I have a fc that idles rough, and seems weak, and when i checked compression, only have like 60 psi on rear rotor, front was like 95 psi. I guess it is cheaper to do a engine swap than a rebuild?

 

Sometimes it depends, if you can do your own rebiuld then it can be some what cheaper i think a master rebiuld kit from say atkins is like 900 for a NA and 1200 For a Turbo model.

You can prolly find a motor for pretty cheap if its a short block, although i don't know if its assembled or not so thats another factor but there are plenty of resources to help figure out what you want to do

 

Has anyone ever went through apex in oklahoma, and tried buying the rotors alone, or is that a option
