Here's the included for sale ad from 1991.
"Scirocco Fact Sheet"
-For Sale-
The car is the 1976 Special Edition, of which some 20,000 were made, which VW used to introduce fuel injection. Special features included movable vent windows and rear washer/wiper. The car has been continuously refined and upgraded over the 15 years since - always with the intent of extracting more of what it could be without making it in any way radical.
Engine
The engine is from a 1984 GTI - the largest that fits the stock engine bay without modification.
Exhaust is a more efficient 4-into-2 stock 1979 manifold, feeding a Techtonics 2-into-1 collector, to a Rabbit Hutch exhaust which has been further modified for more power and less noise. It mimicks the stock European exhaust, gives significantly more power than stock and has a more pleasant sound, but is not noticeably louder.
Cam is the European GTI G-Grind. (A Schrick 272 and adjustable cam-timing wheel are also available.)
A larger throttle body also adds power; an Audi fuel regulator improves throttle response.
Oil was tested frequently for contaminants for several years, and changed at 2,500-mile intervals thereafter.
Transmission
Wider ratio than the close-ratio GTI box, it cruises much more easily. Ratios are fairly evenly spaced (unlike some which have four close ratios and a long fifth). The transmission was selected to idealize the car for "active" high speed touring. It has just been rebuilt )new bearings and synchros).
Suspension
Springs and bars from a stock GTI provided the best balance of the many improvements tried. Coils are cut slightly (professionally heated and retempered) to return the car to stock ride height. Shocks are Tokico Illumina 5-position adjustables; all 4 can be reset from above in about a minute. Wheels are original to maintain the stock look; the Continental CH-51s grip well, ride and wear decently, and give exceptionally good feel at the limit.
Two new studded snow tires, also on stock rims, are included. All of the original suspension parts are also available.
Brakes
A transplanted vented-disc GTI brake system included braided-steel reinforced brake lines which improve pedal feel. (Fluid has been changed every 2 years)
Lights
400 watts of high beams, fed by fused heavy wiring and the 90-amp alternator from an Audi 5000. No additional lights, in order to preserve the stock look.
Body
Stripped to bare metal, hand blocked and hand rubbed. To maintain the stock look, the original paint formulation was flown in from Germany.
The only alteration to stock is the front air dam (necessary to keep the car stable at the higher speeds its bigger engine provides), and an internally-adjustable left door mirror. The air dam is a stock VW part, but from a later year; the original chin spoilder is available.
The car recently got a new windshield to restore the original clarity. (After several years, fine sand chips were causing a bit of sparkle in bright sun.
Interior
Recaro-designed seats used by VW varied from year to year; these were, I think, the best of the series. Interior materials are the highest grade of Naugahyde (much better than stock), but as near the original color as possible. The stock "fake stitching" pattern was followed as closely as possible, but the new interior is all hand stitched.
Oil pressure and temperature gauges, and an outside air temperature readout, have been added. The speedometer has been calibrated to optimize accuracy between 60 and 90 mph.
Price
Best offer above $5,000, exclusive of sound system. (The car was appraised at $8,000, and has not changed significantly since). Must wait until a new car (ordered) has been delivered
