This 2006 Porsche Cayman S was acquired by the seller two years ago and has since been fitted with a GM 6.2L LS3 V8 crate engine mated to a Porsche 986 6-speed manual transaxle and an OS Giken limited-slip differential. The car is finished in black over black leather, and additional modifications include a Kennedy Engineered clutch, flywheel, and adapter plates, custom built axles with 930 CV joints, a third radiator, electric power steering and water pump, 19″ Avant Garde wheels, and more. Now showing 89k miles, this LS3-powered Cayman is offered with build records, a clean Carfax report, and a clean Nevada title in the seller’s name.

The exterior is finished in black (741), and carbon fiber air intake scoops have been added to the exterior. No accidents or other damage are indicated on the Carfax report.

Factory alloys are replaced by black 19″ Avant Garde wheels that wear Michelin Pilot Sport 4S tires. The brakes utilize red-painted calipers and drilled/ventilated rotors all around.

Power-adjustable heated seats are trimmed in black leather, and branded floor mats cover the footwells. Equipment includes power mirrors, a CD stereo, and a three-spoke steering wheel.

The odometer shows just under 89k miles, approximately 3k of which were added during the seller’s ownership.

Power is provided by a 6.2L LS376/480 V8 crate engine, which is linked to the rear wheels via a 986 Boxster S-sourced 6-speed transaxle with an OS Giken limited-slip differential. The seller states the engine has approximately 1,500 miles on it, and oil changes were performed at 60 and 500 miles. Additional modifications include a Kennedy Engineered clutch, flywheel, and adapter plates, custom built axles with 930 CV joints, a third radiator, electric power steering and water pumps, Evans waterless coolant, and more. The seller states the LS3 ECU triggers a “higher than expected idle” code on occasion, and the Porsche ECU shows multiple faults as a result of the swap.

A stainless steel exhaust system with Flowmaster dBX mufflers are fitted, and additional underside photos are included in the gallery below.

The copy of a build sheet lists factory options and a $63,455 retail price.
