1986 911 3.6 Conversion

Mark performed the conversion on this G Body 911 ten years ago. The buyer held on tightly but Mark was able to get it returned to the roost for some fun along with his 'magic touch' that increases the value every time he touches it!

1986 911 3.6 Conversion

This stellar G-Body in Grand Prix White over a black interior is one special hot rod. Mark originally got this Carrera in 2010 and he modified it with a RUF-style front valence, front-mounted oil cooler, Kinesis Supercup wheels, stiffer torsion bars, a Brembo big brake kit, sport bucket seats, a limited-slip differential, and a custom-built 3.6L engine sourced from a 964 Carrera. It also came factory optioned with Sport Shock Absorbers, a short shift lever, and a rear spoiler. Producing nearly 300 HP while weighing under 2,500 lbs, this 8.3 lb/pony 1986 Carrera is now offered for sale out of California with approximately 20k miles driven on the rebuilt motor.

And the best part is that this conversion has been approved by the California Air Resource Board (CARB) as compliant and has the sticker in the engine bay. Passes smog with flying colors!

This Carrera sports its original color of Grand Prix White along with an upgraded RUF-style front valence and factory rear spoiler. Some paint chips are noted on the front fascia and the hood is said to have been previously refinished for cosmetic purposes. The seller adds that the finish shows to be all original apart from the hood, paint meter readings are provided in the gallery along with a clean CARFAX report.  The three-piece Speedline-style 17” Kinesis Supercup wheels measure 8” wide in front, 9.5” wide in the rear, and come dressed in Dunlop Direzza ZIII tires dated from 2020/2021.


Inside, you will find a black interior with upgraded BF Torno Rally bucket seats mounted on adjustable sliders.  The rear seatbacks have been removed along with the radio, and a Sparco three-spoke steering wheel has been installed in addition to a set of drilled Rennline pedals.  The car was factory equipped with a shortened shift lever as well as a sunroof, cruise control, power windows, and air conditioning. Some wear is present on the carpeting and all instrumentation is fully functional.


The original engine was swapped in favor of a larger 3.6L flat-six sourced from a Porsche 964 in 2010.  The top-end was rebuilt, the rod bearings were replaced, the heads were ported to 993 specifications, and the cylinders were honed before new bronze valve guides were installed along with 993 SuperSport cams, 993 head studs, new Goetze piston rings, and a custom straight-through exhaust system.  The engine was fully resealed, and the swap was carried out with proper California legal documentation.  A dyno-tested output of 298 HP is sent to the rear wheels through a 5-speed 915 manual gearbox and limited-slip differential which were both rebuilt by G Box of Colorado within the last 5k miles.  An additional oil cooler was mounted behind the front valence, a Brembo big brake was installed along with a 930 Turbo master cylinder, and the torsion bars were upgraded to 23mm and 30mm diameter.  The results from a recent leak-down test are available for reference  along with a dyno sheet from JBA Performance Center. The original catalytic converter is will accompany the sale.
