Abacus Automotive & Machine Shop Services is located in Virginia Beach, Virginia at 1372 Baker Rd. in the Airport Industrial Park. Formally known as Phase One Machine Shop, we are the original import performance shop in the Tidewater area. Established over 20 years ago, Abacus began building motors for British sports cars participating in SCCA and SVRA events. That experience carried over to the development of Nissan 4 and 6 cylinder engines for SCCA GT-2 and GT-3 events culminating in numerous national championships.
