AMS Nissan GT-R Alpha 3.8 Race Short Block
We have successfully applied our race-winning experience to the GT-R's VR38 to bring you the paramount in engine programs. By developing AMS proprietary engine components we have engineered the strongest, most advanced VR38's available for your GT-R.
Big Benefits, No Compromises
To improve the output of your VR38, we 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.
The Perfect Combination for Alpha Power
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!
Not Your Standard Off-the-Shelf Rotating Assembly
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, PTFE 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.
Our Race Winning Experience Creates Higher Standards
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, block flatness, etc… to guarantee you get the best foundation for your new engine.
