As Celica_RA40 said they are all the same block. Only diff is the oil pick up point to suit what body car (cross member position) it is in. so if you put a engine out of a ra 23 in to a hilux or visa versa you would use the sump from the car is going into and the oil pick up pipe only. Basically a dry sum has a pump to suck the oil out of the sump to a tank and a second pump pumps it through filters and back into the engine, this eliminates oil surge if the tank is big enough.
