i have a crx hf and i love it but the motor sucks so i was originally going to get an h22a for the power and because they are cheaper then b series engines. but ive heard a lot of work goes into puting one in a crx so i desided not to go with the h22. im thinking of getting a b18b but i dont know how easy they are to fit in a crx. i know they are heavier then the piece of **** that is in there now but is it a lot heavier to where i need new springs and shocks? is there any serious things i should before i purchase one and put it in?
