Well today while taking the t case and transmission off. I noticed there was a cut line it was rubber into hardline that then ran to the back with the brake lines. What does this line do looks like it hooks up to a black box in the back wondering what this does

 

Is it next to the frame rail by the driver side rear tire? If so it's probably your evap canister, used for emissions.

 

its in the rear of the evos? interested. its in the engine compartment on a dsm 4g63. or do cars have one in the front and rear?

 

sorry i never replied to this evap huh. I was wondering if i could remove it but i was thinking it might be a vacuum box or something

 

mine completely broke when i crashed my evo

 

Charcoal canister - Evo only one in the rear - DSM only one in front. The idea is to catch gasoline vapors that would otherwise vent to the atmosphere and purge and burn them in the engine.

 

yes, charcoal canister. my old wrx also had one at the rear underneath the rear bumper.

 

Removing charcoal canister will throw a cel, which then disabled using ecuflash. Hope your state doesn't do visual inspection...

 

Does anyone know what this box do?

 

Bump

Get rid of it. -10lbs. I used a couple pieces of rag zip tied over the ends of the two hoses left hanging down. Also get a blockoff plate and remove your EGR. STM has a nice plate...http://www.streettunedmotorsports.co...te_dsm_evo.htm

 

Charcoal canister you can still pass the emission

 

Yup, just vents into your intake manifold. Drop that shiz!
