The 2.3L stroker combines a stock 2.0L 4G63 block with an OEM 4G64 crank or a 100mm crank and stroker pistons to increase displacement. If you need to spool a large turbo quicker or increase low-end torque that's lacking due to turbo lag this is the right choice!
All Modern Automotive Performance Stroker Build Kits come with ACL Race Series main and rod bearings and ARP main studs for your application. See below for our recommended choices of cranks, rods and pistons. When you choose a MAP Stroker Kit for your build, you're only getting the best based on our experience using these products on our race cars and the hundreds of engine builds we have done over the years!
Eagle 4340 Forged 100mm
Eagle crankshafts are forged from SAE 4340 steel, feature a non-twist forging, multi-stage heat treat process, stress relieving, shot-peening, and nitriding for superior strength and reliability in the most demanding applications. Each journal is micropolished to a 3 r.a. or better. A .125" radius is used to increase strength, so chamfered bearings must be used. These are the perfect choice for applications up to 1500HP. Approximate weight is 37 pounds.
