Brian Crower Mitsu 4G63/ 7 Bolt Stroker Kit-94mm Billet Crank-BC625+ Rods (6.141in) Custom Pistons

This Brian Crower stroker kit is built for the 4G63 7-bolt engine found in your 1993-1999 Mitsubishi Eclipse, 1993-1998 Eagle Talon, 1993-1994 Plymouth Laser, and 2003-2006 Mitsubishi Lancer. It's designed to increase engine displacement from the stock 2.0 liters to 2.1 liters, giving you more power potential and torque across the entire RPM range. If you're looking to build a more potent engine for track use or serious street performance, this kit is a solid foundation.

At the heart of this kit is a 94mm billet crankshaft. Billet steel is incredibly strong and resistant to flexing, which is crucial when you're pushing more power through the engine. This crankshaft is paired with Brian Crower's BC625+ connecting rods. These rods are forged from high-strength steel and feature ARP fasteners, known for their reliability under high stress. The kit also includes custom-profiled pistons designed to work with the new crank and rod combination, optimizing compression and combustion. The rod length is 6.141 inches, a common choice for this application that balances stroke with piston speed.

When installing a stroker kit, it's important to ensure all components are balanced precisely for smooth operation and longevity. This kit is a significant upgrade for anyone serious about extracting more performance from their 4G63 engine. Remember that this kit is not CARB approved and cannot be shipped to California. You'll want to consult with your engine builder or refer to Brian Crower's installation guidelines for specific assembly and balancing procedures.
