hey guys! The weekend has come and its time to continue work on my fd RX7. I've basically looked up and found every single vacuum line and electrical connector on the car except 3. I was just wondering if anyone knew what these 2 tubes/lines were hooked up to? Any help would be absolutly appreciated.

 

to your turbo intake duct, which isn't installed.

 

thank you! Are they just vacuum lines that I can Tee togethor and run into the oem intake duct or can they be capped off?

 

they are atmospheric lines, one is for crankcase ventilation and IIRC the other is for fresh air for the oil metering system. so no, you wouldn't want to cap them. you can run them to a post filtered spot in the intake prior to the turbos.

or you could put the proper turbo intake duct back on and put them where they are supposed to go.



i probably have one if you want to go that route.
