STROKER KIT - Mitsubishi 4G63 (6 bolt), 102mm 4340 Forged Crank, BC625+ Rods, Custom Pistons
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.
