How to build a Rotary Bridge Port engine
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 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.

This is my 13BPP FC3S. back in 2003. I was Dynoing the car and brake in the
engine at same time cause car was not street legal, so cant brake in the
engine on street. plus in my opion the Dyno brake in just much easier
and save a lot of time

20B PP Mazda RX8 great sound!
Panspeed Racing of Japan easily had the loudest car at World Time Attack
Challenge with Naoki Hattori behind the wheel. The naturally aspirated 20B
peripheral ported rotary powered yet subtle looking Mazda RX8 was competing
in the Pro Class and ran a best time of 1:35.57 for the event.
