can be altered, therefore the displacement as well, just by adding a different set of cylinder liners. The engine also features an aluminum cylinder head with
double overhead camshafts and
variable valve timing.
1.8
The 1.8L I-4 is a
dual overhead cam (DOHC) inline 4-cylinder gasoline engine capable of and of torque.

Tigershark
The Tigershark engine family is the name for the next generation of World Gas Engines with work starting on them shortly after acquisition of Chrysler. The major differences compared to the first generation are the updated valvetrain and intakes.
2.0
The 2.0 L Tigershark DOHC inline 4-cylinder gasoline engine has
