it kinda is and it kinda aint,if that makes since...im actually running the same setup but with a built bottem end.things you will need for the swap to work though..such as the h22 crank gear,h22 water pump gear pressed on a f23 water pump,h23 headgasket,waterneck modifaction(it has to be lenghtened),complete h22 head with 2 of the oil drain ports pluged,h22 timing belt.the list goes on but if you wanted to try,more power to you..
