Engine swap BA4: B20A3 to B20A9


does anyone know if it's possible just to swap the engine head, manifolds, ecu and wiring- so almost everything but the engine block and the gearbox? It get the fact that I'll also need to change the fuel pump and all since I'm trying to go from a carburated engine to an fuel injection one. But I wonder if the engine blocks are the same and if I'll get the same HP out of it. I've found somewhere that the compression rates are different for these two engines, so that's why I'm worried.
Has anyone ever done it?
