A Proven Foundation That Is Built To Last
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!
The Perfect Combination for Power and Durability
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!
Each Stage 2 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. Couple that with Manley pistons made with extra thick ring lands, skirt coatings and upgraded 9310 alloy wrist pins we achieve maximum reliability for your 4B11 rebuild.
To top off this package we include 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. For camshafts we use the AMS “TMP” Camshafts complimenting the ported heads with massive peak and low end power making great turbo spool up characteristics. The perfect combo for an unbeatable machine!
Race Winning Experience Creates Higher Standards
All our race engines are individually handcrafted at AMS using the same care as the ones found in our world record holding street and race cars. When you choose an AMS engine you are investing in the knowledge gained from assembling thousands of race engines over the past 15 years. With over 350 Victories in Motorsports over the last 7 years alone, it is clear that AMS is the only choice for your engine rebuild!
Just like our 2000+HP Alpha Omega GT-R, 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.
