Sole remaining toyota 200GT? There were three in SA as of about 8 years ago, and one at a recent car meet (two months ago).

If my memory serves me correctly, I believe they also made a twin cam crossflow head for the L series 4 cylinder engines. Both are long since out of production and virtually impossible to find as well as the ancillary bits and pieces that go along with them.

Yes - that was a conversion for the L18 and was called the "MA-II":

As a Twin Cam enthusiast I am aware of a Dastun rallied in Australia in championships called a 710 coupe like a 240B but with twin cam engine and cr 5 speed. They were around the traps here in the late 70's and pretty competitive.

As the owner of the sole remaining 2000GT in Australia I was happy to trounce these guys in events and often got trounced.

When it comes to twin cam technology Toyota and Yamaha had the edge.

There were a bewildering number of special high-performance twin-cam heads made by Nissan in the Seventies and early Eighties for their four-cylinder engines. Plenty of these were never sold outside Japan, but we did get a sniff of them when Nissan used some of them in their rally cars, and on their occasional forays with Works circuit racers in countries outside Japan.

I'd agree about Yamaha up to a point, but don't forget about Honda, Isuzu and Mitsubishi - who were all messing about with twin-cams in the mid-to-late Sixties. However, Prince and Nissan had the upper hand over all of them in Japanese domestic racing - at least until the turbo years.

A friend of mine has an interesting Works race engine in his workshop at the moment. Its based on the L18 block, and I snapped it parked up next to his rubbish pile!:

If any one is interested in the 4 cyl Nissan twin cams of old, then this is a good page to have a look at.
