What its like owning a 3 Rotor 20B RX-7
I have one of the most amazing custom RX-7s in the world. I want to share
my experience of owning and driving such a unique car.
I explain where the engine came from, why its so special, and what it does
to a Mazda RX-7
50psi boost 1200+hp Nissan RB30 - Ethanol E98
Nissan RB30 SOHC 3L engine built and tuned by JPC making over 1200hp on
Ethanol fuel. The engine still retains a factory block and crank.
Improvements come from a custom JPC turbocharger, manifolding, roller rockers and cam
gear. Fuel is fed via ID2000cc injectors and an Autronic computer system.
This engine has previously run 8.79 at 160.25mph (with less power) in a
full weight (3250lb) Holden VL commodore through stock suspension,
Powerglide transmission, 9in rear end and 28x9in slicks.

20B RX-7 vs GTR R35 - First run in RX-7
Drag race between brothers gets intense as Rob and Kevin duke it out on the
Rob recent purchased a 20b RX-7 and has never driven it on the strip. Will
he beat the 504 HP 2010 GTR?

The World's Fastest Lotus? - /TUNED
Frank Profera has spent six years making his Lotus go faster, stop shorter, and corner harder.
Though it only has to move around 2,150 lbs, Frank's Lotus makes 680 wheel
horsepower with a
twin-charged 1.8L engine; giving it a better power-to-weight ratio than
Mario Andretti's Formula One Lotus. It's an ongoing project that may never
be finished, because of Frank's never-ending obsession with speed. We had
to take it for a ride.

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.
26 PSI RX-7 GT35R Single Turbo
Ever wonder what happens if you hit fuel cut at 26 PSI on a turbo RX-7? Watch me do it on accident while
For those wondering, I had the ECU set to 20 PSI expectation and wastegate
to 26 PSI. ECU will go 3.5 PSI over its limits before it cuts the fuel.
Small logical error can make a huge difference.
I got lucky. I attribute a large part of that to the pre turbo water injection keeping my knock low and
combustion temps low while tuning.
