OS GIKEN famous TC-16 MA2 engine, Bluebird H510

The L-series Nissan engine made it's first appereance in 1967. It was widely used in racing due to it's so called 'bullet proof' bottom end. The main limitation was the head design, tuners began to search for ways to improve the performance.

In 1973 a Japanese engineer named Osamu Okazaki designed a whole new cilinderhead for the L-series engine. The design used 4 valves per cilinder and a narrow included valveangle of 20 degrees. Combined with racing cams, racing pistons and DCOE Webers the 1888 cc engine outputed 232p PS and 203 Nm of torque.

The actual design was build via wooden negatives which were made of cherry wood. The particular head 'TC-16 MA2' had a limited production and is still sought after by fans and lovers.

One of the chief engineers at OS Giken joined the company in 1994 and learned allot about their twin cam head designes. He also noticed that they still had the parts in the warehouse. He asked permission for building one more racing engine.

The movie shows the start up of this particular engine. It is still used for racing. They later shifted the rev limit from 9000 to 10500 rpm. Torque was still high at this large velocity's.

OS GIKEN is known for their sequential gearboxes, Limited slip differentials and clutches. A lot of people don't know but they had a big influence in racing history

@swimmerB0B I think they were looking for RPM with the 1600, and to meet racing class specs maybe they had to keep the OG block? And what makes the PHH so superior? I just have never seen them in use, and the DCOE's are at least still being built.

@swimmerB0B Wow... That thing sounds so so cool.

Anyway, my reasoning for the L16 was probably because the engine class for the race they wanted to enter was under 2 liters.

Thing sounds sweet, wow.

From what I known Japan didn't get theL20 engine, only the smaller version, even their bluebird SSS model used a l18

[swimmerB0B]

I don't think a Japanese engineer would devise/use Weber carbs.... why pass up the superior Solex PHH carburetors?? also, why would they choose to put that head on an L16/18 instead of the L20B, which is a vastly stronger bottom end? it doesn't add up when you consider all the brains and money coming together here...
