The Zero F**ks Given RX7 - /TUNED
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.

The Series 3 (1984--1985) featured an updated lower front fascia. North
American models received a different instrument cluster (the NA S3 RX-7 is
the only rotary-engined car to not have a centrally mounted tachometer).
GSL package was continued into this series, but Mazda introduced the GSL-SE
sub-model. The GSL-SE had a fuel-injected 1.3 L 13B RE-EGI engine producing
135 hp (101 kW) and 135 lb·ft (183 N·m). GSL-SEs had much the same
options as the GSL (clutch-type rear LSD and rear disc brakes), but the
brake rotors were larger, allowing Mazda to use the more common lug nuts
(versus bolts), and a new bolt pattern of 4x114.3 (4x4.5"). Also, they had
upgraded suspension with stiffer springs and shocks. The external oil
cooler was reintroduced, after being dropped in the 1983 model-year for the
controversial "beehive" water-oil heat exchanger.
The 1984 RX-7 GSL has an estimated 29 highway miles per gallon (8.11 litres
per 100 km) /19 estimated city miles per gallon (12.37 l/100 km). According
to Mazda, its rotary engine, licensed by NSU-Wankel allowed the RX-7 GSL to
accelerate from 0 to 50 (80 km/h) in 6.3 seconds. Kelley Blue Book, in its
January--February 1984 issue, noted that a 1981 RX-7 GSL retained 93.4% of
its original sticker price.
1985 - Mazda released in Australia the RX7 Finale - this was the last of
the series and brought out in limited numbers. The Finale featured power
options and a brass plaque mentioning the number the car was as well as
"Last of a legend" on the plaque. The finale had special stickers and a
blacked out section between the window & rear hatch.
The handling and acceleration of the car were noted to be of a high caliber
for its day. This generation RX-7 had "live axle" 4-link rear suspension
with Watt's linkage, a 50/50 weight ratio, and weighed under 2500 lb (1100
kg). It was the lightest generation of RX-7 ever produced. 12A-powered
models accelerated from 0--60 mph in 9.2 s, and turned 0.779g (7.64 m/s²)
laterally on a skidpad. The 12A engine produced 100 hp (75 kW) at 6000 rpm,
allowing the car to reach speeds of over 120 miles per hour (190 km/h).
Because of the smoothness inherent in the Wankel rotary engine, little
vibration or harshness was experienced at high rpm, so a buzzer was fitted
to the tachometer to warn the driver when the 7000 rpm redline was
The 12A engine has a long thin shaped combustion chamber, having a large
surface area in relation to its volume. Therefore, combustion is cool,
giving few oxides of nitrogen. However, the combustion is also incomplete,
so there are large amounts of partly burned hydrocarbons and carbon
monoxide. The Exhaust is hot enough
for combustion of these to continue into the Exhaust. An engine driven pump supplies air into
the Exhaust to complete the burn of
these chemicals. This is done in the "thermal reactor" chamber where the Exhaust manifold would normally be on a
conventional engine. Under certain conditions the pump injects air into the
thermal reactor and at other times air is pumped through injectors into the
Exhaust ports. This fresh air is
needed for more efficient and cleaner burning of the air/fuel mixture.
Options and models varied from country to country. The gauge layout and
interior styling in the Series 3 was only changed for North American
versions. Additionally, North America was the only market to have offered
the first generation RX-7 with the fuel-injected 13B, model GSL-SE. A turbocharged (but non-intercooled) 12A
engine was available for the top-end model of Series 3 in Japan.
Sales were strong, with a total of 474,565 first generation cars produced;
377,878 were sold in the United States alone. In 2004, Sports Car
International named this car #7 on its list of Top Sports Cars of the
1970s. In 1983, the RX-7 would appear on Car and Driver magazine's Ten Best
list for the first time in 20 years

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.
