AMS have successfully applied their race-winning experience to the GT-R’s VR38 to bring you the paramount in engine programs. The Alpha 3.8 is a race-proven power plant that uses only the best off-the-shelf and custom designed Alpha spec. components. Combine that with the latest in machine and assembly practices and you are assured only the best! To improve the output of your VR38, they raised the compression ratio to increase horsepower throughout the power-band. This increase also produces more low-end torque which reduces turbo lag and improves boost response. AMS worked closely with Manley to specially design engine components worthy of the Alpha program. The Alpha Extreme-Duty Pistons feature improved oiling characteristics, PTFE coated skirts for reduced friction and extra thick ring lands for added strength and other proprietary features that make them Alpha capable. The Alpha 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, 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. When you choose an Alpha engine, you are investing in the knowledge gained from assembling thousands of race engines over the past 10+ years. With more than 200 Victories in Motorsports over the last 3 years alone, it is clear that AMS is the only choice for your car! Included in their 3.8 Crate Engine are the Alpha Camshaft Package and Ferrea valve spring and retainer kit. With this combination, they balanced the flow at low, mid and high lift to achieve the most effective and broad power curve. That means the most power for you off the stop light, at the strip, or on the road course and the confidence to leave the competition in your dust! If you are looking to take power to the next level you can even upgrade to their Alpha CNC Race Ported Cylinder Heads. The Alpha 3.8 Crate Engine comes complete and sealed from valve covers to oil pan. The engine is timed and the front covers installed so all of the hard work is already done for you making your engine swap a bolt-in affair.
