The body color is Millennium Jade

Based on the 230 Cedric two-door hardtop, this model has a cooler, more American styling than the 330 Cedric that followed.

The theme in building the car was that it should be easy to drive in town and enjoy driving without stress, without thinking about competing. As it is an old car, it has been restored and given what is commonly known as fine-tuning.

As for the specifications that are of interest, the finish is so superb that you wouldn’t notice it if you weren’t told, but the front and rear wings are wide wings with the original lines. The front and rear fenders have been fitted with wide fenders while maintaining the original lines. As expected of a company that specializes in bodywork, the precision of the fitting is superb. The bonnet and boot have also been painted, so it’s hard to tell at first glance, but they’re made from carbon fiber. The exterior color is also a specialty of the Yokomaku representative and is Millennium Jade from the R35 GT-R T-Spec.

“The subdued color suits the old car well, doesn’t it?”

He told us.

It sounds like a musical instrument

As for the engine, which is their specialty, it is a fully tuned L28 modified 3.2L, but instead of the old-fashioned peaky specification, it is an injection carburetor specification for comfortable street driving and is managed using a Link CPU.

The engine itself is fitted with 89mm prototype pistons, connecting rods, and a crankshaft made by OS Giken, a 46.5mm intake, and 38.5mm exhaust with a high cam with wide overlap, big valves, reinforced valve springs, and titanium retainers. Combination. The head cover is based on a JMC with a VeilSide Yokomaku SPL process. A JMC head cover and custom-made tappet cover are fitted to it.

The key point of this L-type engine is that the intake manifold is made a little longer, but more importantly, the amount of effort put into the exhaust manifold was extraordinary. The theory is to stick to equal lengths in the normal way of making them, but the VeilSide Yokomaku representative was conscious of the echoing sound of the tacho leg in terms of making a good sound.

It was also produced with a focus on the fact that by matching the frequency of the sound one cylinder at a time, it would sound like a musical instrument. The aim was spot on, and the exhaust sound is said to be the most pleasant sound possible. The 6-1 rows in the assembly are also unique to the VeilSide tuning, as the internal structure is spiral-shaped, which speeds up the flow and allows the exhaust to exit smoothly. He explained that this was a technique used in the drag era to improve efficiency and this time it was applied to the part that produces a good sound.

He does all the research and even carries out the actual work

There is not enough space in this article to list all of the things that Representative Yokomaku is passionate about the 230 Cedric that he has lovingly built. As well as tuning, the restoration work alone is also done with a focus on new parts, collecting what can be bought, and if something is not available, selecting only the best from reproductions. He even researches every single bolt and carries out the actual work himself, which is impressive.

The representative of Yokomaku concluded with this story.

“We don’t want to compromise. When we do something, we think it through to the last detail and work to get to the point where there is nothing more we can do. I haven’t done a lot of restoration work so far, but I don’t think the type of person like me should get involved in this field, because there’s no end to it. Because there’s no end to it.”

But even so, the 230 Cedric built by Legend Tuner Yokomaku was even better than we had imagined.
