Most of the parts will not be directly compatible. The Type R shares more parts with the Civic Hatch than the sedan or coupe SI. The grill, some of the interior, stuff like that will be compatible. The wheels, bumpers and lips, exhaust, are not compatible without modifications.Anyone know if the Type R parts are going to be compatable with the Si's? Would be nice to have the front lip spoiler from the Type R
