A modular engine is built around four modules:

the intake module

the cylinder head module (RH)

the cylinder head module (LH)

single overhead camshafts

two valves per cylinder

sequential multiport fuel injection (SFI)

aluminum cylinder heads (6049)

cast iron, 90-degree V-shaped cylinder block
