Fiat 126P with a 2.3 L H4

This Fiat 126p was built in Poland and features a VW 2.3 L H4 engine. These small cars originally came from the factory with a 0.6 L straight-two engine. The engine features ported heads, forged internals, increased compression, and twin Weber IDA carburetors. Running off E85 fuel the engine produces 211 horsepower and 237 Nm (174 lb-ft) of torque. That might sound small but for a car that weighs so little it is enough to move this car pretty well and lift the front wheels off the ground.
