What year is your es? If it's 86 or later, the swap is plug and play. If your es engine is tired, swap the 5er engine in. It's the same M20B25 that's in the late model 3s. No great advantage in putting the 885 head on the e engine without other mods. (Others will disagree, but it's true). The intact engine swap will be a lot less work overall.
You'll need a Z3 rear for the five lugs on the back, and M3 hubs and parts for the front. Lotta work for little advantage if you ask me. There are tons of 4 x 100 wheels of all widths and diameters.
