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 <li>Same bore pitch (82.5mm - 90mm - 82.5mm) <li>Lighter casting <li>Similar head gasket <li>E15 is overall shorter to fit transverse applications (FWD) <li>Crossflow head with semi-spherical chambers improves on A15: HP and torque are both up 3% <li>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) </ul>
