MBC Install instructions or guide. - ClubWRX Forum - Subaru Impreza WRX and STi Community and Forums

AsILayDying · 01-04-2010, 04:27 PM

I have looked through a couple of the posts I have found through search but nothing to detailed or with photos of how to install a MBC in a WRX/STi. If someone could just point in the right direction it would be appreciated, I know this should be a simple install but I am still relatively new to Turbo vehicles, and all the terms or names of lines of hoses and such are a little tough to figure out just by words. A good photo does wonders. Again thanks for the help.

The reason for MBC install is because I am overboosting with COBB AP Stage II and they recommend a MBC and turn down boost a little until I can afford a ProTune map. Im tuned for 16.7 and Im peaking 19.5psi. Thanks again for any help.

Good link.

As I lay dying...

Remove the T to the BCS... remove the restrictor pill inside the vacuum hose coming from the compressor, but leave the line... and put the MBC in where the T was originally at.

It's cake. You can re-route vac lines, do some mounting, etc... but that's the principle.

Also you better have a tune to go with it especially with an 04-05 wrx.
