I have just aqquired a top mounted IC from a 2nd gen RX7 and was wondering what the other 2 pipes are for, not the airflow pipes, it seems like they are coolant pipes of some sort. Any insight as to what they are? Thanks

they aren't coolant pipes, hooking a coolant line up to them would be pretty bad....I'm sure where they go off the top of my head but tommorow I will look and if I can get my digital camera back from my brother I'll take pictures for you... see ya

They're vacuum lines, but I don't know what they are used for. I tried to start mine after I forgot to re-attach them, and the car died right away.

yeah they are vacuum lines prolly to make something turn or off under boost or no boost .... you don't want liquid cooler do you ?? hehe

I believe they are vacuum lines to control the blow off valve, not completly positive on that though

They're for the fast idle when you start the motor cold.
