General Information

This 1967 911 Coupe, VIN 306607, has been built to be highly versatile. 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 were made. It has been built as a kind of stealth high performance SWB 911 without modifications of the original tub. It has five configurations depnding on components used:

1. Street
2. Track
3. Autocross
4. Rally
5. Hill Climb
   

   Performance Modifications include:

   • Engine
     Using the original aluminum case (a bit heavier but much stronger than magnesium), the engine has been modified as follows:
     • Rebuilt to single plug 2.7 liter specs by John Bunin of Werkstatt in Vista, California. Machine work was done by Competition Engineering.
     • New RS 2.7 pistons and cylinders
     • Two 2.7 engines were purchased to find a perfect crank and rods.
     • 930 cams
     • 40mm PMO carburetors with 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 Porsche oil lines
     • Monty (Australian built) stainless steel Monte muffler, Dansk stainless sport muffler and custom minimum baffle straight-through muffler
     The engine has dyno'ed at 220+ horsepower and 0-60 is under six seconds.

   • Transmission
     There are two transmissions:
     • Original 901 which has been modified to a 4-speed with short gears for hill climbing.
     • 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
     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
     • Carrera 3.2 calibers in the rear with Zimmerman vented rotors using the great adapter kit made by Michael Moran of the Early 911S Registry.
     • Koni shocks
     • Elephant Racing polybronze bearings
     • Hollow torsion bars

     The car was aligned & corner-balanced.

     It also has had significant (bolt-on) other 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 Seats, used for sports applications
       • NOS leather Sport Seats from a '73 911S, used for street

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

     • Two sets of seat belts:
       • Schroth 5-point harnesses for sports applications
       • Retractable 3-point belts for street

     • 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 fog lights (NOS grilles and lights)

     • Two sets of wheels & 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, and 22mm spacers are installed in the rear, but no flares have been installed.
       • For sports purposes, a set of 7" wheels are mounted front and rear, with Yoko AO32R 225/50's front and rear.
     

     Other Work

     At one time I had given some serious thought to taking this further along the 911R inspired Sports Purposes Rallye car process. But I decided against it, given that the original tub is in such great condition - no significant rust, no collision damage/repair and perfect gaps. I really hate to "molest" these great cars and all of the modifications (except the engine rebuild) are bolt-on, bolt-off and the car delivers high performance in a low-key, original look.

     
     

     Planned Uses

     As mentioned, this is a purpose built car that has five possible configurations: street, track, autocross, rally and hill-climb. 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 are being implemented.

     Configurations

     Street - Street use configuration includes:

     • Original hood with hood-mounted Cibies
       
     • Through-the-grille fog lights
       
     • 7x15 911R wheels with Yokohama AVS ES100 225/50 street tires in the rear and 6x15 deep sixes with 205/55's in the front
       
     • Stainless sport muffler
       
     • 3-point retractable seat belts
       
     • 5-speed short gear 901 transmission
       
     • Sport Seats

     Track - Track configuration includes:

     • The original hood with Cibies is replaced by a second hood with no lights.
       
     • Heavily modified sport muffler (read unrestricted) with dual outlets
       
     • 7x15 Fuchs with Yokohama AO32R 225/50 semi-racing tires front & rear
       
     • 5-point harness

     Interior Set Up For Track

     Autocross, rally and hill-climb configurations are similar with some changes.

     Summary

     Despite this cars performance modifications, it remains SWB 911 a few nuts & blots away from its original configuration. It still has all of its original engine, original transmission, original panels and original color. And because of its performance modifications, it's a great car for a number of uses: simply driving in a spirited manner on the back roads of Central Oregon or a variety of sports purposes. Out of 30 Porsches I have owned this is my favorite one.
