1994→1995 Turbo Technics E 320

Now you’ve chosen to drive a Mercedes-Benz…
…why compromise your driving experience?
Supercar performance with all the benefits of a luxury limousine.

Outline technical specification

3 litre, 6 cylinder, 12 valve engine
Reduced compression ration, modified throttle body and plenum chamber;
additional engine management unit, working in conjunction with the standard electro-mechanical fuel injection system, to optimise fuel flow and ignition advance curve;
two additional fuel injectors;
twin Garrett T2 water cooled, pressure lubricated turbochargers;
Intercooler;
cast nickel iron exhaust manifolds linked to large diameter stainless steel exhaust system incorporating the standard catalytic converter.

3 litre, 6 cylinder, 24 valve engine
Modifications essentially as per 3 litre/12 valve unit with appropriate detail adjustments.
The catalytic converter cannot be incorporated within the exhaust system on models using this engine.
The 155mph speed restrictor is retained.

3.2 litre, 6 cylinder, 24 valve engine
As per 3-litre/24 valve unit except that a single large additional fuel injector is used and the additional engine management unit works in conjunction with the standard, all-electronic fuel injection system.
The catalytic converter is incorporated within the exhaust system on models using this engine.

Note: 98 octane Super Unleaded petrol is required with all the Turbo Technics turbo conversions.

Owning and driving a Mercedes-Benz is a special experience, born out of its renowned engineering and legendary build quality.
The marque, in all its guises, undeniably provides levels of refinement that are widely regarded as the benchmark for the industry.

Recognising the product’s huge reserves of durability, the UK’s leading turbocharger specialists, Turbo Technics,
has seized the opportunity to produce a unique high performance engine conversion applicable to both the 300 series and 3.2 litre E series models.

Whilst the primary objective was to offer supercar performance with all the benefits of a luxury limousine, retaining the inherent levels of refinement was considered a prerequisite.

The result is quite simply breathtaking. By concentrating on enhancing the standard engine’s torque delivery, as opposed to its outright power,
the conversions offer sensational low and mid range punch which permits effortless overtaking manoeuvres.
Throttle response is crisp and instantaneous, and drivability is in no way compromised.

The conversions call for no alteration in driving style or special procedures and, apart from the dramatically increased performance,
most drivers would be unaware that any form of modification had been carried out, unless they happen to notice the very discreetly placed components in the engine bay.

Even fuel consumption is unlikely to be adversely affected, although this naturally depends upon the driver’s ability to resist the temptation to use the electrifying performance at every opportunity
and in most cases catalytic converters can be retained where fitted.

All too often a well-engineered conversion is spoilt by the quality of the installation.
With their fine reputation at stake, Turbo Technics had no hesitation in appointing the long-established Mercedes-Benz dealer, Hughes of Beaconsfield, as its exclusive fitting agent.

Standard service intervals and routines remain unchanged, and the reliability of the installation is such that Hughes offer a 12 month, unlimited mileage guarantee with complete confidence.
The conversion applies equally to saloon, coupe and estate variants and, subject to engine condition, can even be carried out on vehicles having completed as many as 60,000 miles.

Hughes of Beaconsfield can also provide a wide range of ancillary equipment to complement the turbo conversion and thus create what is arguably the ultimate executive express.

The UK’s foremost motoring magazine, Autocar and Motor, probably summed it up best in their road test of the 3 litre 12 valve model:
“The Turbo Technics conversion works like a dream”.
