RX7 4 Rotor Crazy
First time starting of a 4 rotor RX7, sounds insane
Handbuilt 4-Rotor Engine
This was a project that took about five years of weekends to put together. There was a lot of trial and error as jury-rigged parts were improvised and revised, leaks were identified and plugged, and byzantine electrical diagrams were decoded. It still does not run smoothly, as there likely is a problem with the intake system that has prevented smooth timing at idle. But she runs!
lots of people wanted to know where the E-shaft came from: it was custom ordered from a shop in New Zealand.
RE Amemiya Super Greddy 7 RE20B RX-7 FD3S
This RE Amemiya Super Greddy 7 RE20B was built for the annual Tokyo Auto Salon. This exquisite machine is packed with RE Amemiya's tuning knowledge and is setup for the street.
The intent of the vehicle is of course, running the Wangan highway. The machine was designed to easily reach high speeds and provide unmatched stability at 300km/h. This makes 300km/h seem like leisurely cruise.
The three rotor 20B engine was removed from a Mazda Cosmo. It is fairly easy for RE Amemiya to build a 300km/h engine, and it can be done with a 13B. Then why choose a 20B? The 13B is notoriously known to have a short life span, especially after it has been modified. Also, it lacks the low end torque, and it does not hold the power to leisurely reach, and cruise at 300km/h like the 20B.
Therefore, the 20B was chosen, and the low end torque demise was solved. But even though it's a rotary engine, doesn't mean that it is a easy swap. The weight distribution of the well balanced FD becomes thrown off. The 20B had to be offset 10cm to the rear and 6cm to the front in reference to the 13B. Also, the body, subframe, and the propeller shaft all need fabrication.
The exterior was dressed up with the RE Amemiya 2006 model Aero kit. It consists of a Porsche 997 front headlights, and the rotary themed rear bumper. The sides consist of super wide fenders to accentuate the whole look.
The vehicle was completed just in time for the first ever Pre Tokyo Auto Salon event held in the United States. The vehicle then will be shipped off in time for the real 2006 Tokyo Auto Salon event in Tokyo.
