Im about to get a ef ex(?) with the stock motor/tranny. I have a spare d16y8 with a bent valve and i want to put it in the ef. What parts can i use off of that stock motor(d15 i believe) and also the guy who is selling me the car also has other dseries parts z6 head, d15 block(bored) and some d seris integra pistons and rods, so what all can i use and do i need for this swap to work??
