2008-2015 Mitsubishi Lancer Evolution X / Ralliart
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, AMS was 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 new sleeves are machined to sit a few thousands above the rest of the deck surface allowing for a tighter sealing surface between the block and cylinder head. The block is then final bored, honed and align honed with ARP main studs installed to ensure perfect clearances and fitment. The finished product allows for higher cylinder pressures and added strength and rigidity to the block. You are also given the option of choosing any bore size between 86mm and 90mm based on your needs.
The price above includes the $2263 core charge for a new OEM 4B11 block.
If you have a good core to supply, please call to order as the machining will be only $1895.
