The Mazda K family is a 60° V6 automobile engine, ranging from a tiny 1.8 L for the Mazda MX-3 to 2.0, 2.3 (in the Mazda Millenia) to 2.5 (for the Mazda MX-6, Mazda 626, Mazda Millenia, and early Mazda MPV). All are short stroke DOHC engines and were designed to be as compact as possible for short-hood front-wheel drive applications.
K8
The 1.8 L (1845 cc) K8 is among the smallest production V6 engines ever. It was a DOHC 4-valve design with VRIS and a 75 mm bore and 69.6 mm stroke. It produced 130 hp in US trim (sometimes referred to as "K8-DE"), and 135 hp in Japanese trim (the "K8-ZE") on introduction in 1992 and 144 hp (108 kW) and 115 ft.lbf (157 Nm) at its best.
Applications:
KF
- 2.0 L KF - 1995 cc (78x69.6 mm) - The 2.0 L KF-ZE engine produced 159 hp (119 kW) and 132 ft.lbf (180 Nm).
Applications:
KJ-ZEM
The 2.3 L KJ-ZEM is one of Mazda's most technologically advanced engines. It employs the "Miller cycle" which uses a supercharger to decrease compression losses and increase power. It was used in the T-platform cars. The supercharger used is the twin-screw type with electronic boost control. Power output was 217 hp (162 kW) and 210 ft.lbf. The KJ-ZEM was on the Ward's 10 Best Engines list for 1995 through 1998.
Applications:
KL
The 2.5 L (2497 cc) KL family uses an 84.5 mm bore and 74.2 mm stroke. It includes the Japan-only KL-ZE, which produced 199 hp (149 kW) and 165 ft.lbf (224 Nm). Another variant, the KLD (sometimes called the KL03) was the worldwide version, with 164-170 hp in various applications. A Variable Resonance Induction System (VRIS) was used on all variants, optimizing torque production over the entire rev band.
