Description
OFFERED WITHOUT RESERVE
First launched in 1982, the Porsche 944 followed in the footsteps of the 924 of 1976 and the 928 of 1977 in adopting a front-mounted, water-cooled engine and rear-mounted transaxle configuration which, at the time, was part of Porsche’s planned evolution away from the rear-engine layout of the 911. The new entry-level model took inspiration from the flared fenders of the 924 GTP LeMans prototype with its fresh hatchback design while retaining the familiar and excellent-handling chassis of the 924 underneath.
In naturally aspirated form, the 944 produced 150 horsepower from its all-new 2.5-liter overhead-camshaft four-cylinder, later jumping to 217 horsepower and 243 pound-feet of torque through the addition of a K-26 turbocharger in the 944 Turbo of 1986. The new turbocharged model silenced any remaining calls for more power and also introduced revised front-end bodywork, stiffer suspension components, updated brakes, and wider wheels and tires.
The consignor of this 1986 Porsche 944 has owned it since 1989 and is believed to be the second owner. A failing transaxle some years ago resulted in the installation of a Porsche 968 six-speed, and later a failing engine was followed by a custom 520 hp Chevy LS3 V8 transplant.

Ownership History
The accompanying CARFAX Vehicle History Report places this LS3-Powered 1986 Porsche 944 in Arizona. The current owner purchased the car in 1989 with approximately 40,000 miles on it. He believes he is the second owner and that the original owner was an employee at Scottsdale Porsche (where he said it was sold new). Some years ago, he was driving in Northern California, and the transaxle was giving him problems, so it took it to a Euro shop there who swapped in a rebuilt six-speed transaxle from a Porsche 968. Then some years later the original engine was going out, so he spent close to $50k having a high-performance Porsche shop in Las Vegas custom build and swap in a 520-hp LS3.
