This1967 Porsche 911S coupe was purchased by the seller out of San Francisco, California in 1979 and has been modified with numerous performance upgrades, a bare metal repaint, and new interior. Thetwin-plug 2.25L flat-six was built by Ed Mayo and features Venolia pistons, a knife-edged crank, modified Weber 40 IDS carburetors, and more as detailed below. In addition, extensive work was performed on the body, suspension, and interior as detailed below. The car was recently serviced in preparation for sale and is being sold with a set of megaphone exhaust stingers with silencing internals, an OEM air cleaner, records and documentation of the build, a Porsche Kardex, and a clean California title in the seller's name.
When the exteriorwas stripped down to bare metal it was discovered that the right-side body panels had been previously replaced with parts from a 1968 car. The chassis was then carefully checked for square and twist on two occasions finding no issues. The only corrosion present was located in the lower two corners of the rear window, so OEM corners were TIG welded in place. All of the factory undercoating was scraped off by hand, and the bare metal tub was sprayed with a commercial quality, zinc-rich primer followed with semi-gloss black. The exterior was refinished using acrylic urethane over epoxy primer in yellow, and painted orange stripes and decals have recently been added.
The front lid is a lightweight, Balsa-reinforced fiberglass piece, and the rear lid and bumper are lightweight fiberglass with local reinforcements to minimize stress cracking. The side and rear windows are Lexan polycarbonate. All chrome was refreshed during the refurbishment process, including the bezels for the Bosch H1 headlights, quarter window hinges, latches, and door handles.
The front suspension has been upgraded with an H&H 19mm sway bar with slider arms, adjustable drop links incorporating spherical ball joints, 20mm front torsion bars, custom Delrin bushings for the A-arms, Koni adjustable shocks. The stock 1967 S struts were re-machined to provide 17mm raised spindle height. The rear system includes anH&H 19mm sway bar with spherical ball joints, 25mm torsion bars, custom Delrin bushings for the spring plates, modified banana arms with spherical ball joints at the inner pivots, and single-adjustable Koni shocks which were rebuilt and re-valved for 50/50 damping performance.
The 15″ Fuchs alloys were refinished by Harvey Weidman and measure 6″ in width up front and 7″ in the rear. Spacers are used along with longer wheel studs to maximize track both front and rear. Subtle flaring of the rear wheel arches allows clearance for the 225/50 rear tires, while 205/50 tires are fitted up front.The Hankook Ventus R-S2 and are said to have approximately 90% tread left.
The interior has been modified with Recaro sport seats and afiberglass dash panel that eliminates the speaker cutout. Custom seat belts were created using parachute hardware stitched by a parachute harness fabricator. Additional touches include Perlon carpeting, a black headliner, and 1968 model aluminum window frames that have been de-anodized and polished to look like their OEM chrome plated equivalents. The rear seats have been replaced with vinyl-covered aluminum panels.
A Momo Prototipo steering wheel features a spoke-mounted horn button and was installed in 1979. The odometer currently shows 98,075 miles, which are deemed correct for the chassis. The factory 901/02 5-speed manual gearbox is equipped with a lightened flywheel and aluminum pressure plate. The first gear synchros are said to be tired but are in serviceable condition, and the gearbox reportedly does not grind when shifted with care. All fuel, brake, and oil lines are secured using cushioned loop clamps and the lines themselves are stainless steel over-braid lines from Earl's Plumbing.
Under the rear decklid, a 2.25L short-stroke (66mm) flat-six was built and blueprinted by Ed Mayo from late 1994 to July 1995. Inspiration for the build came from the original engine size of the 1970 911ST, which was 2.25 liters and used 46mm Webers. This engine is constructed using a sand-cast, aluminum case from a 1968 911L. Build details include a shuffle-pinned case, S cams, 85mm Venolia pistons, Total Seal rings, 2.2L connecting rods, 46mm and 40mm valves, 37mm intake ports, 36mm exhaust ports, a knife-edged, 911S counter-weightedcrankshaft, boat-tailed webs, a 911SC oil pump, Bosch twin-plug distributor, and more. The compression ratio as constructed is 10.1:1.
Performance Oriented modified the Weber 40 IDS carburetors to have 43mm bores and 35mm main venturis with float bowl baffle plates, 906 style tall auxiliary venturis, and remote float bowl venting. Tall intake manifolds are by PMO, and the included OEM air cleaner has been modified to be short enough in height to install and clear the rear lid. The exhaust has been upgraded with 1.5″ Jerry Woods headers and a 911R-style twin-pipe muffler. A set of stinger megaphones is also included with the sale, and both systems have perforated inner cores to limitnoise.
The engine pulls smoothly through the power band without flat spots and starts routinely within one full revolution of the engine during cranking. Output is estimated at 210 hp and 155 lb-ft of torque with a 7,500 rpm redline. The car has been recently serviced in preparation for sale with work included torqueing the heads and rocker shafts, setting the valves, and adjusting the Webers. The CV boots were replaced, and the suspension was re-aligned and corner balanced. Recent compression and leak down test results have been provided and are as follows:
Stopping power is provided by aluminum S calipers with 48mm pistons and S discs up front, L-type calipers and 911SC discs in the rear, and dual Girling master cylinders with an adjustable balance feature. A 20-quart aluminum oil tank was custom fabricated to fit with the spare tire in the front trunk, and additional cooling of the engine oil is provided by an aluminum cooler with stone shield protection mounted ahead of the right front wheel.
A Porsche Kardex confirms the chassis number. I performed most of the previously mentioned work himself apart from the engine build, though records for the Ed Mayo build, re-valving of the Koni shocks, original suspension alignment, and wiring diagrams are included. The following items also come with the car:
