Rotary 20B turbo RX7 - Dyno & track
Built as an all-round event's car, Charles' Mazda RX-7 has undergone
serious chassis and engine changes including a Promaz Automotive
bridge-port 20B rotary engine. Boost
comes from a Garrett turbocharger while
the engine runs on methanol fuel controlled by a MicroTech LT16 computer
and LTC dash logger. Backed by a Jerico 5-speed dogbox, the clutch was
suffering on the Dyno
as the Promaz team got the car ready for Performance Car Mania. [

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.

20B rotary RX-7 Spirit R: The Ultimate Street Mazda
Built by Promaz Automotive, we think it's hard to go past Steve's wicked
Series 8 FD RX-7 if rotaries are your game. Limited to around 1500 unit's,
the Spirit R was the last of the RX-7's and featured a lot of upgraded
factory parts as well as a low 1100kg weight.
Now powered by a lethal Promaz triple rotor 20B extend port rotary engine,
power is aided by a Garrett GT42R turbo
and MicroTech fuel system and transmitted through an Albins 5-speed gearbox
and KAAZ rear end [ http://www.promaz.com.au ].
20B ROTARY ACTION! 20B DATSUN 1200 & 20B MAZDA RX3 - TNT 28/12/2013
On the final Test and tune at Willowbank Raceway for the year, Brad Mcilroy
was out testing his Mazfix prepped 20b Datsun 1200 ute as well as Russ in
his 20B powered Mazda Rx3. The PRODAT was testing some changes in the rear
end, keeping the newly added 10.5 inch tyres as well as some changes to the
4 link, and after a few tweaks had the car complete a full pass of 7.95 @
165 mph with a small back off down the deep end, a little slower then what
the car has run but a little more stable down the track. The Mazda Rx3 had
some issues most of the night but managed to get it down the track for an 8
second pass, also off its best, but once sorted should be back down to
where it was running before.
