrict the intake on cold start for emissions purposes, rather than the torque enhancing set of partial butterflies that increase velocity that are used in VICS. This was found in the 2001+ Miata. The Z family is an evolution of this engine.
In Australia, a turbocharged version of this engine produced 210 hp (157 kW) and 206 ft·lbf (280 N·m) in the Mazda MX-5 SP. The United States 2004-2005 Mazdaspeed MX-5 turbo is a BP-4W, not a BP-Z3.
