AMS Alpha 4.0 Big Bore Crate Engine Package – Nissan GTR 09+ (R35)
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 block is precisely machined to accept Darton ductile iron sleeves. Once installed the block is then final bored, honed and align honed to ensure perfect clearances and fitment. The finished product allows for higher cylinder pressures and added strength and rigidity to the block.
AMS worked closely with JE Pistons and Manley Rods to specially design engine components worthy of the Alpha program. The AMS Extreme-Duty Pistons feature improved oiling characteristics, Teflon coated skirts for reduced friction and extra thick ring lands for added strength and other proprietary features that make them Alpha capable. The AMS Extreme-Duty Connecting Rods utilize large 7/16 ARP 2000 bolts (22% larger than stock) for added durability and peace of mind.
To further improve the VR38 platform, each block deck is machined to receive a copper o-ring to establish a better combustion seal. Every Alpha 4.0 Race Engine is then precisely balanced, blueprinted and hand assembled to AMS exacting standards. Before assembly each block is checked for correct dimensions, cylinder bore, mains, block flatness, etc to guarantee you get the best foundation for your new engine.
Included in the Big-Bore Crate Engine are the Alpha Cylinder Heads and Camshaft Package. The flow at low, mid and high lift has to be balanced a certain way to achieve the most effective power curve. That means the most power for you off the stop light, at the strip, or on the road course. The Alpha Cylinder Heads utilize the latest Ferrea Competition Plus components. Their valvetrain components are made from exotic alloy materials to with stand high boost and RPM’s. In addition, our Engineering Team developed a proprietary modification that provides a better combustion seal which is applied to every set of Alpha Cylinder Heads. To top things off the Alpha Camshafts work in harmony with the cylinder heads to offer you the most useable power throughout the entire power band.
