KuRONEKO - hooh is a "huuuhh" kindda impress ar..sort of..
depends on overall condition etc etc.. fair price..not cheap and not too expensive.
if the car got mazdaspeed mode..i will said " whoooa"
Turbo
The ultimate 12A engine was the turbocharged and fuel injected engine used in the Japan-spec Cosmo, Luce, and RX-7. It featured "semi-direct injection" into both rotors at once, a technique that was much more successful than it would appear. A passive knock sensor was used to eliminate detonation, and later models featured a specially-designed "impact turbo" which was tweaked for the unique exhaust signature of the Wankel engine.
Output was 165 hp (123 kW) at 6000 RPM and 186 Nm (137 ft.lbf) at 4000 RPM.
Applications:
• 1982-1985 Mazda Cosmo
• 1982-1985 Mazda Luce
• 1984-1985 Mazda RX-7
12B
The improved 12B was quietly introduced in 1974. In the US it was the start of the single distributors engines.
NOTE: the previous 12A & 10A engines used the twin distributors.
Applications:
• 1974-1978 Mazda RX-2
• 1974-1978 Mazda RX-3
13B
The 13B is the most widely-produced engine. It was the basis for all future Mazda wankel engines, and was produced for almost 30 years. The 13B is no relation to the 13A. Instead, it is a lengthened version of the 12A, having 80 mm (3.1 in) thick rotors. It had the largest displacement yet at 654 cc, for a total of 1308 cc.
In the United States, the 13B was available from 1974 through 1978 and was then retired until the 1984 RX-7 GSL-SE. It was retired again in 1996 with the cancellation of the RX-7. The engine was continually used in Japan from 1972's Mazda Luce/RX-4 through 2002's RX-7.
AP
The 13B was designed with both high performance and low emissions in mind. Early vehicles using this engine used the AP name, which signified these two characteristics.
Applications:
• 1972-1980 Mazda Cosmo AP
• 1974-1977 Mazda Rotary Pickup
• 1975-1977 Mazda Roadpacer
• 1974-1978 Mazda RX-4
• 1975-1980 RX-5
13B-RESI
A tuned intake manifold was used in a Wankel engine for the first time with the 13B-RESI ("Rotary Engine Super Injection"). The so-called Dynamic Effect Intake featured a two-level intake box which derived a supercharger-like effect from the Helmholtz resonance of the opening and closing intake ports. The RESI engine also featured Bosch L-Jetronic fuel injection. Output was much improved at 135 hp (101 kW) and 133 ft•lbf (180 N•m).
Applications:
• 1984-1986 Mazda HB Luce
• 1984-1986 Mazda HB Cosmo
• 1984-1985 Mazda FB RX-7 GSL-SE
13B-DEI
Like the 12A-SPI, the second-generation RX-7 bowed with a variable-intake system. Dubbed DEI, the engine features both the 6PI and DEI systems, as well as four-injector electronic fuel injection. Total output is up to 146 hp (109 kW) at 6500 rpm and 138 ft•lbf (187 N•m) at 3500 rpm.
Applications:
• 1986-1988 Mazda RX-7, 146 hp (108 kW)
• 1989-1991 Mazda RX-7, 160 hp (119 kW)
13B-Turbo
The 13B-DEI was turbocharged in 1987. It features the newer four-injector fuel injection of the 6PI engine, but lacks that engine's eponymous variable intake system. The twin-scroll turbocharger is fed with a two-stage valve to reduce turbo lag. Output is way up at 185 hp (138 kW) at 6500 rpm and 183 ft•lbf (248 N•m) at 3500 rpm.
Applications:
• 1986-1991 Mazda HC Luce Turbo-II, 185 hp (138 kW)
• 1987-1988 Mazda FC RX-7 Turbo-II, 185 hp (138 kW)
• 1989-1991 Mazda FC RX-7 Turbo-II, 200 hp (147 kW)
13B-REW
A twin-turbocharged version of the 13B, the 13B-REW, became famous for its high output and low weight. The turbos were arranged sequentially using Hitachi HT-12 turbos, with the primary providing boost until 4,500 RPM, and the secondary coming online afterwards. Output eventually reached, and may have exceeded, Japan's "maximum" of 280 hp (208 kW) for the final upgrade or better known "series-8" version.
Applications:
• 1990-1995 Eunos Cosmo, 235 hp (176 kW)
• 1992-1995 Mazda RX-7, 255 hp (190 kW)
• 1996-1998 Mazda RX-7, 265 hp (197 kW)
• 1999-2002 Mazda RX-7, 280 hp (208 kW)
20B
In Le Mans racing, the first three-rotor engine used in the 757 was named the 13G. It was renamed 20B after Mazda's naming convention for the 767 in November of 1987.
The three-rotor 20B-REW was only used in the 1990-1995 Eunos Cosmo. It was the worlds first volume production twin-turbo setup featured in both 13B-REW & 20B-REW form. It displaced 1962 cc (three 654 cc rotors) and used .7 bar of turbo pressure to produce 300 hp (224 kW) and 300 ft.lbf (402 Nm). It was at the time the highest torque output engine of any Japanese vehicle manufacturer.
The 2006 ALMS GT Mazda RX-8 utilizes the 20B motor.
