    For the plastic coolant pipe when you re-route the top hose back to the block, use the E36 equivalent. It has a bend that pretty much lines up with the connection on the block.

    plastic coolant pipe under intake manifolds loves to fail and is cheap. and also take care of the mess under the intake there are like 8 vacuum/coolant hoses that can be simplified to be 4 hoses. clean your idle control valve also. maybe fuel pressure regulator too while your there. have fun i just did all that

    buy two (or three in case you f up) dowels for the engine block. makes for easier surface prep. they are part # 11121726241

BMW updated the design a couple of years into the E36. The case is a direct swap, but you do need to get the updated metal gasket that goes between the case and block. Since you plan to have the engine apart anyway, this is a no-brainer.

    Also, replace all of the timing chain guides and sprockets.
    I'd add to this list the oil pump. I know these things typically are bullet proof, but on my last build my pump was bad which lead to a tear down. I'd change it for piece of mind.
