I have done a 2.5 to 3.0 swap before. I have actually used the existing accessories, and it works great, no codes. However, it is best to go ahead and get the bigger maf, intake, airbox, and computer. Everything else is the same. The manual gearbox is the same from a Z3 2.3i to a 530i, as long as it is a 6 cylinder, it will work. You can even put a 6 speed transmission from a e46 330i ZHP in as long as you can get the driveshaft to work.
