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.

Here you are a video about a modified Mazda MX-5 I saw during a drifting
event at a little racetrack here in Italy. The 1.8 litres DOHC engine has
been bored out to around 1.9 litres, new forged pistons has been added as
well as a Garrett GT2560R turbo. The car
should now be able to produce a power between 300 and 350 bhp.

Turbo MX-5 Traction Problems - ~350 WHP in a 2500 lb 2006 NC MX-5
People want to know what our car does 0-60; we'd like to know too!
Unfortunately with now approaching 350+ WHP we can't put the power down
fully until 4th gear, sometimes not even then. We will take donations for
10.5 slicks for those that REALLY must know!
Stock motor, raced and abused, over-revved, subjected to far too much
experimentation--still 210 compression across the board and doesn't burn a
drop of oil after 3 years. Spools the Garrett 2860RS to 5 psi by 2300, 10
psi by 2700, 13 psi final Boost.
Tested to 15 psi, put down 325 to the wheels a while back at a couple psi
less and with Boost leaks that are
now fixed. We will be heading to the Dyno in the next week or two to
get the new numbers.
Tires are Falken FK452's in a straight line friendly 225/50/16 profile. At
the 52 degrees Fahrenheit we're working with here the R-Comps don't do any
better without some serious preheating.
Of note this is setup with the Blow-Through 3" MAF setup. So far so good!
The throttle response is phenomenal, HP definitely up a few, and spool
dropped about 200 rpm.
