[edit] B16B (Type R)


  • VTEC
  • Found in:
    • 1997-2000 JDM Civic Type R[EK9]
      • Displacement: 1,595 cc (97.3 cu in)
      • Compression: 10.8:1
      • Bore: 81 mm (3.2 in)
      • Stroke: 77.4 mm
      • Rod/Stroke ratio: 1.84:1
      • Rod Length: 142.42 mm (5.607 in)
      • Power: 185 hp (134 kW) @ 8200 rpm & 110 ft·lbf (155 Nm) @ 7500 rpm
      • Redline: 9200 rpm
      • Transmission: S4C With LSD
      • Vtec engagement @ 6,000 rpm

  • Note: This engine uses the same block as the Integra Type R, which is taller than the B16a block, but with a crank the same stroke as the b16a. It uses longer rods to accommodate for this, which is why the Rod/Stroke ratio is higher than a standard B16. It is basically a 'Destroked B18C Type R engine'
Rod/Stroke ratio is at 1.84 and capable for spinning up to 10,000rpm safely.
