My mazda Rx7, has a 12a peripheral port motor, with a modified nikki carb (the carb it originally come with) It still needs a bit of tuning, its a little bit lean at idle and on the primary circuit, so Ill get that sorted in the next few days, got a bit more power than the motor when it was just extend ported! I will eventually put an IDA on it but will run it like this first at the drags and see what we can get out of it!
Montaje del Motor Renesis - Mazda RX-8 - NO REBUILD
Proceso de remontaje del motor Renesis de un Mazda RX-8. NO ES UN REBUILD
de Motor puesto que no se han cambiado ninguna junta de estanqueidad,
sellos de aceite o sellos de motor. Se ha limpiado todas las piezas y se
han reutilizado, con el propósito de practicar el montaje del motor y
almacenarlo de una manera mas compacta para en un futuro rehacerlo con
piezas destinadas a su uso en competición.

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.

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.

1978 RX7 with a 12app on a nikki carb at motueka drags
This was my first run out for the season, the track was pretty slippery but
ran a 14.025 at 99.67mph, The engine is a 12a perpheral port which is
running a nikki 4 barrel which is the original carb the car came out with.
Not sure of the details on the other car but it ran a 17.614 @ 88.86mph
This was in Motueka Nelosn New Zealand.
The Mazda Rotary Engine Part 1
Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the
Rotary engine works with comparisons to the Piston Engine. Also shows the
Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or
110S). Originates from the late 60's.

Testing the home made wotbox(flatshift/launch control) on rx7
Just finished my home made wotbox, I have used a megasquirt 1 v2.2 and
used two outputs to drive a couple of relays which are in series with the
positive side of the coil, one of them has an earth to the clutch switch so
when the clutch is out it keeps the contacts closed on the relay, when you
put the clutch in it disconnects the earth and the ecu takes control at
whatever limit you set it too, in this video its 3500rpm, the second
solenoid is for an overall rpm limiter, also using the shift light
function of the ecu. The car is a 1978 rx7 with a 12a peripheral port
engine with a nikki carb, Hopefully this will make flatshifting and
My 12app RX7 on the dyno 166rwhp on a nikki carb
This is my 1978 rx7 series 1 on Top Speeds Dyno in Richmond Nelson NZ, It
has a 12a peripheral port engine with the factory nikki carburator
(modified a little) as the induction, When I drove it into top speed it was
making 132rwhp and now it has 166rwhp and 153ft lbs torque so Im pretty
happy with as these engines made about 87rwhp out of the factory, I will
eventually put a 50mm injection perfection setup on it and it should gain
alot more! But for now Ill put it on the strip like this and see how it
goes, When the engine was extend port it was running consistant 14.4
seconds on the 1/4 and had around 110rwhp so it should go alot better now!
