Question: The Mazda F platform was used in a sports car design in 1978 with which Engine?

full_context: Document 1: General Motors Rotary Combustion Engine: The General Motors Rotary Combustion Engine (GMRCE) is an internal combustion Wankel engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. In November 1970, GM paid $50 million for initial licenses to produce their version of the Wankel rotary engine, and GM President Ed Cole initially projected its release in three years. Chevrolet, with impetus from Pete Estes and John DeLorean, as well as Ed Cole worked on the Wankel. Bob Templin was the chief executive in charge of rotary-engine research at the GM Tech Center in Warren, Michigan, but Ed Cole would leave his office in Detroit twice a week for the trip to Warren, taking charge of the program. The engine was initially targeted for an October 1973 introduction as a 1974 Chevrolet Vega option.
Document 2: Mazda GTP: The Mazda GTP is an IMSA GTP car that was built by Pierre Honegger in 1981. Based on a Mazda RX-7, the car initially competed in the GTX category as the Mazda RX-7 GTP, before it was rebuilt for the IMSA GTP category in 1983. Throughout its career, the car used a Mazda 13B Wankel rotary engine, similar to that used in the production RX-7s. Although the rotary-engined sports prototypes generally had a reputation of being very reliable, the Mazda GTP frequently failed to finish races, and was never able to better the eighth place achieved at the 1983 24 Hours of Daytona. In 1986, one car was purchased by Erie Scientific Racing, and rebuilt to become the Badger BB. This car was no more successful or reliable than its predecessor, and was last used in 1989, by which point it was owned by Jack Engelhardt. The other car, meanwhile, was rebuilt by Honegger into the Denali Speedcar, which was used with moderate success in 1986 and 1987.
Document 3: Mazda RX-8 Hydrogen RE: The Mazda RX-8 Hydrogen RE is a 2003 bi-fuel version of the RX-8 sports car, in which the twin-rotor wankel rotary engine is configured to run on either hydrogen or gasoline. This is the fifth Mazda vehicle to be fitted with a hydrogen wankel rotary engine. The hydrogen tank, with a capacity of 110 liters at 350 bar stores up to 2.4 kilograms of hydrogen and is fitted in addition to the 61 liter gasoline tank. In 2005, Mazda obtained street approval for this vehicle. The following year, the first vehicles were leased to customers (Idemitsu and Iwatani). In November 2007, Mazda announced the delivery of 30 RX-8 HRE to the Norwegian hydrogen project Hynor.
Document 4: Mazda Roadpacer AP: The Mazda Roadpacer AP (Anti Pollution) is a full-size sedan that was sold by Mazda in Japan between 1975 and 1977, although the last car was not sold until 1979. It was based on the Australian Holden HJ and HX series Premier. Premiers were shipped to Japan without engines, and Mazda fitted a 1.3-liter "13B" Wankel engine into the bay. Although the engine produced 100 kW and 138 Nm of torque, the Roadpacer performed rather poorly as it weighed 1575 kg . The Roadpacer was introduced to compete with large Japanese flagship sedans Toyota Century, Nissan President, Isuzu Statesman de Ville, and the Mitsubishi Debonair.
Document 5: Mazda F platform: The Mazda F platform is an automobile platform for rear wheel drive sports cars. It was the basis for three generations of the Mazda RX-7.
Document 6: RE Amemiya: RE Amemiya Car Co Ltd (有限会社RE雨宮自動車 , Yūgen Kaisha Āru-ī Amemiya Jidōsha ) is an automotive tuning company from Chiba, Chiba Prefecture, Japan founded by Isami Amemiya. Amemiya has made a name for himself tuning rotary engines since 1974 and has become a pioneer in tuning rotary-powered Mazdas. Thirty years later, first on the street and later in the Super GT series, Amemiya has left its mark in the tuning and motorsports worlds for rotaries.
Document 7: Mazda RX-7: The Mazda RX-7 is a sports car that was assembled and produced by the Japanese automaker Mazda from 1978 to 2002. The first RX-7 featured a 1146 cc twin-rotor Wankel rotary engine and a front-midship, rear-wheel drive layout. The RX-7 replaced the RX-3, with both models sold in Japan as the Mazda Savanna.
Document 8: Wankel engine: The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. In contrast to the more common reciprocating piston designs, the Wankel engine delivers advantages of simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio primarily due to the fact that it produces three power pulses per rotor revolution compared to one per revolution in a two-stroke piston engine and one per two revolutions in a four-stroke piston engine (although at the actual output shaft, there is only one power pulse per revolution, since the output shaft spins three times as fast as the actual rotor does, as can be seen in the animation below, making it roughly equivalent to a 2-stroke engine of the same displacement; this is also why the displacement only measures one face of the rotor, since only one face is working for each output shaft revolution). The engine is commonly referred to as a rotary engine, although this name also applies to other completely different designs, primarily aircraft engines with their cylinders arranged in a circular fashion around the crankshaft. All parts rotate consistently in one direction, as opposed to the common reciprocating piston engine, which has pistons violently changing direction. The four-stage cycle of intake, compression, ignition, and exhaust occur each revolution at each of the three rotor tips moving inside the oval-like epitrochoid-shaped housing, enabling the three power pulses per rotor revolution. The rotor is similar in shape to a Reuleaux triangle with sides that are somewhat flatter.
Document 9: Mazda F engine: The F engine family from Mazda is a mid-sized inline-four piston engine with iron block, alloy head and belt-driven SOHC and DOHC configurations. Introduced in 1983 as the 1.6 litre F6, this engine was found in the Mazda B-Series truck and Mazda G platform models such as Mazda 626/Capella as well as many other models internationally including Mazda Bongo and Ford Freda clone, Mazda B-series based Ford Courier, Mazda 929 HC and the GD platform-based Ford Probe
Document 10: Mazda Persona: The Mazda Persona is a mid-sized, front-wheel drive, four-door hardtop sedan produced by Mazda in Japan from November 1988 to 1992, and sold both within its main range and under its upscale Eunos brand, as the Eunos 300. It used Mazda's MA platform and was replaced by the ɛ̃fini MS-8 in March 1993.
Document 11: Mazda RX-9: The Mazda RX-9 is a sports car produced by the Japanese automaker Mazda scheduled for release in 2020. "Holiday Auto", a Japanese magazine, reported it will be previewed at the 2017 Tokyo Auto Show, and the final production model will be featured at the same event in 2019. The car will be released in January 2020, to coincide with Mazda's 100th anniversary, and will be initially priced at eight million yen (US$(8000000/ 105.944781 )round0 in 2015). It is believed it will showcase the return of the Wankel rotary engine, but CEO Masamichi Kogai said Mazda will not launch another rotary engine. In the middle of the September 2017, Mazda has filed a patent application for an engine that uses two conventional turbochargers and an electric supercharger. The engine looks compact, can replace the rotary engine and possibly be included in RX-9 production.
Document 12: Mazda Sentia: The Mazda Sentia is a large rear wheel drive luxury car that was sold by Mazda in Japan from 1991 to 1999 over two generations. It replaced the Mazda Luce nameplate on the Mazda H platform, and continued the tradition of being Mazda's largest flagship sedan, which had been in production since the late 1960s. The name "sentia" is derived from the Latin word ""sentir"", meaning to sense, feel or hear.
Document 13: Mazda Grand Familia: The Mazda Grand Familia is an automobile which was produced by Mazda in Japan from 1971 to 1978. It was sold as the Mazda 808 in some export markets including Asia, Australia, and New Zealand, and as the Mazda 818 in many others. The body style configurations offered were a two-door coupé, a four-door sedan, and a five-door station wagon. The Grand Familia offered only inline four cylinder engines. The largely identical rotary-powered versions were marketed as the Mazda Savanna in Japan, with export markets taking this model as the Mazda RX-3.
Document 14: Mazda Familia: The Mazda Familia, also marketed prominently as the Mazda 323 and Mazda Protegé, was a small family car that was manufactured by Mazda between 1963 and 2003. The Familia line was replaced by the Mazda3/Axela for 2004.
