AMS Stage 2 Short Block - EVO X

The AMS Mitsubishi Lancer Evolution 10 Stage 2 Shortblock is the ultimate solution for high horse power reliability. We use 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!

By utilizing ductile iron sleeves and skirt coatings on the pistons we achieve maximum reliability for your 4B11 build.  Each block is precisely machined to accept AMS’ proprietary 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.

All our engines are hand assembled at AMS using the same care as the engine in our 1142 awhp, 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.
