What the biggest engine i could swap into my 4th gen accord? Is a h22 the best i can do? What's the best i can do with no modifications?

Also, is there a chart somewhere that would tell me all the engines i could swap into my accord?

The first question I have to ask you is, are you a complete idiot?? "What's the biggest engine I can swap into my Accord?" What the hell man... Yes, it does seem that most people seem to go with the H22 swap. But why you want the biggest engine is beyond me. The question should be "What's the smallest engine with the most ammount of power I can put into my Accord?" The H22 is a beast as far as DOHC goes. But fortunatly for us Accord guys the power to weight ratio is still good. Personally, I think you should sell your car, cause you're too stupid to own one.

the biggest engine you could fit would be the h23 non-vtec

wow jdm accord, some people arent a "genius" like you. anyway to answer the post. You will have to do slight modifications to any motor you put in the car, but the H series is by far the easiest all u neesd it to grind down alittle metal to get an engine mount in. You could go crazy and put the acura TL type S motor in but that would be hard as hell and very unique and that would be the biggest motor that would physically fit in the car.
