can u put e55 brakes on a 320? If so what will i need calipers and rotors. I have 20's on the car so wheels are not a problem. thanks for any help

Hmm new rotors, backing plate, knucle, calipers, brake lines, and many many other things. If you want E55 parts go buy an E55 it will be easier.

Yes, you'll need calipers and rotors. I priced it out a year and half ago but never did the swap. Full List is $4347.62 for parts + tax, I was able to get it down to $3098.00 + tax for parts. Send me a PM with your email and I can scan and email prices/parts next on Tuesday when I get back to work if you are interested.

the front spindles must be replaced as well...different dia for the caliper bolts
it can be done for less than 3k

You'll also need clearance in your rims for bigger calipers. Not all 20" rims have the clearance for BBK.
