Thanks Mark.

It was a very memorable trip...purely automotive fun with a little bit of work thrown in.

Lots of memorable moments....here's a few snap shots.

A quick visit to say hi to Hori-san (Workshop Manager)...

An early morning stroll to Mazda's R&D Centre (Yokohama)

Checking out Vintage Yoshino's latest stock and restorations (Yokohama).

Nissan Global Headquarters (Yokohama)

2013 Tokyo Motorshow

One of the highlights was an impromptu road trip (in Hayato's RX-8 Taxi) up into the mountains of Okayama to finally meet the former President of the Cosmo Sport Owners Club of Japan, Matsuda-san. Hayato is a young Mazda engineer who like me has an undying passion for the rotary engine.

This is his L10B Cosmo Sport.

He and his wife also took us out to dinner at his favourite Chinese restaurant.

As you do when you're in Hiroshima (well it's what I do

)...

One of the men who I owe my life's passion to.

A bit of inspiration for my build...

A quick run down to Kokura to inspect Automotive Plus' new storage facility.

Not a bad view from the facility...

Also dropped into....

Back to Hiroshima...

The breakfast of champions (Okonomiyaki)...

Up to Nagoya...

An unexpected visit to USS Tokyo auction house. The biggest in Japan - 10,000 cars auction in one day....mind you it's only once a week there though.

Some Euro-trash! :shock:

A little Mazda shrine I found at a Super-Autobacs in Ueda (Nagoya)

Of course the one and only Mt Fuji! :mrgreen:

The good news is that there has been some excellent progress on the NC in the last few weeks. An update isn't too far away.

Cheers,
Danny

Engine build time!!! :twisted:

In mid-November all the engine components returned from having their various modifications done (such as machining and balancing).

The inlet and exhaust ports in the rotor housings had their final machining and hand finishing completed. Man these are huge!!!

To improve heat transfer in the "hot" area (between the spark plugs and the exhaust port) of the rotor housings, a series of grooves were machined in the water galleries to increase coolant to alloy surface area. This has been long used by Racing Beat in the US to minimise localised dimensional change of the rotor housing in the "hot" area.

...as mentioned earlier, to minimise this risk even further, post radiator coolant will be delivered at the two additional ports machined adjacent to each of the spark plug holes.

The rotors have all been lightened, side clearanced and balanced to 10,000rpm.

....but there is one last job that has to be done before the engine can be assembled.

Cheers,
Danny

Write the japan trip off as a tax deduction? Open Automotive Plus up to the general public so you get interrupted? Speak to the environmental department for a permit to allow little birdies to be sucked in through the throttle bodies?

is that an f40 GTE?

THX
for the pics and posts, can't believe the NSX and F40 on the hoists.
Can't wait to hear the 20b up and running. The was a cosmo in NZ a few years back, which I saw run down the 1/4 mile, mad sound.

There been two cars that I wish I had never sold, one was a mint 1965 XP, the other was my S1 Rx7 with a BP 13b. Still nothing beats the sound of a rotor I.M.O.

Love the build!

You'll have to wait and see!

BTW It's not that exciting. :lol:

I can't comment on the GTE bit James...but it definitely was an F40! :shock:

Thanks toppertee. Me too...its finally getter closer to becoming a reality. Yes the 20B has a sound all of its own. :twisted:

It's an automobile museum owned by Toyota, not a museum full of Toyota's.

So the last thing to do before being able to finally assemble the engine was to block off the all the side inlet ports that are no longer required.

The perfect material for the task is Devcon Plastic Steel Putty. At around $130 for 500g it's not cheap, especially when I need to fill six rather large inlet ports! :shock:

So here's the process.....combine the two components.

Stir away until it is properly mixed together.

Then start filling the ports as quickly as possible before it hardens up!

Then repeat five more times.... :mrgreen:

And done!

Cheers,
Danny
