LF 4 Cylinder Engine for Nissan Note E12

[starbwoy richie]

As subject says, would like to convert my gas car to cng but the engine must be 4 cylinders and mine is 3.
Anyone know if there are any 4 cylinder engine alternatives and rough cost for it?
Vehicle: Nissan Note E12 (Year 2013) (3 cylinder HR12DE Engine)

[make meh care]

not an easy thing to say buy a car with a 4 cylinder engine instead.
