Porsche 928 Interior Restoration

Porsches may be pricey to own, but they’re certainly worth every penny. This 928 is an autobahn-ready grand tourer featuring some unique features not typically found in modern vehicles.

Restoring the Interior

As iconic Porsches go, the 928 is truly iconic. Although intended as a replacement for the 911, its purpose changed entirely when it became an elegant grand tourer with four seats and plenty of luggage capacity. Equipped with front-engined V8 power and Pirelli P7 tires for unparalleled roadholding capabilities compared to any large GT before it.

Its sleek lines and distinctive shark nose differentiated it from other Porsches at the time, making it the most modern-looking Porsche ever created. Additionally, its symmetrical doors, round headlamps and curved rear quarter windows gave it its own identity that neither overshadowed Porsche nor appeared outdated.

Motoring journalists were instantly won over by its powerful V8 engine with 237lb/ft torque and body-hugging profile, winning them over enough so it could receive the European Car of the Year award in 1978.

Still today, the 928 remains one of the most advanced cars ever created. When first released in 1979, its S model featured a 2mm overbore that increased V8 displacement from 4.7 to 5.74 litres for more than 300hp; later increases in compression ratio and introduction of electronic fuel injection pushed that figure beyond 310hp.

Though not as quick or luxurious as its rivals, such as Ferrari F430s or Mercedes S-Classs, Porsche 928 sports cars still provide enjoyable driving experiences for many people. As with most older vehicles however, their parts will start wearing down over time; therefore it is imperative that regular maintenance be conducted in order to preserve its life as much as possible.

One of the most crucial steps you can take is to regularly inspect the condition of your interior. Things such as door seals, window rubber and carpeting may wear down over time; to maintain optimal condition it is wise to check them and replace any worn parts as soon as they wear out. Also important are keeping an eye on electrics like sensor cables and ground straps which may become damaged from heat and corrosion over time.

Restoring the Seats

As part of our restoration, we begin with the seats. Porsche 928 seats are truly spectacular; combining classic leather with modern comfort features like power seating and climate control to provide an extraordinary driving experience. These features were considered luxury in their day, making driving one a real treat! In addition, this car has additional great features such as air-conditioning glove boxes which made driving it all the more special!

The front seat restoration kit for Porsche cars is designed to retrim both front seats. This DIY project does not require special tools; any moderately experienced home mechanic can complete this do it themselves task successfully. The kit contains everything needed, such as driver side and passenger side bolster covers as well as correction foam. Installation can be accomplished easily using no specific tools – making this an easy do it yourself task that any experienced mechanic can complete themselves!

Additionally, we retrim seats, reset SRS airbag modules and replace seat belt webbing – an absolute necessity for any 928 owner as seat belt webbing is notoriously fragile and likely to break after years of use.

As part of our comprehensive interior upgrade service, we also add new velour carpet to the entire car interior to enhance its overall look and feel. Not only is the new carpet much softer than its factory predecessor which was hard and scratchy; but its color coordinates perfectly with seats and door panels as well.

Finally, we add sound deadening to the car to reduce noise pollution and ensure your ride remains more comfortable. Sound deadening also contributes to noise pollution reduction by creating an audible noise barrier between door openings.

Classic 9 Leather Shop’s mission is to restore your vehicle back to its former glory, using authentic Porsche OEM materials and colors. Their services cover a range of leather and vinyl materials and colors to meet each vehicle’s specific requirements – such as Alcantara ultrasuede, domestic leather or even contrasting seam colors!

Restoring the Door Panels

Restoring classic Porsche 928s can be expensive, particularly if done professionally – including fresh paint and interior upgrades. In order to be financially feasible, such a project should only be undertaken if most of the work can be performed by yourself.

That’s where this guy comes in; by taking off the door panels he can access all those hard-to-reach areas such as fixing door handle mechanisms that often break easily on these cars.

Replacement rubber weather stripping and sound deadening material should also be installed at this time, to give your car an improved smooth feel when opening and closing its doors, and also to make driving quieter overall.

Restoring the armrest is another essential aspect of this job. In order to do this, remove the plastic trim piece that covers the perimeter of the opening for air flow from dash to armrest and access to a screw that holds armrest in place that can be easily unbolted using knife’s edge.

As part of your routine maintenance routine, it is also wise to inspect and clean the armrest in search of broken parts that need to be replaced. Over time, these components often break due to age and wear; without replacement they may eventually droop loose from their connection on the door panel and fall away completely – although this repair should be simple for anyone with basic mechanical knowledge.

Restoring the Dashboard

An easily overlooked part of any classic Porsche 928 is its dashboard, but adding a dash cover can instantly update its interior. There are various colors to choose from and they can even be custom tailored specifically to fit your car – using silicone adhesive, there is no need to remove or install an entirely new dash!

The Porsche 928 GTS

The Porsche 928 GTS was the ultimate 928 and was only produced towards the end of its 17 year run.

The GTS stands out from its late 928 models by featuring flared rear wings, full red light panels and 17” Cup wheels. MotorWeek especially enjoyed driving it.

340bhp

The 928 was an iconic design statement, its recessed pop-up headlights and expanse of glass around its tail creating an air of space age grandeur. A classy yet elegant car, offering rear engine enthusiasts something different from what the 911 could offer at that time; combined with its impressive refinement and pedigree made it incredibly desirable; with prices beginning just over 20,000 euros and top examples such as this low mileage blue GTS nearing 50k euros it proved hugely popular with drivers worldwide.

It’s easy to see why it was such a hit: this car can accelerate with incredible force. Just press down on the throttle pedal and watch as your car transitions from being an effortless cruiser into something much more urgent, complete with an engine that sounds more like an American V8 than those found on modern BMW or Jaguar cars – surely one designed for racing?

At the 1991 Frankfurt Motor Show, the GTS received some updates to ensure its debut with a larger 5.4-litre engine that produced 345bhp. There were also styling adjustments such as adding body-coloured wings and new 17″ alloy wheels; its equipment levels remained generous – featuring everything from an advanced Blaupunkt stereo system and climate control to power adjustable seats and power adjustment features.

However, sales dwindled so significantly that Porsche decided it had reached its sell-by date and discontinued this long-wheelbase 2+2 coupe in 1995. Since then however, there has been an enormous surge of enthusiasm surrounding this iconic German machine, making the GTS an excellent candidate when searching for used vehicles.

Maintenance costs for this car reveal its high running costs when things go wrong, so prior to making your purchase it’s essential that you inspect and read all warranty documents carefully. Furthermore, before handing over the keys you should speak with an independent specialist and identify any potential work needed before handing them back over to the dealer.

5.4-litre V8

Contrasting with its 928 cousin’s image as an effortless cruiser that covers continents like flies, this GTS stands out. A true sports car, its dogleg-shift Getrag five-speed manual gearbox channels all 1620 kg of its power through Porsche’s limited slip differential and unleashing it with just one throttle tap to race down Oxfordshire’s damp spring lanes at high speed.

This engine is identical to that found in any GT, but has been altered to displace 5.4 litres by overbore and fitted with pistons which increase compression from 9.5:1 to 10.0:1, creating an output rating of 240 horsepower (177hp in North America).

This 1989 GTS first registered in the UK was purchased in 2017 at only 140k miles by its current owner – who promptly had it serviced by an official Porsche dealer, including a complete timing belt service, Continental Extreme Contact tires installed, replacement of clutch slave and master cylinders, rotor replacement, caliper replacement and full four-wheel alignment service by an approved Porsche dealer. Additionally, a Shark Tuner performance chip, 18″ Carrera III wheels with power adjustable front seats as well as Blaupunkt CD stereo music have also been installed into this GTS car since.

This vehicle still possesses its original delivery materials – including its original delivery folio and factory sales literature, VINnalytics build report, and Porsche Certificate of Authenticity – and comes complete with full main dealer/specialist service history to deliver years of excitement!

This is an unparalleled opportunity to own an iconic and desirable successor of the Porsche 911: the Porsche 996 GTS. While prices have seen significant increases since 2010, standard GT’s can still be purchased for around PS20,000; manual examples will cost more. We often see leggier, fully-historied automatic GTS’s available for under PS90,000. Though perhaps less iconic, these cars present unmissable opportunities; so if this car interests you please get in touch for more details!

Spectacular handling

Porsche took its reputation for roadgoing GTs a step further with the 928 GTS, adding body-coloured rear wings, increasing V8 capacity from 5.0 to 5.4 litres and upgrading brakes, suspension and passive-steer ‘Weissach’ rear transaxles as part of a bold upgrade plan that resulted in class-leading speed, power and handling characteristics – bold moves but well rewarded – making the GTS an essential model in its class.

Light yet responsive steering points the car precisely into corners, even on B-roads with bumpy surfaces, providing vertical movement over bumps while remaining unimposing; an attribute made more evident by its 17in alloys wrapped with 255/75R17 tires.

Traction is enhanced by its 50:50 weight distribution, making the car far more versatile than a BMW 850i with its restrictive 225/255-tyre fitment. Autocar measured an acceleration time to 60mph of 5.4secs and top speed of 168mph – figures enough to challenge modern 911s.

And as you push the GTS harder and harder, its performance only grows more impressive. Brakes don’t fade, transmission remains light and precise and engine has plenty of character compared to more modern flat-plane crank units which feel more like two four cylinder units stuck together.

With just 14,300 miles on its odometer, this Porsche 911 Carrera S is in outstanding condition. It comes equipped with its original Certificate of Authenticity as well as service invoices dating back to 1996 as well as recent cambelt replacement.

It was designed as the embodiment of old enthusiast’s dreams: a sports-racer made suitable for daily driving. Although its advanced abilities did not appeal to traditional 911 buyers at first, its advanced abilities eventually won over Generation Xers who have recently experienced this car for themselves with fresh eyes. A true engineering icon and incredible value, only madmen would pass up such an offer at this price!

Comfort

The Porsche 928 GTS marked their inaugural effort at crafting a large displacement, luxury front engine rear wheel drive grand touring car. Their inaugural effort proved so successful that it earned them the 1978 European Car of the Year Award, outstripping mainstream hatchbacks and sedans from major European manufacturers in terms of comfort and power. This success served as an important marker of progress for Porsche, showing their innovation was far ahead of its contemporaries at that time.

Porsche also used this milestone to diversify their market reach and model lineup by targeting buyers not limited to sports car enthusiasts. This allowed the company to broaden their market presence and expand product options.

This 1995 928 GTS, built on December 12th 1994 and featuring Black Metallic paint over Marble Grey leather interior is equipped with am/fm radio/cassette player with six CD changer, auto climate control system and Porsche Crests on wheel caps, as well as power seats with lumbar support for driver. Furthermore, its Certificate of Authenticity lists other options including AM/FM radio/cassette player with six-CD changer, auto climate control, six CD changer changer, six CD changer changer player for six CD changer, power seats with lumbar support for driver and an automatic transmission system.

Inside, the cabin feels almost sterile in order to maximize speed. This was intentional, and works well with the car’s sleek shape. Features of note include flat door panels with classic RS fabric latch pulls; an amazing three-spoke steering wheel which obscures part of the speedometer arc; and hardshell bucket seats suited for those attempting monastic-like control over their beer and chocolate intake.

With its powerful 5.4-liter V8 and 345 horsepower, the 928 GTS can accelerate from zero to 60 miles per hour in only 5.7 seconds! Plus, its sleek shape allows it to easily cruise the old N7 autoroute from Paris to Monte Carlo casinos without breaking a sweat!

While purists might still favor a 911, Porsche has made significant efforts with the 928 GTS to craft an affordable GT car designed for long distance driving and comfortable comfort. It provides an unrivalled combination of style, performance and refinement not found with other premium manufacturers’ offerings today; thus making this rare breed worthy of being appreciated and preserved for future generations to enjoy.

 

 

Porsche 928 Turbo Kits

John purchased his first 928 and immediately started looking into ways to increase power – using stroker, supercharging or turbocharging options were all possibilities.

With this kit installed on its engine, a factory 928 can produce over 550 rear wheel horsepower at stock pressure levels while having an extremely broad and strong powerband – no doubt contributing to making the Porsche 928 an impressive design statement!

The Engine

The Porsche 928 features not only a powerful V8 engine but also an innovative rear-wheel steering system to enhance stability on long trips over mountain roads, making handling easier during races – one reason it has such fast acceleration from zero to 60.

The initial 928 was intended to be more practical than its Porsche counterpart, featuring spacious back seats that made it suitable for families. Furthermore, its aerodynamic design improved fuel economy. A front-mounted turbocharger further increased performance. Overall, the first generation 928 was an enormously successful model that saw further sales through subsequent generations.

Porsche introduced an all-aluminum 928 S in the 1980s. It featured new front and rear bumpers, larger brakes, 17-inch wheels, faster acceleration than its predecessor and even had an all-aluminum exhaust and upgraded interior – becoming especially popular across North America thanks to Brumos Racing Team’s use.

Porsche made additional modifications to the 928 during production, such as making its front fenders look more like those found on its sister model the 911 and adding hidden pop-up headlights that stowed away into its body when not needed; these features were made available through Porsche Exclusive as option XC1; however only around 10 cars were ever produced with this feature.

In 1984, Porsche sent an all-aluminum 928 to Daytona’s 24 hours race and told its three drivers Richard Attwood, Vic Elford and Howard Meister not to modify their car in any way. While in practice they found their vehicle unstable on Daytona’s steep banks; when they tried adding a rear wing as part of a modification attempt; Porsche refused.

Porsche introduced the 5.4-litre 911 GTS as a replacement to the 928 S4 in the early 1990s. Equipped with the same engine as its SS counterpart, this sports car featured air conditioning, leather-clad dashboard and special front/rear spoilers plus sport exhaust system for optimal performance on tracks or long trips alike. The GTS proved especially capable against rival cars on track while still remaining highly cost effective on long journeys.

The Intake

The Porsche 928 is a front-engine, water-cooled V8 sports car designed specifically for street use but capable of competing in motorsport events as well.

The original first-generation cars were produced between 1978 and 1986. After 1979, these vehicles were modified with front and rear spoilers to give a more angular appearance; additionally, a wider body with an attractive shark nose profile was also implemented.

1984 also brought with it an upgraded powertrain: the 928 got its new V8 engine rated at 291 HP (220 kW; 300 hp), up from its earlier model’s 240 HP (173 kW; 177 hp). Over its 18 year production run, numerous cosmetic and mechanical upgrades were introduced into production of this iconic vehicle.

Early versions of the car ran the risk of overheating due to lack of cooling fins on cylinder heads. To combat this issue, Porsche engineers experimented with various combinations of cooling fins and heat sinks as well as using an innovative oil cooler with internal bypass cooling capabilities to cool the engine.

Porsche eventually settled on the design that would become production models. Their cooling system was upgraded to include a larger radiator, while oil pump modifications were made. A dual distributor ignition system was introduced as well to enhance performance and reliability.

One intriguing modification to the original 928 was its PDK double-clutch transmission, developed using technology used in Porsche racing cars. Unfortunately, however, even with these improvements the 928 was still not fast enough to compete against modern sportscars.

At one time, speculation swirled that Porsche would release a 928-inspired turbo car; these rumors were eventually disproved; however, second-hand models remain popular due to their good value and high resale prices; making them ideal choices for buyers seeking both thrills of driving fast sports cars while making wise financial choices. To protect your investment the best way possible it is essential that you purchase as high quality vehicle as you can afford.

The Exhaust

A Porsche 928 turbo kit should include custom intake and exhaust components designed to extract maximum performance from its engine, including custom intake and exhaust pipework, to increase horsepower and torque dramatically. A boost controller should also be included to keep engine operating within safe parameters – essential due to turbo pressure which puts undue stress on engines which could overheat, potentially overextending oil reserves, or running dry of oil supply. A boost pressure sensor is installed as part of this kit to monitor engine operating status, shutting off pump when necessary to protect against overheating engines from overheating conditions caused by turbo-pressure from its exhaust pipes allowing maximum engine potential from its turbo.

Porsche 928 engines are unparalleled in that they use two turbochargers to compress air before entering the combustion chambers, operating serially to maximize performance. Cooled by ambient air prior to entering turbochargers, compressed in a compression stage until producing high-pressure gases before feeding this combination to individual cylinders through a dedicated, custom plenum box.

Porsche introduced an upgraded 928 called the S model during the late ’80s. While maintaining similar bodywork to its standard counterpart, this version featured a revised 4.7 L engine capable of producing 221kW (296 HP). Unfortunately, this upgrade only made available briefly in North America before becoming less desirable than its original version.

As part of its special edition model, a carbon fiber Turbo badge was specially crafted and placed on the rear of this vehicle. Furthermore, an exclusive front spoiler and set of 16-inch flat disc wheels were added as special touches that make this model easily distinguishable from regular production cars.

Porsche introduced the 928 to the world in 1978 as an exotic departure from its road and race-oriented creations such as the 911 and 356 models. For instance, this was the first time they used a V8 engine production car; designed to compete against notable Grand Tourers such as BMW M1 and Datsun 280Z models.

The Tuning

The Porsche 928 is an exquisite sports/GT car, and its 18 year production run was marked by many modifications and upgrades that further refined it. While its initial sport/GT car status made it great from its debut, adding forced induction can take it even further; both engine and body were regularly tuned up for greater responsiveness and speed, with turbo kits making this truly special vehicle even more desirable.

First on the agenda was installing a Porsche engine into the chassis, which proved more complicated than originally anticipated. Ferdinand Piech wanted a smaller-displacement Porsche 4.8 litre engine but this decision was altered at his request in favor of using the larger Volkswagen EA827 unit found in Lamborghinis like Gallardos; perhaps due to Porsche board members wanting to maintain some distance between their organization and Volkswagen while maintaining the 928 as an independent entity.

Porsche engineers used their increased horsepower to develop a new cooling system and enhance lubrication that allowed for faster yet more reliable vehicle. This step forward from earlier cars remains one of the main contributors to its success today.

Porsche engineers Wolfhelm Gorissen and Manfred Bantle used an unusual test car – an Opel Admiral equipped with components from a Porsche 928 suspension – in order to test out their new turbo-charged car, leading them down a racetrack while collecting data for analysis – this eventually gave rise to the concept for creating the GT version of this vehicle.

The 928S was initially unveiled in Europe during 1982’s summer season; it would later reach North American buyers as late as 1983. While providing similar performance to its European counterpart, North American customers received front and rear spoilers, larger brakes, carbon fiber Turbo badge on the rear as well as an optional “Competition Package” featuring sports exhaust and Bilstein shock absorbers for an enhanced driving experience.

The Stage 1 kit is the ideal upgrade for 928 owners looking for an immediate increase in horsepower and torque without compromising drivability or reliability. This upgrade kit contains a high-quality German manufactured cast aluminum/stainless steel supercharger, an intake manifold designed to fit seamlessly in the factory engine bay without needing modifications, and high flow exhaust with maximum flow without compromise to sound quality – producing up to +140 HP and +63 TQ gains across the RPM spectrum.
