History of Litchfield Imports

Litchfield Imports has over 10 years experience trading in the best sports cars the world has to offer from Europe, America and Japan.

We first became known for selling the Japan−only Impreza Spec C which forms the basis of Subaru’s Group N Rally cars. These are significantly different from their UK/EU counterparts with a massive list of upgrades and changes. We are able to import these cars as we are the only company to have passed the relevant EU type approval tests. The car quickly became popular with customers and critics.

When Subaru made a change to the equipment level of the Spec C at the end of 2003 which meant the temporary loss of creature comforts like electric windows and air-conditioning we decided to create a Subaru with the same performance but still with these features. The Type−25 was born after we imported one of the very first 2.5 Litre American STI Imprezas.

History of the Type−25

Testing and development started on the Type−25 in late 2003 and was designed to address some of the issues raised with the Subaru STI Spec C as an everyday car. At the time, it appeared that the Spec C Limited, which had the luxury items of air−conditioning and electric windows, was only a short production run of 1,000. We were faced with only being able to sell the standard Spec C which without these items would not appeal to as many daily users. The concept for the Type−25 was to build a car that would showcase our products and would be as fast as the Spec C but be live−able day to day. The Type−25 has won many fans from journalists, engineers and clients alike.

PowerStation and Litchfield Imports have always been happy to put our workmanship and products up for critical scrutiny; F1 drivers, motoring Journalists, 160mph+ convoys along European auto routes at the height of Summer heat waves, up and down mountains, endless laps of UK circuits and test facilities have proved durability and quality. We feel that the Type−25 could not have been tested harder or more thoroughly. It is a testament to the careful way these cars have been built and the quality of the components used. We have regularly put the Type−25 up against not only its direct rivals but also the best the performance car industry offers. The positive words of respected journalists and also from experienced engineers and designers for some of the world largest performance car manufactures, have been fantastically rewarding.

The original Type−25 concept was a modest halo/showcase product with tiny sales expectations but has turned into a huge success with clients and a market place we had never even envisaged. These clients often already had a number of supercars in their collection including the likes of GT3s, Ferraris, Zonda and even McLarens. They would use these for special occasions or track days and a Cayanne or X5 for family duties. Many found the desire for something in between, a car that can be used daily, is practical, easy to live with and still a thrill to drive. The Type−25 fitted the bill perfectly.

The Type−25’s demand has allowed us to invest in new state of the art machinery and larger premises to service and develop our cars to an even higher standard. What started out as a dream of making a showcase product, has turned into a deeply−satisfying success that we look forward to continuing with the new car.

"Power through more than just displacement"

Original Type−25 engine details:

Subaru’s ubiquitous 2.5litre (EJ257) block first appeared in the 300bhp US STI then later in the Forester XT/STI and the new 226/276bhp European models. The EJ257 has been a necessary development for Subaru as they expand in world markets and have to tackle increasingly tough emission levels such as the enforced EuroIV emission standards in January’06. This 2.5 engine has allowed Subaru to meet these requirements whilst maintaining their high performance philosophy.

Although suitable for factory power targets the EJ257 has a number of short comings and limitations when looking to produce serious power. Early Type−25 development showed up weak points which were carefully addressed in the production versions. For example the Type−25 featured unique forged pistons fitted in the engines build process and these have proved extremely reliable unlike the standard hypoeutectic cast pistons that can reveal their brittle construction at higher power levels. The new Type−25 features pistons and conrods that are both stronger and lighter forged items than the standard Subaru parts, even the crank is checked and balanced before fitting.

One of the key reasons for basing the Type−25 on the Japanese Domestic Market (JDM) STI, aside from the higher chassis/equipment levels, is that the engine in the JDM car is much more advanced than the European or US versions. The Japanese car features a better cylinder head design which, with careful modification, allows far better flow rates than the European and even its standard EJ257 cylinder heads. The Japanese car also features larger ports which further improve flow and the cam shaft profiles are more aggressive allowing a larger power band. These improvements also allow better use of the Variable Valve Timing features which further broadens the engine’s mighty low down torque and high end power delivery.

Another key component to the JDM model’s outstanding power is the engine’s use of the Twin−Scroll turbo and equal length exhaust manifold. These essential parts allow the JDM engine to build boost far faster than the conventional Euro/US designs and virtually remove turbo lag and dramatically improve throttle response. The more efficient setup also allows the engine to rev higher and smoother than the older designs. The Type−25 takes the Twin scroll concept to a new performance level by using heavily modified parts whilst retaining all the JDM engine’s clever engineering.

The retention of the Twinscroll design allows the Type−25 to use larger turbo internals which still deliver ultra fast response whilst remain capable of supplying the 2.5 engine with ample air much higher up the rev range than the conventional Euro/US models can manage. The use of an advanced exhaust and improved inlet system allows the Type−25 to pump more air in and out of the engine whilst adhering to strict noise and emission legislation.
