20B rotary RX-7 Spirit R: The Ultimate Street Mazda
Built by Promaz Automotive, we think it's hard to go past Steve's wicked Series 8 FD RX-7 if rotaries are your game. Limited to around 1500 unit's, the Spirit R was the last of the RX-7's and featured a lot of upgraded factory parts as well as a low 1100kg weight. Now powered by a lethal Promaz triple rotor 20B extend port rotary engine, power is aided by a Garrett GT42R turbo and MicroTech fuel system and transmitted through an Albins 5-speed gearbox and KAAZ rear end [ http://www.promaz.com.au ]. http://www.fullBoost.com.au Get your track gear! http://shop.fullBoost.com.au Follow us on social media @ Google+ https://plus.google.com/+fullBoost Facebook http://www.facebook.com/fullBoostcomau YouTube http://www.youtube.com/user/fullBoost...

Ckeck it out! https://youtu.be/n6CW-TtzrEw Skyline R34, The King of Streets! https://youtu.be/G8zQfoGW2x8 The Mazda RX-8 is a sports car that was manufactured by Mazda between 2003 and 2012. It was first shown in 2001 at the North American International Auto Show. It is the successor to the RX-7 and, like its predecessors in the RX range, it is powered by a Wankel engine. The RX-8 began North American sales in the 2004 model year. Mazda announced on August 23, 2011, that the RX-8 was to be discontinued citing the 2011 model as the last line of production. The RX-8 was removed from the European market in 2010 after the car failed to meet emissions standards. Without the volume sales from Europe coupled with rising Yen prices, Mazda could not justify the continued sale of the RX-8 in other markets.Mazda introduced rotary engine vehicles in the US in 1971, beginning with the R100 and eventually introducing the RX-2, RX-3, RX-4, RX-5, and three generations of the RX-7 sports car. However, due the lack of conveniences and user-friendliness, coupled with the high price tag and declining interest in sports cars and coupés at the time, Mazda decided to withdraw the RX-7 from most major markets except Japan. After 1995, Mazda suffered from a relatively undistinguished and ordinary product line in the US except for the MX-5 Miata. As popular interest in import tuning and performance cars resurged in the late-1990s due in part to various popular cultural influences, Japanese automakers waded back into the performance and sports car market in the US. In addition, Mazda endeavoured to rejuvenate itself around this time, partially with financial and management assistance from Ford, and successfully developed a new product line of high quality cars with desirable styling and superior driving dynamics compared to their competitors, beginning with the Mazda6 and followed by the Mazda3, paving the way for the arrival of Mazda's next-generation rotary sports car. The RX-8 combined two previous products (the internationally sold RX-7, and the Cosmo which was exclusive to Japan), with the exterior dimensions of the RX-8 to be slightly smaller than those of the Cosmo. Mazda chose not to install the 2.0 L three-rotor 20B-REW, which was discontinued in 1996 when the Cosmo ceased production. In Japan, sales were affected by the fact that the RX-8 did not comply with Japanese Government dimension regulations, and Japanese buyers were liable for yearly taxes for driving a larger car. The rotary engine had financial advantages to Japanese consumers in that the engine displacement remained below 1.5 litres, a significant determination when paying the Japanese annual road tax which kept the obligation affordable to most buyers, while having more power than the traditional inline engines.The Renesis engine – also 13B-MSP (Multi-Side Port) – which first appeared in production in the 2003 Mazda RX-8, is an evolution of the previous 13B. It was designed to reduce Exhaust emission and improve fuel economy, which were two of the most recurrent drawbacks of Wankel rotary engines. It is naturally aspirated, unlike its predecessors from the 13B range, and therefore slightly less powerful than Mazda RX-7's twin-turbocharged 13B-REW (255-280 hp). The Renesis design features two major changes from its predecessors. First, the Exhaust ports are not peripheral but are located on the side of the housing, which eliminates overlap and allows redesign of the intake port area. This produced noticeably more power thanks to an increased effective compression ratio; however, Mazda engineers discovered that when changing the Exhaust port to the side housing, a buildup of carbon in the Exhaust port would stop the engine from running. To remedy this, Mazda engineers added a water jacket passage into the side housing. Secondly, the rotors are sealed differently through the use of redesigned side seals, low-height apex seals and the addition of a second cut-off ring. Mazda engineers had originally used apex seals identical to the older design of seal. Mazda changed the apex seal design to reduce friction and push the new engine closer to its limits

Rotary 20B turbo RX7 - Dyno & track
Built as an all-round event's car, Charles' Mazda RX-7 has undergone serious chassis and engine changes including a Promaz Automotive bridge-port 20B rotary engine. Boost comes from a Garrett turbocharger while the engine runs on methanol fuel controlled by a MicroTech LT16 computer and LTC dash logger. Backed by a Jerico 5-speed dogbox, the clutch was suffering on the Dyno as the Promaz team got the car ready for Performance Car Mania.
