![]() ![]() ![]() The Mazdaspeed3 was introduced for the 2007 model year - which, with 263 bhp (196 kW 267 PS) and 280 lb⋅ft (380 N⋅m) of torque - was the most powerful vehicle in its class. In 2006, the Mazdaspeed6 was released globally, featuring the most powerful piston engine ever produced by Mazda at 274 bhp (204 kW 278 PS) with an all-wheel drive layout. Mazda soon realized that these high performance models could be successful outside of North America and would make the next vehicles available worldwide. It featured an IHI single-scroll turbocharger producing 8.5 psi (0.6 bar) of boost to further increase power, from 142 bhp (106 kW 144 PS) to 178 bhp (133 kW 180 PS) and torque from 125 lb⋅ft (169 N⋅m) to 166 lb⋅ft (225 N⋅m). The Japanese market Mazdaspeed Familia utilized a naturally aspirated FS-ZE 2.0L engine with higher compression and a revised camshafts to produce 173 hp (129 kW) at 6800 rpm.Ī year after, in 2004, another Mazdaspeed model was offered: the Mazdaspeed MX-5 Miata, initially released in the North American market, followed by the Australian and Japanese markets. Some modifications included new front air dam and a new spoiler. It was only released to the North American market as a performance upgrade to the Protegé MP3 and offered more power - from the MP3's 140 bhp (104 kW) to 170 bhp (127 kW) - by using a T25 Callaway-Garrett turbocharger and an intercooler. In 2003, Mazda debuted its first consumer-offered Mazdaspeed vehicle model, the 2003 Mazdaspeed Protegé. The second generation Mazdaspeed3 in Germany. It began offering performance-based versions of its vehicles to consumers in 2003. Mazda Motor Corporation assumed control of Mazdaspeed in 1999 as a tuning and performance parts operation within the company. After the FIA effectively outlawed the Wankel engine as well as Mercedes's Flat 12 engine the next year, the Mazdaspeed team raced one more year at Le Mans in a piston-powered car that came fourth, then turned away from professional racing and focused instead on enabling third-party competition of Mazda vehicles. In 1991, Mazdaspeed's 787B won at Le Mans, a feat no other Japanese team managed until Toyota did in 2018. Mazda brought the racing team to Hiroshima in 1983, where the name became Mazdaspeed. They competed in numerous events at home and abroad, and they were also competitive at the 24 Hours of Le Mans races in the early 1980s, with the 717, 727, and 737. Mazdaspeed began in 1967 as "Mazda Sports Corner", an independent racing team and tuning operation run by Takayoshi Ohashi, who also ran Mazda's Tokyo distributor. Top quality, exact tolerances, the best materials and machining processes, and the ability to survive the rigors or racing and get you in the winner's circle make ARP fasteners the #1 choice.The Mazda 787B, winner of the 1991 24 Hours of Le Mans. More winning teams use ARP fasteners than all others combined. ARP is the leader in fasteners for racing and high performance. Premium parallel ground washers and Hex nuts (10 each) are also included with each kit. ARP® studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat. Because ARP® studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly alignedsomething that wont happen with inferior quality head studs. It's important to note that lesser quality studs are not even centerless groundthe material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). This procedure involves about ten very slight cuts and results in an exceptionally straight part. Following heattreat, each stud is centerless ground to make it as close to perfectly concentric as possible. Then, each stud is precisely heat-treated to 200,000 psi. You should know that ARP® uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. That's why ARP® head studs are popular among leading Sport Compact/Import racers. Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. ![]()
