The 2.4L stroker combines a stock 2.4L 4G64 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 King or ACL Race Series main and rod bearings and ARP 207-5401 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!
