E15 SOHC

Will the new E-series heads might fit on the A12 engine? Note that the 1982 E15 engine design is based on the A15 engine:

  • Same bore & stroke
  • Same bore pitch (82.5mm - 90mm - 82.5mm)
  • Lighter casting
  • Similar head gasket
  • E15 is overall shorter to fit transverse applications (FWD)
  • Crossflow head with semi-spherical chambers improves on A15: HP and torque are both up 3%
  • The E15 uses a jackshaft "in the area where the camshaft is mounted on the A-series engine" to drive the fuel pump and oil pump (the distributor is driven off the front of the cam)
