| Litchfield/Powerstation Type 25 (2007) The new Type 25, like the previous Type-25, used a modifed EJ257 block but it was built by the US arm of Cosworth. They used Cosworth’s own forged pistons and conrods balanced to within 0.5 grams. A modified STI crankshaft and STI engine casing were used and the 'short' engine was assembled by hand. This ‘short’ engine was sent to Litchfield to be finished and fitted by PowerStation. Cosworth honed, big-valve, ported cylinder heads and cams were used and the engine was installed into a 2007 Japanese specification Spec C. The engine produces 415 bhp (309 kW) and 420 lb·ft (569 N·m), for a power/weight ratio 1 hp higher than a Porsche 997 Turbo. The car could be ordered with an optional Powerstation developed Porsche ceramic brake system. http://www.type-25.co.uk/exterior.asp#5 | |
