13b & 13bT housings.?
 

im looking for a rear housing for my rebuild and i can get a near new housing but if from a 88 NA 13b. could this be used with the S4 13bt

Yes you can use it just switch the sleeves from the turbo to the N/A.

how do you swap the sleeves, arnt they pressed in?

If your doing a stock rebuild (stock turbo and water return line)make sure water galley on the side of the housing is open and not freeze plugged.I'm sure you knew that but better safe than sorry :bigthumb:
