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.
Hemi Buildup on a '55 Chevy Bel Air! - Roadkill Ep. 29
In Episode 8 of Roadkill we introduced you to the greatest engine swap
project ever—a Hemi into a 1955 Chevy Bel Air. Nearly two years later, we
finally get Mike Finnegan's Mopar-powered Tri-Five on the road, but not
without a few problems along the way. Blown head gaskets, frayed wires, and
severe sleep-deprivation are all overcome as Finnegan, Freiburger, and
friends push to get this polarizing project car running again in time for
an epic road trip.
The BlaspHEMI '55 Chevy rides on a Jim Meyer Racing Gasser tube chassis
with Viking coilover dampers and Firestone Cheater slicks out back. Up
front the car has a tubular straight axle, parallel leaf springs and tires
small enough to fit on a VW Bug. The rear axle is a John's Industries
9-inch with 5.43:1 gears. The Hemi began life as a 528ci Mopar crate
engine, which Finnegan rebuilt with a 0.030-inch overbore, ported aluminum
heads, and a Comp Cams solid roller cam. The mill is topped off with a
Hilborn stack injection system with EFI controlled by a FAST EFI ECU. An
Aeromotive Stealth fuel tank and pump provides the fuel while MSD provides
the spark. The engine is backed by a Tremec Magnum six-speed manual gearbox
with an American Powertrain installation kit and a twin-disc clutch. The
car was wired with a Speedwires kit and the guys built their own fenderwell
headers using parts from Hedman.
To save weight, the original steel front clip was swapped out for a
lightweight fiberglass tilt front end from Unlimited Products and the
windows were replaced with lexan parts from ProGlass. The rollcage is a
10-point arrangement built from chrome-moly steel and TIG welded to the
floor and frame. To save a ton of time, High Tech Auto Wraps covered the
car in flat black vinyl instead of paint while the last of the parts were
installed onto the car.
Roadkill appears every fourth Friday on the Motor Trend channel.
