I'm getting rid of my evo here in a few months and working on returning it to stock. I have the Grimmspeed EBC and i have been searching all over how to re install the stock ebc. Is there a write up on this ? ive tried searching but no luck. Thanks!

 

Also interested in this, i don't even know where my EBC is...

 

Going through this tomorrow, looks straight forward.

1. Unplug black and brown connectors to 3port.
2. Disconnect all vacuum hoses that come from the 3port (one goes to intake, one goes to waste gate actuator, other is just above turbo)
3. Remove 3port from bracket using appropriate socket, reinstall the stock BCS into the bracket after removing the 3port.

If you kept it together (which I did fortunately) all the hose routing is pretty straight forward to reconnect.

4. Next reinstall bracket, reconnect hoses, reconnect the brown and black connectors and you're done! (reflash to appropriate map)
