Rotary Motorsports (Ben Hunt) 20B 1200HP+ 20B RX7 using twin GT35R and 90% Methanol mix being free reved. My apologies for the whooshing sound but this car was just too loud for any phone camera to deal with, the car literally shakes your entire body every time it's reved up.
This thing is a machine, the explosion at the end almost blew me away as you can see by the movement of the camera, ran low 8's previously with single turbo.
GODZILLA GT-R Group A R32 Nissan Skyline GTR - Bathurst 1000 1992
GODZILLA. The 1992 Tooheys Bathurst 1000 Winner and 1992 Australian Touring
Car Championship Winner, The R32 Skyline GT-R.
The WINFIELD Number #1 GT-R piloted by Mark Skaife and Jim Richards was the
winner at Mount Panorama for a 2nd year in a row.
WINFIELD GT-R won the 1992 Australian Touring Car Championship.
Driver Championships were also won by Skaife 1st and Richards in 2nd,
Longhurst was 3rd with the BMW M3 Evolution in the final Drivers
Championship Standings in 1992.
Australian Motorsport was changed forever after this event and proceeded
with an amalgamation of today's V8 SUPERCARS. This also meant the removal
and abolishment of turbo charged engines
in the top tier of Australian Motorsport and only 2 car Manufacturers that
compete for the title.
In this video the car is the GIO Racing GT-R with Mark Gibbs driving on the
day along with Rohan Onslow, they finished 6th at Mount Panorama.
The eventual championship drivers were Mark Skaife and Jim Richards in the
For those wondering why The Chase or "Caltex Chase" is not in the video:
Channel 7 decided to edit out The Chase section.
In 1987 Mike Burgmann died after his VK Commodore SS Group A became
airborne at 260km/h along the second hump on Conrod Straight.
Bathurst hosted the WTCC in 1987 and the FIA regulations did not allow
international tracks to have a straight longer than 1.5 km in that class,
the second hump was removed and "The Chase" added.
In 1991 the Winfield GT-R (Skaife) reached 293km/h along Conrod Straight,
similar speeds to the V8 Supercars of today.
The 1992 Tooheys Bathurst 1000 was stopped due to torrential rain and
multiple crashes. The results were compiled using the 143rd completed lap,
18 laps short of full race distance.
The Fastest Lap of the race was -- #1 Mark Skaife -- 2:16.47
The top 10 final finishing positions for the 1992 Bathurst 1000 were as

Why I picked the GT35R for my RX-7 over the stock twin turb
I cover the basics of turbochargers in
simple terms to explain why I chose the GT35R over T04Z or T78 or T88 etc.
It's all about air flow. Sure there are technologies that make the turbo more efficient in more applications but
the turbo is most efficient in an area
known as the compressor map.
Exhaust back pressure plays a huge
part when dealing with quick spool small turbos.
Large turbos deal with spool up and lag
I chose the GT35r for near stock spool up with more efficient 400 hp

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.
