    AMS Mitsubishi Lancer Evolution X & Ralliart Sleeved Block

    The AMS Mitsubishi Lancer Evolution X / Ralliart Sleeved Cylinder Block is the perfect foundation for your high horsepower 4B11 build! This is the same block found in the 2009 Redline Champion AMS Time Attack EVO X (TA-X) and the 2009 North American Rally Champion ACP Rally EVO X! During the 2009 season, we were able to extract 850 horse power from this race-proven power plant – setting the world horsepower record for the EVO X in the process!

    Each block is precisely machined to accept the latest Darton MID (modular integrated deck) ductile iron sleeves. The sleeves are pressed into the block to sit atop a machined step to ensure they will not sink during engine operation. The block is then final bored & honed using a torque plate to ensure perfect clearances and fitment. The finished product allows for higher cylinder pressures and added strength and rigidity to the block.

    Please Note: If you do not wish to send in a core to have machined a core charge for a new OEM 4B11 block will apply. You are also given the option of choosing any bore size between 86mm and 90mm based on your needs.
