What its like owning a 3 Rotor 20B RX-7
I have one of the most amazing custom RX-7s in the world. I want to share
my experience of owning and driving such a unique car.
I explain where the engine came from, why its so special, and what it does
to a Mazda RX-7
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.

FEED RX-7 (Fujita Engineering FD3S)
Established on 1982, Fujita Engineering (or FEED) is now a 30-year old
company. Yet, their passion for rotary motorsports is as hot as ever. The
FD3S in this video was their new shop-car, built to become "the fastest
As a matter of fact, this car has already proven to be the fastest. On
December 2011, it won the class championship of the country's hottest
time-attack event "Tsukuba Super Battle".
3 months later, on March 2012 when this video was shot, once again Fujita
Engineering was at Tsukuba Circuit to verify what they had been developing
throughout the winter was correct. Under fine weather, brand new Advan
tires, and having the right driver, the car marked 57.511 sec at the attack
at end of the day - beating their own Super Battle record by 0.5 sec.
Looks like Fujita Engineering RX-7 is going to win the time-attack again
- Attack Driver: Nobuteru Taniguchi (particularly on this day)
- Tires: Advan A050 295/35R18
- Wheels: Advan Racing TC III 11.0J+30
- Remaining Devices, Air conditioner, audio equipment, catalyzer, H-pattern
- Honors: Winner of 2011 Tsukuba Super Battle / Street S-class (58.051 sec)

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.

This car made me a car guy. When it works it is pretty near perfect and if
you know what you are doing, it can run really well. Make sure you learn
how to drive and this car will reward you like anything. Akin in its day to
the exige now, it is awe inspiring and fun go-cart. Its styling is still
amazing and I still have notes all the time on my car asking to sell it -
even with faded paint. This car is about the spirit of driving for sure.
Cornering. Sweat on the back of my neck on the perfect apex with full on
power-on over-steer. telegraphic handling If you know what you are doing
350+ reliable HP is easily within reach...
The build quality was not great. You have to take care to upgrade/replace
key components. The finish was just not that of a super-car. If it were,
the car would be near-perfect.
To completely sum up the TT Rx7: PURE sports car experience, a lot of TLC.
It's rare to find a car this enjoyable, and if you take care of it it will
take care of you. I bought mine a little over a year ago with a reman
engine, and even though I've spent a ton on reliability parts and other
repairs, nothing makes me smile more than hitting the gas in this car. If
you got a little money, you're a real car guy and you don't mind learning a
little about the car you drive, don't pass up the Rx7.
From the moment I saw the RX-7 I wanted it. It is truly one of the most
beautiful designs to ever come out of Japan. I have owned this and the
Nissan Twin turbo 300. While the 300 is
overall a better "car", the RX-7 is really more of a true sports car. Good:
Styling, smooth engine, looks very expensive, interior well laid- out. Not
so good: If you are considering one, and are not planning on putting on an
aftermarket turbo, etc., BUY A WARRANTY.
I went through three orig equip turbos
but luckily had a warranty. You can buy a warranty on this ride for under
$2K, and you WILL be glad you did. Other bad: drinks premium fuel like a
freshman fraternity pledge at a beer keg. You WILL replace radio.
Styling, performance, uniqueness, ability to increase performance to
awesome levels if you want to spend the money.
Gas mileage, turbo reliability. While I
am a pretty slim guy, if you are a little big around the middle or a re a
big person in general you will find this car to be uncomfortable. Also, if
you have the choice, get the base model with the cloth upholstery - it
holds up a lot better than leather.
This car was the bomb. Great handleing, great performance, beautiful to
look at. I found this beauty at a little local dealer and $9000 later drove
off with the most powerful car I have ever owned. 215hp and suspension that
allowed me to take it around corners over 60 like they weren't even there.
Traded it for 99 Saab 93 SE convertable for my wife nine months later. Made
$3000. Still kicking myself for that one....
The 3rd generation Mazda's RX7 rightfully won Motor Trend's Car of the year
award when it was first released 10 years ago. Its combination of
acceleration, handling and styling made it the best sports car to ever come
from Japan and better than many cars that cost twice or even three times as
much, including Porsche. This car is a true sports car not just a sporty
car and it sacrifices many comforts for performance.
Rotary engine is light, compact and revs to the limit in a very smooth and
predictable manner. Handling is phenomenal. Braking is excellent. Good leg
Devoid of any cargo space. Harsh ride. Consumes premium fuel at an alarming
I bought this car because of its reputation. Since buying it, I've done
numerous things to it to improve reliability and performance, and every
minute has been a blast. This car still gets lots of looks, and can
outperform many faaaaar more expensive cars.
RWD, huge community and availability of modifications/parts.
Needs a Boost gauge from the
factory. Better quality factory parts...Intercooler, radiator, etc. Many parts
are not sufficient for hard driving. Standard dual oil coolers. More exotic
