Brian Crower Mitsu 4G63/Evo 7 Bolt Stroker Kit-94mm Crank-I Beam w/ARP2000 (6.141in) Custom Pistons

If you're looking to significantly increase the displacement and power potential of your 4G63 engine, a stroker kit is the way to go. This Brian Crower stroker kit is specifically designed for the 7-bolt 4G63 found in your 1993-1999 Mitsubishi Eclipse, as well as compatible Eagle Talons, Mitsubishi Lancers (2003-2006), and Plymouth Lasers (1993-1994). By increasing the crankshaft stroke to 94mm, this kit effectively raises the engine's displacement, which can lead to substantial gains in torque and horsepower when paired with supporting modifications.

This kit includes a high-performance 94mm crankshaft, custom-spec pistons designed to work with the new stroke, and strong I-beam connecting rods. The rods are fitted with ARP 2000 series bolts, known for their exceptional clamping force and reliability under high stress. The I-beam design offers a good balance of strength and weight for performance applications. Brian Crower is a well-known name in performance engine building, and their kits are assembled with precision to ensure proper fitment and function within the 4G63 block. This is a serious upgrade for anyone building a high-performance naturally aspirated or forced induction 4G63 engine.

When installing a stroker kit, it's crucial to ensure all components are balanced and that your engine block is properly prepped. This includes checking clearances and ensuring the block is clean and ready for assembly. You'll also want to consider supporting modifications like upgraded fuel systems, engine management, and potentially a larger turbocharger to take full advantage of the increased displacement. Always refer to the manufacturer's installation instructions for detailed guidance on assembly and torque specifications.
