AMS Mitsubishi Lancer Evolution X Stage 2 Crate Engine

The AMS EVO X Stage 2 Crate Engine is the ultimate solution for high horsepower reliability without the hassle of sending in your cores. AMS crate engine comes complete from valve cover to oil pan to timing chain and components to make installation as painless as possible. This package uses only the best products we sell and comes ready to drop right into your EVO.

This race proven power plant uses only the best off the shelf and custom designed AMS spec. components. Combine that with the latest in machine and assembly practices and you are assured only the best! This is the same block that powered the ACP Rally EVO X to the North American Rally Championship Win in 2009!

Each block is precisely machined to accept 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 using a torque plate, then 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.

To top off this package, included is the AMS EVO X CNC Ported Cylinder Head. Featuring the most advanced port design on the market, this head is fortified with +1mm oversized Ferrea valves and valvetrain components. The flow at low, mid and high lift have been optimized to achieve the most effective power curve, something overlooked by the competition who focus on peak numbers.

All AMS engines are hand assembled at AMS using the same care as the engine in our 1400 horsepower, world record holding AMS Drag EVO. Every motor is balanced, blueprinted and assembled to AMS’ exacting standards. Before assembly each block is checked for correct dimensions, cylinder bore, mains, block flatness, etc… to ensure you get the best foundation for your new engine. Every engine we assemble has a build sheet where tolerances, torque specs, and clearances are documented.
