Miura SV

Converting a 1967 P400

Converting a 1967 Lamborghini Miura P400 to a Lamborghini Miura SV is not only a matter of changing the appearance of the Miura's aluminum body, but when done properly includes changes to the engine, the power train, the suspension and the interior. Many SV Conversions only address the appearance of the car and are lacking the most significant improvements ever made to the car.

The primary reasons for converting to the SV version are the enhancements gained in handling performance, engine reliability and driver safety. Incorporating all the improvements Lamborghini made to the Miura during the seven years the car could be special ordered is a major undertaking, requiring highly skilled professionals to do the SV Conversion properly and completely.

In it's Day the Lamborghini Miura was a Super Car in the making, constantly being improved, ending up setting the course for Lamborghini. A True Legendary Car. The Miura Car was created from an after-work project of Mid-Mounting a V12 Engine Transversely in a Chassis and evolved into one of the Most Desirable, Best Looking Cars ever Manufactured in the World. A True Collector's Car and a Sure Investment.

Miura SV Conversion

Rear Body Section
By Cass Nawrocki
Nawrocki Fabricating MN, USA

Almost the entire rear section of the Miura was fabricated to Factory Spec and is made of aluminum. The SV rear fenders are flared which then requires the inner rear fender covers be widened to lower overtop the larger rims and tires. About the only piece of the original rear section Cass was able to use was the trunk lid. Fabricated to accommodate the Updated SV Tail-Lights, rear Bumper and Grill.

The Body Front and Rear Sections are ALL Aluminum as Original. No fiberglass was used and No Plastic was used. To eliminate any potential chassis flexing when entering a corner at high speed, the lighter weight chassis is steel reinforced. The Handling Performance is Superb. The Latching Systems for both the Front and Rear Bonnets are updated to the Single Release Handle opening system. This allows both the front and rear sections to be released from inside the car and opened by one person. Both the Front and Rear Latching System Pivot Points are reinforced providing a smoother operation and an exact fitment.

The Miura P400 - Bob Wallace and Ferruccio Lamborghini

In contrast to his rival Enzo Ferrari, Ferruccio Lamborghini had decided early on that there would be no factory-supported racing of Lamborghinis, viewing motorsport as too expensive and too draining on company resources. This was unusual for the time, as many sports car manufacturers sought to demonstrate the speed, reliability, and technical superiority through motorsport participation. Enzo Ferrari in particular was known for considering his road car business merely a source of funding for his participation in motor racing. Ferruccio's policy led to tensions between him and his engineers, many of whom were racing enthusiasts; some had previously worked at Ferrari. When Dallara, Stanzani, and Wallace began dedicating their spare time to the development of the P400 prototype, they designed it to be a road car with racing potential, one that could win on the track and also be driven on the road by enthusiasts. When Ferruccio Lamborghini discovered the project, he allowed them to go ahead, seeing it as a potential marketing device for the company, while insisting that it would not be raced. The P400 went on to become the Miura. The closest the company came to building a true race car under Lamborghini's supervision were a few highly modified prototypes, including those built by factory test driver Bob Wallace, such as the Miura SV-based "Jota" and the Jarama S-based "Bob Wallace Special".

Lamborghini Miura JOTA

Recreated by
Piet Pulford, UK

Below is Piet Pulford's Recreation of the Lamborghini Miura JOTA he built for racing. After Lamborghini track tested the Miura JOTA, Ferruccio Lamborghini decided to sell the car to a racing enthusiast. The new Owner sent a driver to pick up the car from Lamborghini and en route back home the driver crashed the car. The Miura burnt to the ground, likely due to the fuel tanks being divided and located on each side of the car. The Miura was completely destroyed.

The Recreated Miura JOTA, pictured below, the entire engine and power train were built by Bob Wallace personally in Arizona, USA. The engine and power train are as close as possible to an exact replica of the original Jota engine and transmission Wallace built in the 70s. It took Piet Pulford, from England, UK, 15 years to build the Lamborghini Miura JOTA.
