Mazda B engine

B1 B1 - (68.0x78.4 mm) - came only as a SOHC 8-valve. It was available in the 1987–1989 Mazda 121 and later model Kia Sephia in European and Asian markets. A fuel-injected variant was used in select European market 1991–1995 Mazda 121s ==1.3 liters==

BJ The BJ engine (78.0x67.5 mm) was a DOHC 16-valve engine, used only in the Japanese market Ford Festiva GT, GT-X, and GT-A models (1986.10–1993.01, GT-A from March 1991). It generates at 7000 rpm and is equipped with Mazda's "EGi" single-point fuel injection. It is a short-stroke version of the B5/B6 engines. B3 B3 – (71.0×83.6 mm). It was available in SOHC variants and was found in the Kia-built 1988–1993 Ford Festiva, the 1987–1989 Mazda Familia and its derivatives, as well as the Mazda 121 (also known as Autozam Revue) in versions, and the 1987–1989 Ford Laser, and 1994–1997 Ford Aspire. Later variants were used in the Mazda Demio subcompact until 2002.

B5 8-valve SOHC B5 - (78.0x78.4 mm) - The SOHC 8-valve B5 upped the displacement to 1.5 liters and was found in the 1987–1989 Mazda Familia and the 1987–1989 Ford Laser. It was also fitted to the Mazda Étude coupé and fifth-generation BF-series Familia Wagon, as it continued in production until 1994 along the new BG. 16-valve SOHC There was also a 16-valve, SOHC B5-MI version of the B5, usually fitted with single-point fuel injection ("EGi"). This engine was mainly used in the Japanese domestic market. The B5-ME, equipped with electronic fuel injection, was used by Kia for several of their cars as well as in the Mazda Demio. 16-valve DOHC B5D - (78.0x78.4 mm) - A Japanese-only variant of the B5 with fuel injection and revised head/intake system. Found in the 1989–1994 BG Familia and Ford Laser S. Power output is at 6,500 rpm and at 5,500 rpm. This was also installed in the Japanese market "Ford Laser"-badged versions of the Familia. ==1.6 liters==

B6 B6 — (78.0x83.6 mm) — This was a bored-out version of the B3. The 16-valve SOHC B6 was found in the 1985–1989 and 1990–1994 Mazda 323, 1991–1993 Mazda MX-3 the 1987–1990 Mercury Tracer, and the 1985–1990 Ford Laser. The 16-valve DOHC B6 was also found in the 1994–1998 Ford Laser KJ/KL, 1997–2004 Kia Sephia, Kia Shuma, 2000–2004 Kia Spectra and 2000–2005 Kia Rio (for export markets). In Japan, the United Kingdom, and Australia a fuel-injected version called the B6F was available. In Europe, the B6 also came in a 16-valve SOHC version, mostly found in the Mazda 323 BG and 323F BG models from 1989 to 1994. This engine was the same 1.6 liter fuel-injected and 88 hp. Kia's version of the B6 (16-valve DOHC) had a marginally shorter stroke (at 83.4 mm), for a total displacement of 1,594 cc. This engine was used in the Rio, Sephia II, and Shuma. ;8-valve SOHC • 1985–1989 and 1990–1994 Mazda 323 • 1994–1996 Kia Sephia (for export markets only: DE, USA) • 1987–1990 Mercury Tracer • 1985–1990 Ford Laser KC/KE 323 ;16-valve SOHC • 1991–1993 Mazda MX-3 • 1989–1994 Mazda 323 BG • 1989–1994 Mazda 323F BG/Mazda Astina BG • 1989–1994 Ford Laser KF/KH ;16-valve DOHC • 1989–1993 Mazda Miata • 1993–1999 Mazda Xedos 6 • 2000–2005 Kia Rio (for export markets only) • 1997–2003 Mazda Familia/ Mazda Etude (South Africa) • 1991–1994 Mercury Capri (USDM) B6-2E B6-2E - (78.0x83.6 mm), also known as B6-ME - This was a variant of the B6-E with a SOHC, 16-valve cylinder head. B6T B6T - (78.0x83.6 mm) - The ubiquitous turbocharged, fuel-injected and intercooled 16-valve DOHC B6, released in 1985 and used in numerous models worldwide including the 1985–1989 Mazda Familia BFMR/BFMP (turbo), 1985–1989 Ford Laser TX3 turbo, and 1991–1994 Mercury Capri XR2. This engine was most commonly found mated to a 4WD drivetrain although FWD models were also available. Power and torque outputs varied across markets due to emission and fuel standards. The B6T available in North America came with and . The Japanese version was slightly more powerful, producing and due to better intake manifold design and its ability to run 100 octane fuel. For the special rally homologation BFMR Familia GT-Ae model released in 1987, power and torque were raised to and respectively through the use of a slightly different turbocharger; engine internals remained otherwise identical. B6D B6D - (78.0x83.6 mm) - The same strengthened and fuel-injected 16-valve DOHC B6 but with higher compression, no turbo, and the first Mazda engine to feature Variable Inertia Charge System (VICS). Most commonly found in the 1985–1988 Japanese market Familias, Études and Lasers, this engine was updated in 1989 with revised compression, heads and intake system (in a similar vein to the B5 DOHC) for the 1989–1991 Familia and Laser, then further refined for the 1991–1994 Mercury Capri and 1994 to 1996, second Generation Mazda MX-3 RS. The third-generation B6D features an alloy cam cover, a VLIM (VICS) intake, had a 9:1 compression ratio and produced 107 hp (79 kW). • 1989–91 Mazda Familia • 1991–1994 Mercury Capri • 1994–96 Mazda MX-3 • 1994–1996 Ford Laser • 1985–1988 Ford Laser, Études, Mazda Familia • 1995–1997 Kia Sephia B6ZE(RS) B6ZE(RS) - (78x83.6 mm) - Developed for the Mazda MX-5/Miata (1989–05) and Mazda Familia sedan GS/LS Full Time 4WD (JP only, 1994–1998). The engine uses a DOHC 16-valve alloy head with a lightened crankshaft and flywheel to allow a 7,200 rpm redline. An aluminum sump with cooling fins is an unusual feature of this engine. The US and European version (1990–1993) had a 9.4:1 compression ratio and produced at 6,500 rpm, and of torque at 5,500 rpm. The later European version (1994–1997) produced at 6,500 rpm, and at 5,500 rpm. It was then updated to at 6,500 rpm and at 5,000 rpm for the models from 1998 to 2005. The Japanese version of the engine also had a 9.4:1 compression ratio and produced at 6,500 rpm and at 5,500 rpm. After 1998 the power was increased to at 6,500 rpm and at 5,000 rpm. ==1.7 liter diesel==

PN27 PN27 - (78x90 mm) The PN27 is a 1720cc B6 based diesel motor used in the 1986–1989 Mazda Familia. PN46 PN46 - (78x90 mm) The PN46 is a 1720cc B6 based diesel motor used in the 1987–1989 Mazda Familia ==1.8 liters==

B8 The B8 (sometimes "BP") is not just a bored and stroked B6. Rather, it uses a new block with widened cylinder spacing. The bore is 83 mm and the stroke is 85 mm. This SOHC engine was used in various Australian Mazda 323s, the American 1990–1994 Mazda Protegé, and in Canadian variants of the 323 hatchback. It came with four valves per cylinder (B8-ME or BP-ME). It features hydraulic lash adjusters, a belt-driven cam, an 8.9:1 compression ratio, a 6,000 rpm redline, and multi-port fuel injection. Power outputs are: • , 111 lb-ft (U.S./Canadian market) The Mazdaspeed turbo engine has no VICS, but does have VTCS which is often mistaken to be related to VICS. Applications: • 1998–2000 Mazda MX-5/Roadster/Miata • 2004–2005 Mazdaspeed MX-5 BP-Z3 In 2001, Mazda introduced the still BP-Z3 (also called BP-VE) variant of the BP engine. It features 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 and in the Mazda MX-5 SP. ==See also==
