Theon Design's 421HP Porsche 911 Restomod Starts at RM2.46M
What Is the Theon Design Porsche 911 Restomod?
Theon Design’s Porsche 911 restomod is a bespoke, 421-horsepower rebuild of the classic 964-generation 911, featuring a full carbon fibre body and modern luxuries. Developed in the UK, it starts at RM2.46 million and targets affluent Malaysian enthusiasts who want classic style with modern reliability. “Priced from RM2.46 million, the hand-built coupe is aimed at Malaysian collectors who seek vintage character without sacrificing daily usability or 421 hp output.”
Based in Oxfordshire, Theon Design disassembles original 911 (964) chassis down to the bare metal, then re-engineers them with state-of-the-art components. The full carbon fibre body sheds over 200 kg compared to the original steel shell, while the interior receives premium leather, modern air-conditioning, and programmable digital instrumentation. Each commission takes approximately 12 months and is fully customised to the owner’s taste. For Malaysian roads, the company offers right-hand drive conversion at no extra cost—an essential requirement for local registration.

“At RM2.46 million before taxes, the Theon Design 911 delivers supercar performance in a vintage body.”
Performance and Driving Experience
The 421 hp 4.0-litre flat-six engine propels the 1,100 kg restomod from 0–100 km/h in an estimated 3.5 seconds, delivering supercar acceleration with analogue throttle response. Top speed exceeds 280 km/h, while a track-tuned suspension provides both agility and compliance.
Theon’s in-house engineering team fits adaptive KW dampers and a bespoke stainless-steel exhaust. The six-speed manual offers short gearing for rapid pace, and the optional lift system helps clear Malaysian speed bumps. Despite the enormous performance, the car remains docile enough for leisurely drives along KL’s highway network. Modern climate control effortlessly copes with temperatures above 35°C, a crucial upgrade over the original 964’s feeble air-cooling.
“Perfected, not restored. We don’t simply refurbish old cars; we re-engineer them from the ground up to create the ultimate driving experience.”
“The 421 hp output, combined with the lightweight carbon body, makes this restomod as fast as a contemporary 911 GT3.”
Malaysian Pricing and Import Realities
Theon Design quotes a starting price of RM2.46 million, but after Malaysian import duties, excise and sales taxes, the on-the-road cost can escalate beyond RM4.5 million. This figure excludes annual road tax exceeding RM10,000 and high-value insurance premiums.
Malaysia imposes a tiered import duty structure: fully built-up luxury vehicles with engines above 3.0 litres can attract duties of 30% to 105%. Combined with 10% sales tax and excise, the tax burden may nearly double the factory price. Buyers must also budget for shipping, insurance, and customs brokerage. Registration requires Puspakom inspection and JPJ type approval, a process that can take 8–12 weeks. Engaging a specialist importer is highly recommended to navigate these steps and secure the mandatory right-hand drive conversion, which Theon performs without additional charge.
“The effective on-the-road price in Malaysia can surpass RM4.5 million, factoring in all duties and compliance costs.”
Who Should Consider This Car in Malaysia?
This restomod is built for wealthy Malaysian collectors who already have practical daily drivers and can store the vehicle in a secure, humidity-controlled garage. It is not designed for everyday commuting or heavy traffic, but excels on weekend drives and exclusive rallies.
The carbon fibre body is resistant to rust, an advantage in Malaysia’s humid climate, but the car’s stiff suspension and low ground clearance make it ill-suited for unsealed roads or frequent multi-storey car parks. Typical owners own properties in neighbourhoods such as Mont Kiara or Bangsar, where dedicated parking and covered storage are available. Annual running costs—road tax, comprehensive insurance, and specialised servicing—can easily top RM30,000, so financial readiness is essential. Ultimately, the Theon 911 restomod is a rolling piece of art for those who prioritise craftsmanship and exclusivity.
“This is a collector’s piece for weekend drives and concours events, not a daily Kuala Lumpur runabout.”
How It Compares: Restomods in Malaysia
Theon Design positions itself between the ultra-premium Singer (above RM6 million) and the track-focused Gunther Werks (around RM3.5 million). With its extensive use of carbon fibre and bespoke interior, the Theon offers a compelling value proposition at RM2.46 million.
Local Porsche restoration shops can build modified 911s for RM300,000 to RM1 million, but these seldom match Theon’s level of engineering or international cachet. Theon’s cars retain the classic 964 silhouette while delivering modern crashworthiness and reliability. For a Malaysian buyer, the higher initial outlay brings a manufacturer warranty, global parts support, and a vehicle that holds its value exceptionally well. In a market where Singer waitlists run years, Theon’s shorter build times (around 12 months) are another practical advantage.
“Theon Design occupies a sweet spot: carbon fibre luxury at half the price of a comparable Singer.”
Common Questions
Can the Theon Design Porsche 911 be legally registered for road use in Malaysia?
Yes, as long as it is built in right-hand drive (RHD) configuration, which Theon offers at no extra cost. The vehicle must pass Puspakom inspection and receive JPJ type approval. A specialist importer can assist with the required documentation and duties.
What is the estimated total cost of bringing the 421 hp restomod to Malaysia?
With the factory price at RM2.46 million, landed cost after duties, taxes, and shipping typically falls between RM4.5 million and RM5.0 million. Annual road tax for the 4.0-litre engine will be around RM10,800–12,000, plus insurance of RM20,000 or more.
Does the Theon Design 911 come with an automatic gearbox?
As of May 2025, the standard transmission is a 6-speed manual. While Theon has not officially confirmed an automatic option, its bespoke manufacturing process means a dual-clutch PDK conversion may be possible on request. Prospective buyers should contact the factory directly.
