This 2014 Porsche Cayman shows under 10k miles and is a highly modified example that was reportedly ordered new from Brumos Porsche by the seller’s brother. Shortly after taking delivery, the car was sent to BGB Motorsports in Daytona Beach, Florida to have the 2.7L engine replaced with a 3.8L flat-six from a then new 991. Over $70k was reportedly spent on the modifications, which also included adding 991 6-piston caliper brakes, JRZ RS Pro coilovers, RSS Tarmac Series lower control arms and toe links, a Cargraphic exhaust, a Guard limited-slip differential, a Techart & Crawford GT rear wing, Sparco seats, and a 4-point rollbar. The car was brought to California after the original owner passed away, and it was then tuned by BBi Autosport in order to pass the state’s smog test. This 981 is equipped with a PDK and is now being offered by the seller on behalf of his brother’s estate with receipts from the modifications, the original purchase order, a Porsche CoA, clean Carfax, and a clean California title.

Exterior modifications include an ITC carbon fiber front splitter and a Techart & Crawford GT rear wing. One invoice notes that the front bumper was replaced with a Cayman S cover and lip, and a dent is present above one of the side vents as pictured in the gallery. 18″ Porsche wheels can be seen mounted on the car in most photos, though two other wheels sets are included as detailed below.

A set of JRZ RS Pro dampers using Eibach springs have been installed alongside RSS Tarmac Series monoball lower control arms and toe links, a 991 GT3 adjustable front swaybar, and MSI 70mm wheel studs. The brakes were upgraded to a set of 991 6-piston calipers and 340mm discs. Pagis Racing RS29 pads were used front and rear in addition to Castrol SRF brake fluid.

The seller’s brother was a Porsche instructor, and multiple photos of the car on track wearing a vinyl livery can be seen in the gallery. A set of 18″ Forgeline GA3R wheels with Yokohama slicks are included in the sale, as are a set of BBS wheels wearing Hankook slicks.

The modifications continue on the interior, where Sparco Pro-ADV seats were installed along with a set of OMP 6-point harnesses. A PCNA Red 4-point rollbar was also installed around the engine cover behind the driver and passenger.

An AiM Solo DL data acquisition unit and Smarty video overlay system are present. The Sport Design steering wheel was a factory option, and the odometer shows just 9,933 miles. The seller estimates that 80% of the miles were accumulated on track by his brother.

Power comes from a 991-model 3.8L flat-six that was purchased new at a cost of over $17k. The install was completed by BGB Motorsports and utilized upgraded mounts along with BMC high flow air filters and a Cargraphic exhaust. A PCNA center radiator was installed with the engine, and the left radiator was replaced a few months after the initial install. The engine is mated to the factory 7-speed PDK transmission and runs to a Guards limited-slip differential.

After the car was brought to California, the seller had a set of stock 2.7L exhaust manifolds installed in order to get the car to pass California emissions. It was tuned using a Cobb Accessport by BBi Autosport in Huntington Beach, and reportedly passed emissions successfully. Since then, the car has developed a fault code as pictured above. The seller states that the car remains fully operational, and the code is believed to have been caused by the smaller exhaust manifolds. The set of Cargraphic race manifolds that were initially used during the build are included in the sale.

Over $70k of receipts from the engine conversion and other modifications are detailed in the gallery.

A Porsche Certificate of Authenticity is included in the sale along with the original purchase order.

A Carfax has been provided by the seller showing no accidents or other issues. Two exhaust videos along with a track shakedown video can be seen below.
