Manually cranking a freshly built 12A peripheral port engine. The engine is built with 3 window bearings, is doweled and has a shimmed oil pressure regulator. Ultimately it will run EFI and be turbocharged. Plugs are installed (listen to those pops!)
How to rebuild a Rotary Bridge Port engine ~ fullBOOST tech files
FullBoost Tech Files, Ep 1 ~ Rebuild
and Bridgeport of a 13B rotary engine @ Mr Parts.
We have started with a stripped down 1984 Mazda RX7 13BT engine, and will
run through the steps involved in bridge porting the engine, then assembly,
to the start up in its new home, a 1972 Mazda 808 (RX3). [

Part 33: Turbine Heat Shield Fab & Intake Manifold Cleaning - My 76 Mazda RX-5 Cosmo Restoration
Part 33 of my '76 Mazda Cosmo restoration deals with what I would consider
to be two important, though miscellaneous, tasks. While waiting for the Intercooler parts to arrive I
tackled what I thought would be a quick and easy job; building a turbine
heat shield. I won't admit how long it took but suffice it to say that the
Intercooler supplies not only
did arrive during the heat shield build, but were also packed away under
the car and began to grow shop dust. Regardless of the time it took I must
say I'm quite happy with the heat shield as I've seen very few like it. So
many of the turbine heat shields on the market are nothing but a bit of
bent sheet metal and a mounting bracket. At that point I decided I may as
well deal with another small job so I took the time to remove excess OEM
equipment from the throttle body and eliminate all the unnecessary vacuum
nipples on the upper intake manifold. Included in this episode: turbo turbine heat shield fabrication, turbo assembly/disassembly, template making,
stainless steel sheet metal cutting/drilling/grinding/bending, TIG welding
stainless, OEM intake manifold extra nipple removal, TIG welding aluminium,
FD throttle body simplification
Part 34: Water To Air Intercooler Installation, Part 1 - My 76 Mazda RX-5 Cosmo Restoration
It's time for part 34 of my '76 Mazda RX-5 Cosmo restoration. This time,
I'm installing the water to air Intercooler. I've installed and
fabricated plenty of air to air Intercoolers in my time but never a
water to air unit. I chose to use water to air on the Cosmo because it
meant that I could keep the piping as short as possible for the best Boost response and because of the
limited amount of room to run charge piping out to the front of the car due
to the large rad and A/C condenser. It was definitely a learning experience
for me as I underestimated the amount of time needed to fabricate all of
the components. Thus, I have split the episode into two parts. In part 1 of
the installation, I fabricate a throttle inlet adapter to fit the FD
throttle body, position and mount the Intercooler, build charge piping, weld
on a BOV flange and IAT bung, fabricate an aluminium water tank with
inlet/outlet/fill bungs and mount the heat front heat exchanger.
13B Rotary Engine Disassembly With Lynnette And Aaron
What happens when you run a 500HP bridgeported 13B at 16 PSI at the top of
4th gear with a suspected intermittent secondary fuel injector? You end up
driving home on half an engine and feeling very Sad Panda indeed. With no
compression on the rear rotor of the first rotary I've ever blown, there
was nothing to do but pull apart the engine and asses the damage. Not
wanting to miss an opportunity to get her hands dirty, my dear friend
Lynnette joined in on the fun and helped pull apart the damaged block. I
stole her rotary virginity and she'll never be the same again.
Part 39: Front Suspension & Rack and Pinion Conversion, Part 1 - My 76 Mazda RX-5 Cosmo Restoration
I know it's been a while and since the front suspension work is still
ongoing, I've decided to split it up into two episodes. So for part 39 of
my '76 Mazda Cosmo restoration, I begin the work of updating the front
suspension and converting the car from recirculating ball steering to rack
and pinion. While my original goal was to mount the entire FC RX-7 front
subframe, it became obvious very early that was not feasible. Instead I
began combining parts of the RX-7 suspension with the Cosmo suspension to
create a unique solution. Once the basics were laid out, conversion to rack
and pinion steering began utilizing a NA Miata steering rack. And then I
hit a silly, obvious snag...
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.
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! :)

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.
REPITO: NO REBUILD, el motor no funcionará puesto que no tiene juntas de
estanqueidad, es un video de propósito meramente instructivo.
