General Information

In March of 1968 Porsche published a bulletin entitled "Information Regarding Porsche Vehicles Used for Sports Purposes" that provided details, specifications and guidelines on building a car for competitive events such as rallying and circuit racing. This 1967 911 Coupe, VIN 306607, has been built following those specifications (with a few modern mechanical updates). The project started with a collision-free, and minimal rust California Black Plate car. Over 30 tubs were looked at before this one was chosen. A great deal of originality was maintained while many performance enhancements have been made with an emphasis on a recreation of a period correct rally car that would hav been built by a privateer.

306607 was featured in the December, 2008 issue of Excellence Magazine in a well researched, well written (and accurate) article by Peter Linsky.

Modifications include:

  • Rally Accessories

  • Engine


    Original Numbered Engine Case - The Rest Has Had Some Modifications!

    Using the original aluminum case (a bit heavier but much stronger than magnesium), the engine has been rebuilt to single plug 2.7 liter specs by John Bunin of Werkstatt in Vista, California. Machine work was done by Competition Engineering:

    • New 2.7RS Mahle pistons and cylinders
    • Two 2.7S engines were purchased to find a perfect crank and rods
    • 901 "Solex" cams
    • 2.7S heads
    • 2.7S valves
    • 2.7S oil system
    • 40mm PMO carburetors with 911R rain hats
    • Turbo valve covers
    • Billet aluminum pressure plate (EBS Stage 1) with 215mm clutch disc
    • Radiator style oil cooler, 12 quart dry sump system and polished Porsche oil lines
    • Mufflers: Monty (Australian built) stainless steel; Dansk stock; custom minimum baffle (straight-through)

    The engine has dyno'ed at 220+ horsepower and 0-60 is - quick (but more fun on twisties).


    Fabricated Oil Cooler Lines

  • Transmission
    There are two transmissions:
    • Original 901 4-speed.
    • 5-speed 901 with Porsche's traditional short gears: A-F-M-S-X. This transmission is used for street, track, autocross and rallies.

  • Suspension
    Modern suspension and brake upgrades, done by German Master Tech in Bend, Oregon include:

    Front:

    • hollow torsion bars
    • Weltmeister 19mm sway bars
    • Carrera 3.2 calibers with Zimmerman vented rotors. A-arms with Koni struts (with Koni inserts) and cross members from a '73 911S were installed in order to accommodate the larger calipers.
    • Elephant Racing polybronze bearings
    • Strut brace
    • Turbo tie-rod ends
    • Dual circuit master cylinder

    Rear:

    • Adjustable spring plates

    • Elephant Racing polybronze bearings
    • Hollow torsion bars

    The car was aligned & corner-balanced.

  • Additional Performance & Cosmetic Work:

    • There was slight rust in the floor behind the driver's seat and under the battery box, and the driver side of the floor-pan and the battery box were replaced to exact Porsche factory specs by Urs Gretener of Gretener Prototye Engineering/Corroserie Gretener. Gretener also installed the rollbar.

    • There was also slight rust in the seams where the front fenders mount to the tub (fortunately all on the fenders) and in the door bottoms. Repairs and a complete repaint in the original color of Bahama Yellow were done by AutoWerks of Bend, Oregon.

    • The interior, including carpets, dash, door panels and headliner was done by Autos International.

    • There are two sets of seats:
      • Replica Scheel R2's, made by Vintage Seat

      • NOS factory rally bucket driver's seat & passenger's lightweight sport seat (ca. 1967-1968)

    • Roll bar modifications, including head restraints, were done by German Master Tech in Bend, Oregon.

    • Four sets of seat belts:
      • Period Autoflug 4-point
      • Schroth 5-point harnesses for sports applications
      • Retractable 3-point belts for street
      • Aircraft style lap belts

    • Two hoods:
      • Original hood mounted with NOS Cibies for street & rally use
      • Second hood painted in original color with no lights used for track, autocross and hill-climbs

    • H-1 Headlights

    • Through-the-grille Bosch fog lights (NOS grilles)

    • Two Rear Bumper Configurations
      • Set of bumper guards with factory nudge bar mounted
      • Second set of stock bumper guards with no nudge bar

    • Two sets of wheels & three sets of tires:
      • For street use, NOS 911R 7x15's in the rear (with 22mm spacers) and deep six with hearts 6x15's in the front - the same combination that the Porsche factory used on the 911R. Yoko AVS 225/50's are mounted on the rear and 205/55's on the rear. The inside of the fenders have been slightly shaved to accommodate the larger size wheels and tires, but no flares have been installed.
      • For shows, a set of period Dunlops, 500M-15 in the front and 550M-15 in the rear mounted on the same wheels as the Yokos
      • For sports purposes, a set of 7" wheels are mounted front and rear, with Yoko AO32R 225/50's front and rear.

    Planned Uses

    As mentioned, this is a purpose built car that has three possible configurations: show, street and track. It's first track event was a Porsche DE day at Portland International Speedway where I drove it in Novice Class. Driven by an instructor in Expert Class it held it's own against Turbo's, GT3's and the like. It recently ran at Infineon (Sears Point), driven by Tim Morris my mechanic, and performed well. Jeff Gamroth of Rennsport in Portland made a few recommendations regarding performance, mainly wheel and tire size, that have been implemented.

    Summary

    My goal was to be respectful of the authenticity of this car during its build. Despite extensive performance modifications, it's still an authentic SWB 911 a few nuts & blots away from its original configuration. It still has its original engine case, original transmission, original panels and original color. It's performance modifications make it a great car for simply driving in a spirited manner on the back roads of Central Oregon -- or for a variety of sports purposes. Out of about 30 Porsches that I have owned this is my all-time favorite.
