Doing a turbo swap on my '91 RX7. Some of the hoses on the donor eengine were cut so I have no idea where this is supposed to connect or what it's purpose is. It's a line of somesort that bolts to the lower intake and has a banjo bolt.

If you know please enlighten me.

Thanks a lot, Ben

 

Oh, and btw, I looked through my Haynes manual and the FSM on Foxed.ca But couldn't find anything, so yeah.

 

brake booster line......i think.

 

Yes, it's the brake booster connection on a J-spec LIM. The hardline for it on the firewall will still be in a decent position to attach, but you should rotate it around the banjo bolt to get it to line up better.
