In March 1998, Mitsubishi issued a recall (bulletin 98V069001) for all 1990-1998 Mitsubishi Eclipse GSXs citing, "Lockup of the transfer case can occur due to insufficient lubrication.

The bolts refer to the number of bolts on the flywheel that connects to the crankshaft. Beginning in May 1992, Mitsubishi revised the engine to a 7-bolt design. The engines built from 1989 through April 1992 have 6-bolt motors.

The turbocharged 4G63 engine received an internal update during the 1992 model year. The turbocharged version of the 4G63 (sometimes referred to as the 4G63T) has a lower compression ratio of 7.8:1 and oil squirters under the pistons for better cooling from extra heat created by forced induction. The 4G63 has an iron engine block with an aluminum cylinder head and is equipped with two balance shafts. The 4G37 and 4G63 engines are gasoline inline-fours. AWD models have a different transmission which includes a limited-slip center differential and output shaft for a transfer case, which drives the rear differential (also available as limited-slip) and half-shafts.

The basic driveline layout of the Eclipse is a transverse-mounted 4-cylinder Mitsubishi 4G37 or 4G63 engine situated on the left-hand side of the car driving an automatic or manual transmission on the right-hand side. These models varied significantly in drivetrains and available options, and included some variance in appearance, as higher trim lines added different front and rear fascia panels and surrounding trim, with the GSX model getting a notably different styling package from the others. The automatic models were rated at 180 hp (130 kW) due to smaller fuel-injectors and turbocharger. However, 1991 and later years of both turbo models standardized on the 195 hp version 4G63T. This was for the purpose of offsetting the additional weight of the AWD mechanism (approximately 2,930 lbs Vs 2,570 lbs GVW). * The 1990 GS Turbo with a manual transmission was rated at 190 hp, whereas the 1990 GSX with a manual transmission was rated at 195 hp (145 kW).

They were built during Mitsubishi Motors' close relationship with Chrysler Corporation. The first two generations (1G and 2G) share the automobile platform and parts with the rebadged Eagle Talon and Plymouth Laser captive imports. A convertible body style was added during the 1996 model year. The Mitsubishi Eclipse is a sports car that was produced by Mitsubishi in four generations from 1989 until 2011.
