4B11 Evo X Crate Engines

The Mitsubishi Evolution X 4B11 is one of our engines we rebuild here at Synergy Engines .   We do not offer core exchanges, and will rebuild your supplied engine core for the build.    With different blocks , strokes, and rod length options, there are many ways to get creative with this popular platform.  The 4B11 is a DOHC Cylinder head with Solid Cam Followers, making this build more labor intensive than most.
