first, the most heaviest thing in car move a few inch in front(compare to b engine), in a FF, it means alot.(bad handling, its not just the heavy weight from the motor, its also because of the position, some ppl said just use a CF hood to reduce the weight and u will be ok, its not going to work)
second, due to the small engine bay of civic, the engine is not sit right, the center of garvity is higher than b-block.
third, due to the engine is not belong to civic/integra chassis, the tranny is not align right to the wheel, the axles is not sit right, with that kind of torque, u will have lot of issue about the axles.
if your car is daily driven and u want to have some fun in road track, then stay away(edited) h22.(however, in 1/4, its hella fast though)
