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.
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.

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 ].
