My bro recently crashed his integra GSR and the cost to fisxi it is about $2,000. He wants to buy a 92-95 civic hatch or a 95-98 civic hatch and put his engine and suspension in that car. All is possible but here's the thing, my dad told him it's illegal to put an engine with a higher liter ( 1.6 D16>> 1.8 B18...). My dad aslo would'nt want him to cary through with this swap because he does'nt approve of his racing, he legally races though (my dad AND bro).

So the question is... in Cali, is it illegal to put an engine with a higher number of liters? Please don't answer until you are 100% sure, please. I need your help guys.
