The Porsche 911 Type 993, produced from 1993 to 1998, holds a singular place in the 911 lineage as the final generation to use an air-cooled flat-six. Rauh-Welt Begriff, the Japanese workshop founded by Akira Nakai in Chiba, has made that platform the foundation for some of the most recognisable wide-body road cars in contemporary car culture. This 1:18 scale model from GT Spirit places the 'Son Goku' build — one of Nakai's named one-off creations — into the display cabinet with fidelity to its defining purple livery and exaggerated bodywork.
The Last Air-Cooled 911
The 993-generation 911, built between 1993 and 1998, closed the chapter on Porsche's unbroken run of air-cooled rear-engined sports cars. Its 3.6-litre flat-six, cooled by air rather than water, defines an engineering philosophy that Porsche engineers had refined across three decades. The compact standard body dimensions make the wide-body transformation executed by RWB all the more dramatic. To Porsche collectors, the 993 represents a fixed point: the last of a lineage that began with the original 901.
Rauh-Welt Begriff and the Identity of 'Son Goku'
Akira Nakai, known universally as Nakai-san, applies each wide-body conversion by hand, cutting and bonding overfenders directly onto the Porsche body. Every car leaves his Chiba workshop with a unique name. 'Son Goku' takes its name from Son Goku, the central character of the Dragon Ball Z manga and anime series, and carries a deep purple livery that makes the reference explicit. These are fully road-registered, street-driven vehicles — not race cars — and each build is an unrepeatable object. No two RWB cars share the same specification.
GT Spirit's 1:18 Scale Model in Resin
GT Spirit produces this 1:18 scale model in resin, consistent with their standard approach across the entire 1:18 range. Resin casting allows GT Spirit to reproduce complex surface geometry — the wide overfenders, the low ride height, the layered aero additions that define the RWB aesthetic — with precision that diecast tooling rarely achieves for heavily modified bodies. The model has no opening parts; surface and paint accuracy are where the detail resides. The purple livery, central to the Son Goku identity, is rendered in full across the bodywork.
In the Display Cabinet
The RWB Son Goku sits naturally alongside other GT Spirit wide-body Porsche 911 builds in 1:18, and pairs equally well with 993-generation Carrera or GT2 models that represent the standard production car this build began as. The purple colouring and anime cultural reference give it a visual anchor point distinct from more conventionally liveried 911s. Collectors who track Nakai-san's named builds — Stella, Pandora One, Rotana — will find Son Goku a coherent addition. The resin construction makes handling minimal; a glass cabinet is the appropriate home.
