AMS Performance have successfully applied their race-winning experience to the GT-R’s VR38 to bring you the paramount in engine programs. By developing AMS proprietary engine components they have engineered the strongest, most advanced VR38′s available for your GT-R. To improve the output of your VR38, AMS raised the compression ratio to increase horsepower throughout the powerband. This increase also produces more low end torque which reduces turbo lag and improves boost response. 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!
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. 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 3.8 Race Short Block is then precisely balanced, blueprinted and hand assembled to AMS’ exacting standards. Before assembly each block is checked for correct dimensions, cylinder bore, mains, and block flatness to guarantee you get the best foundation for your new engine.
