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.
