Brian Crower Stroker Kit (Econo Rods) Mitsubishi 4G63

The Lancer Evolution or "Evo" is Mitsubishi's flagship sports car. Based only on the unibody of the domesticated Lancer sedan the Evo is a rally inspired, turbocharged, all wheel drive, durable and finely tuned automobile. The number designation of the model is most commonly a roman numeral. Evolution models prior to version V were the officially approved models for Mitsubishi's efforts in the World Rally Championship's Group A class and SCCA Pro Rally Championship. In order to follow these rules, the Evolution is based on the same platform as the Lancer, but is much more powerful and the only major part in common between the Evo and the Lancer is the unibody. Nine street versions of the Evolution have been produced from 1993 up to today. Evolution versions VI, VII, VIII and IX did not need to meet WRC homologation requirements. The Evo was originally intended only for Japanese markets but demand on the 'grey import' market led the Evolution series to be offered through limited type-approval in the United Kingdom and in various European markets from around 1998 (Evo V-VI). Mitsubishi decided to export the eighth generation Evolution to the United States in 2003. The Lancer Evolution VIII is the first Evolution to come to the United States. These cams are not interchangeable with the traditional 4G63 found in the US based Eclipse and earlier Evo models.

The Mitsubishi Eclipse has been in production since 1989 and is produced solely for the United States and Canadian market, where it has also been built as the Eagle Talon and the Plymouth Laser through Mitsubishi Motors Corporation's close relationship with the Chrysler Corporation (now DaimlerChrysler) known as Diamond Star Motors, or DSM. The first generation Mitsubishi Eclipse was available in four trim levels in both FWD and AWD models, but all were equipped with the 4G63 engine, most in the turbocharged (4G63T) variety. The 1st Gen engine (6 bolt crank) was used from 1989-1992. The second generation engine (7 bolt crank) was introduced in 1993, but used in the 1st Gen chassis through 1994. In 1995 there was a major update in styling, including a convertible model called the Spyder. The 7 bolt, 4G63 engine was used until 1999. Both the 1st Gen and 2nd Gen 4G63 engines use the same camshafts, however do not confuse the 4G63 engine with the non-turbo, 420A Chrysler engine that was used in the base FWD Eclipse from 1995 to 1999.

The BC stroker kit for the Mitsubishi 4G63 engine platform incorporates a 102mm stroke, 7 bolt crank. Depending on bore size that you decide, the BC kit will take you up to a 2.4L with 86mm bore.
