I want to replace the pistons block ect on my 1995 plymouth voyager with a newer block and pistons ect off of an 2007 caravan. I know that the oil pan moiunt is the same and the transmission mount is the same. I dont know if the mount for the heads are the same or flywheel. I dont know if the pistons are the same seems like they are not as thick. The question I would have is this even safe to do. Is their any important details I might be missing. Has anyone ever tried this before.

 

You are going to need a lot more than just the engine to go from OBD1 to OBD2.

 

I dont want to change the computer around just the engine block.
