AMS Performance VR30 Red Alpha Stage 2 Performance Engine
Tuner car builders love how the AMS Performance 4B11 Stage 2 2.0L drops directly into the Evo X chassis while simultaneously supporting massive turbocharged horsepower and torque upgrades.
- Stage 2 prep fortifies rotating assemblies
- 9.0:1 compression balances boost and timing
- 2.0L layout bolts to factory mounts
Description
Cylinder bore distortion and valvetrain float destroy high-boost turbocharged V6 motors during competitive road events. The AMS Performance VR30 Red Alpha Stage 2 Performance Engine eliminates structural block flex throughout this commercial long block repower. This 6-Cylinder 800HP power plant requires high-pressure oil feed line pre-priming before starting the motor for initial calibration.
Ductile iron Darton sleeves pressed into the A356-T6 aluminum block reinforce cylinder bores against boost pressures. A nitrided 4340 forged steel crankshaft connects to custom Carrillo forged rods and thermal-coated 2618 pistons. This AMS Performance engine core pulls a 12V 180A starter draw during high-compression starts. Dry weight is 355 lbs, measuring 26in length, 25in width, 27in height, with a 6.0 quarts oil capacity.
Key Features of AMS Performance VR30 Red Alpha Stage 2
Championship race teams buy AMS Performance VR30 Red Alpha Stage 2 Performance Engine packages to secure sustained podium results. Our industrial engine rebuild standard incorporates high-lift camshaft profiles and reinforced valvetrain components to eliminate high-RPM valve float.
- Ductile iron sleeves spun under centrifugal force provide extreme hoop strength under high boost.
- Rod and main journal oil clearances set at 0.0020in for sustained high-shear operation.
- Custom 2618 forged aluminum pistons feature ceramic thermal barrier crown coatings.
- Forged H-beam connecting rods utilize custom age-hardened rod bolts.
- Heavy-duty multi layer steel gaskets prevent fire ring extrusion at thirty pounds of boost.
- This VR30 commercial core receives full five-axis CNC combustion chamber profiling.
- Inconel exhaust valves withstand severe turbo anti-lag thermal cycles.
Dyno Cell Performance Verification
Dynamometer test logs show this VR30 long block engine delivers 800 continuous BHP and 720 ft-lbs of torque at 6400 continuous load RPM. Internal oil gallery pressure stabilizes at 68 PSI with oil sump temp held at 198°F under continuous boost tests. Exhaust gas temp tops at 1580°F at the turbo manifold runner. Cylinder compression values read between 185 PSI and 192 PSI. Crankshaft flange runout checks at 0.0002in TIR.
Field Installation Diagnostic Protocol
Twin turbo actuator linkages demand 7 lbs of linear pull force to guarantee stable boost pressure management. This specialized competition engine is not built for stock computer tunes, commercial delivery vans, or marine outdrives.
- Drain break-in motor oil after 500 miles or 15 track run hours.
- Inspect cold valve lash at 0.010in intake and 0.014in exhaust before initial runs.
- Torque heavy-duty head studs in four steps to a final 100 ft-lbs.
Racing Warranty Delivery Package
Backed by the elite AMS Performance assembly standard, this racing unit includes a 1-Year limited competition warranty. The crate houses the fully assembled long block, oil pan, front timing covers, valve covers, oil pickup tube, and signed dyno load sheet.
