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.
SCREAMING 20B rotary engine dyno ~ JPC
Centreline Suspension's 20B PP rotary engine from their Mazda RX-7 Sports
Sedan circuit racer on the Dyno at JPC.
Rotofry 13B Turbo Hilux runs 13.6@103mph.
This is my 13B turbo powered Hilux which
only makes 276hp ATW. In this video I run a 13.62 @ 103mph on street
slicks. Currently I'm having trouble shifting my S4 manual from 1st to 2nd
due to a bend sellector fork so thus the long delay between gears. I also
want to point out that the staging lady took forever to let me stage
becuase there was a problem with the starting beams.
323 Turbo rotary @ powercruise 2010
Cruising with Andrew in my 500hp 323. Boost was reduced to 17psi, but was still a
handfull. 2nd, 3rd & 4th gear bursts .210kph only about 1/2 way down the
straight (track speed limits prevented full speed all the way). Great fun.
This is a full street legal car. Taken by nokia 6610 phone.
