yea, your looking at new mount and a different loom in that to accept the h22, it will go well, but your prob best off getting a type r engine as it should go in easier and its built for those engine bays
the H22 would be a major major operation. Don`t forget the K20 sits back to front compared to the D & H series VTEC engines. Also, compare the size of engine bays on the EP and Prelude/Accord cars. Bit of a difference eh!
Well now that you've brought to my attention i would have to change my engine mounts... Is there an engine that would increase my horsepower substantially that would not involve changing engine block and create extra work looking for more of a "clean swap"
