Mazda Rx7 4-rotor race car. The making of a Defined Autoworks Beast. [Offical Video]
Never before seen footage showing the assembly/start-up of our custom
4-rotor. It is the first 4-rotor since the 787b to use triple spark plugs
per rotor. It is also the first since the 787 to feature telescoping intake
manifold. Custom made slide throttle body system. A world first however is
the use of a center main bearing and 4-piece eccentric shaft. Quick specs-
9.7:1 rotors, lightened and race clearanced. Race main bearings, and race
rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full
custom Peripheral Port in each rotor housing (defined auto), Aluminum side
housings for reduced weight. Needle roller bearing in the center housing.

Mazda RX-7 Spitting Huge Flames from Exhaust!
When I was driving back from an event, this turbocharged Mazda RX-7 FD3S passed me in a
tunnel. As you can see this tuned Mazda RX-7 FD3S was spitting some huge
flames from the Exhaust! Hate it or
love it, I really enjoyed it! :)

Would you drive a car built by a teenager in his parents driveway with no
safety features whatsoever? We did, and now we'll tell you why this ugly
RX7 is so brilliant.

At this speed, the tire patch that is touching the ground is LESS than the
width of your index finger across each tire.
Furthermore each patch is encountering dust and small sand-like particles
often. If you could keep the pace with this car and remain standing next
to it, you could reach over and push it away from you sideways with little
The announcer claims that an additional burst of oxygen in the fuel causes
a loss of control, but in all likelyhood, the wind just changes ever so
slightly, or began to blow (even lightly) and it was actually this that
nudged the cars nose off by just enough to start a flat spin.
Yes, a flat spin, like an airplane goes into!
No rudder on this vehicle, so no control!
Part 12: 13B Rotary Engine Rebuild - My 76 Mazda RX-5 Cosmo Restoration
Just as I promised last episode, it is finally time to build the engine!
Part 12 of my RX-5 Cosmo restoration covers the entire process of building
the 6 port 13B Mazda rotary engine. While this engine is a hybrid of GSL-SE
RX-7 and Cosmo parts, the process is the same for any rotary from a 12A to
a 13B NA, 13B turbo, 13B-REW or any
other variant of the 13B. This video shows the whole process of the engine
build, starting from measuring the rotors and covering everything else
including clearancing the side seals, assembling the rotors, complete
assembly the short block, setting the eccentric shaft end play and
installing the front cover and everything underneath it. It's probably the
most complete engine build video outside of what you can buy from the
vendors, and as such, is an hour long. After this one, I'm going back to
videos under 20 minutes. But for now, grab a beverage of your choice, sit
back, and enjoy.

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
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
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.
