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.

MAZDA RX7 Rotary Engine, How It Works
MAZDA RX7 Rotary Engine, How It Works
The MAZDA RX7 rotary or Wankel engine is a marvel of engineering. It has
won more races than any other vehicle in its class. Rotary engines develop
a great deal of power for their weight (power to weight ratio). They're
also able to develop high RPM bursts like no other internal combustion
engine. Learn the details of it operation, how the rotor transfers power to
the output shaft, what it the stationary gear set, what is the rotor to
output shaft ration and relationship. Get all the specifics on the rotary
engine's operation here in this video.
Presented using advanced software CG animation technology to help you
understand. Part of our Automotive Technology Rotary Wankel engines and
MAZDA RX7-RX8 series shown here on this channel. Enjoy...

Mercedes S-Class Coupe Concept INTERIOR
The white instrument panel exudes sensual clarity. Its curved shape is
reminiscent of a whale fluke just before it re-enters the water. Like the
entire interior it is dominated by flowing lines: the upper and lower wave
create a clear structure.
The upper section of the instrument panel seems to float sensually in front
of the dashboard as a so-called top layer. The instrument panel seamlessly
transitions into the doors in a wrap-around design. The wavelike motion
continues in the door panels.
The ventilation nozzles, which among other places are housed as a
four-piece cluster in the centre of the instrument panel, have a futuristic
and highly detailed design: fins that route the air stream surround an
oblong hole. The ventilation nozzles are designed to add contrasts and are
made of a mix of white aluminium with a ceramics-like appearance and
brushed and polished aluminium.
The aluminium control elements have a functional and clean design, and
provide an exciting contrast to the organic and avant-garde shapes that
On top of the free-form surface under a reduced hood are the 30.7-cm
(12.3-inch) screens familiar from the new S-Class. They have an aspect
ratio of 8:3. In the Concept S-Class Coupé the fully glazed colour
displays are even slimmer and seem to float even more freely. As high-tech
elements they offer an exciting contrast to the sensual landscape of the
instrument panel. The colour scheme of the displays is bluish and
consequently sporty and modern.
A touch screen showing four world clocks is located on the centre console.
The driver can choose which clocks to display: To do so, the driver first
scrolls on a globe in the display and selects a time zone before a
drop-down menu offers the corresponding city selections. The world clock
concept was designed and implemented by designers and engineers at the
Mercedes-Benz Advanced Design Center in Palo Alto, California, USA.
The central command unit on the centre console looks like a shiny jewel.
Its extremely high-quality "black diamond" surface creates depth of field.
The "black diamond" method uses the chemical CVD (chemical vapour
deposition) gas phase process to deposit a precious metal on a high-sheen
chrome surface at temperatures of 1000°C. The metal reacts with the
surface to form a layer that is highly scratch-resistant and has a high
The door panels of the Concept S-Class Coupé are made from aluminium.
Using computer algorithms delicate topographic lines were milled into the
metal and mimic the contours of the door-mounted control elements. This
creates an interesting light pattern with tiny sparkling highlights. For
this creation the designers drew their inspiration from rock formations in
Utah, USA. The progressive perforations of the loudspeakers were also
generated using algorithms and display some intelligent aesthetics of
Like the entire interior the seats have a highly dynamic and natural "flow
of lines" and continue the sculpted design of the shapes. The front seats
evoke associations of haute-couture tailoring because their sculpted shape
embodies sensual lines reminiscent of figurines in fashion design. In the
upper section of the seat the side bolsters envelope the occupant like a
collar. The vertical lines of the seats come courtesy of an array of
delicate piping. Piping on the side bolsters provides contrast and like the
perforation of the seat surfaces is a factor in the sporty-elegant
The choice of colours and materials plays with the extroverted contrasts of
anthracite and white as well as aluminium, and bolsters both the timeless
modernity and avant-garde nature of the design and the claim of the Concept
S-Class Coupé to ultimate exclusivity, high quality and perfection. In
this spirit the instrument panel and seats are made from supple calfskin.
The roofliner of the vehicle is made from hand-woven silk and consequently
underscores the exclusive character of the interior.

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 ].

2015 Audi TT & TTS Coupe - the design
A completely revised edition of a modern classic is ready to take center
stage: The Audi TT and Audi TTS will celebrate their world premieres at the
Geneva Motor Show (these vehicle are currently not available for sale. they
do not yet have a general type approval and are therefore not covered by
Directive 1999/94/EC.). The third generation of the compact sports car is
again captivating, with its emotional design and dynamic qualities. The new
Coupé is characterized by the use of innovative technologies in its engine
and in its control and display concept, including the Audi virtual cockpit.
