Rotary 20B turbo RX7 - Dyno & track
Built as an all-round event's car, Charles' Mazda RX-7 has undergone
serious chassis and engine changes including a Promaz Automotive
bridge-port 20B rotary engine. Boost
comes from a Garrett turbocharger while
the engine runs on methanol fuel controlled by a MicroTech LT16 computer
and LTC dash logger. Backed by a Jerico 5-speed dogbox, the clutch was
suffering on the Dyno
as the Promaz team got the car ready for Performance Car Mania. [

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! :)

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 ].

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.

On this episode of Ignition, Carlos Lago convinces Mazda to hand him the

involving driving experience and rotary engine that made the Mazda RX-7 so
unique, as well as its connection to the new generation of lightweight,
rear-wheel drive coupes like the Subaru BRZ and Scion FR-S.

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.
