Porsche 928
The Porsche 928 was a sports-GT car sold by Porsche AG of Germany from 1978 to 1995. Originally intended to replace the company's iconic 911, the 928 attempted to combine the power, poise, and handling of a sports car with the refinement, comfort, and equipment of a luxury sedan to create what some Porsche executives thought would be a vehicle with wider appeal than the compact, quirky and sometimes difficult 911.

Porsche 911 GT3
In GT3 configuration, this so called "split" crankcase (meaning the parting line of crankcase is on the crankshaft centerline) uses, instead of a fan and finned cylinders, separate water jackets added onto each side of the crankcase to cool banks of three cylinders with water pumped though a radiator. Thus, the GT3 engine is very similar to the completely water cooled 962 racing car's engine, which is also based on this same crankcase. The 962 differs, however, by using 6 individual cylinder heads while the GT1/GT3, like the air and water cooled Porsche 959, uses 2 cylinder heads, each covering a bank of 3 cylinders. The GT3 engine could thus also be thought of as similar to a 959 engine, but with water-cooled cylinders.
Up to early model year 2004 GT3 production, the basic casting used for the crankcase of the GT3 was exactly the same as the air-cooled engine and one could see the "964" casting number on the bottom of the crankcase and areas normally machined in the air-cooled application that are not machined for use in the water-cooled application. The crankcase casting was changed in mid-2004 to a "996" casting number crankcase to eliminate these external air-cooled remnants, but internally it is the same.Friday, July 8, 2011

Porsche Boxster
The Porsche Boxster is a mid-engined roadster built by Porsche. The Boxster is Porsche's first road vehicle since the 550 Spyder that was originally designed as a roadster. The first-generation Boxster (the 986) was introduced in late 1996 as a 1997 model; it was powered by a 2.5 litre flat six-cylinder engine. In 2000, the new Boxster S variant was introduced with a larger 3.2 litre motor, and the base model received a more powerful 2.7 litre engine. In 2003, styling and engine output was upgraded on both variants. In 2005, Porsche unveiled the new generation of Boxsters: the type 987. The 987 is more powerful than its predecessor and featured styling inspired by the Carrera GT. Engine output increased in 2007, when both Boxster models received the engines from their corresponding Porsche Cayman variants. In 2009, the Boxster models received several new cosmetic and mechanical upgrades, further increasing engine output and performance. Production of the 986 began at the former Porsche 928 facility in Stuttgart, Germany in 1996. Valmet Automotive also manufactures Boxsters under contract to Porsche at a facility in Uusikaupunki, Finland. The Boxster was Porsche's biggest volume seller from its introduction in model year 1997 until the company introduced the Cayenne sport utility vehicle in model year 2003. The Boxster's name is a portmanteau of the word "boxer", referring to the vehicle's horizontally-opposed or "boxer" engine, and the word "roadster", referring to the vehicle's two seat capacity and convertible top.Porsche Boxster Review - Kelley Blue Book
