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 Alpha 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 Manley to specially design engine components worthy of the Alpha program. The Alpha Performance Extreme-Duty pistons feature improved oiling characteristics, moly coated skirts for reduced friction and extra thick ring lands for added strength. The Alpha Performance 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, every Alpha 3.8 Race Engine is then align honed, 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.
