I have been doing a B16 swap in my EF. Every problem that can be encountered has been. Now the only thing that stopping me from sporting my EF again is the bolt (what is this thing actually called??) that the castle nut goes on behind the front brake rotor. It's stripped. Anyone have any ghetto ideas....possible doing the threads....what size retapping and nut size??? I was thinking about getting a new one of those pieces from the dealer or the whole assembly from a junk yard. Any idea how much this piece costs from the dealer and how long does it take to get it??? How much to press out and press back in? How much is the assembly from the junk yard? Any help would be much appreciated. I also put my EF9 conversion on...went on without a hitch. I need new fenders though. I got an 89 hatch. Is it better to get 88-89 fenders or 90-91 fenders?
