I know the GReddy kit is smog legal. But if you add.....what? Then it's not?
What parts and why?
New to the turbo stuff.
GSRgrrl's turboed GS-R got me thinking......

 

I'm going to throw out a guess and say its the 12:1 FMU. Probably makes it run too rich too pass emissions when its boosting.

 

the external wastegate and the BOV venting to atmosphere

External wastegate venting to atmosphere is key... also the fact that a large turbocharger cools down the exhaust enough that it makes the catalytic converter significantly less efficient, especially on startup. Even with perfect fuel tuning it won't burn as clean as a non-turbo car, unless you take some serious measures with startup fuel and ignition to heat up the catalyst.

 

how does Subura pass emmisions?

 

you will fail "the visual inspection"

 

If you add things, most of the time those boners won't notice because they really don't know much about cars anyway.

Either they'll pass you with the carb sticker, or they'll fail or not inspect you because they don't know what is what. A place here wouldn't inspect me for having a cone air filter before I had the turbo on.

As far as I know, air filters do not have to be carb approved. Depends all on where you go though.

 

The extra fuel pump and fmu will make you fail visual like that.

 

subaru doesn't have an external wastegate

 

Here in wisconsin it is Illegeal to have an open air filter element. Making pretty much all aftermarket filter systems Illigeal.

 

Subaru has THREE catalytic converters, one of which goes BEFORE the turbo, for the sole purpose of reaching operating temp soon enough to pass US emissions on startup.

 

Subaru allso vents it's bov back into the intake. steering away from atmospheric venting.
