I live in the state of Tennessee and I have to do a emissions test ever year.
Is it even remotely possible to get a turbo / sc car through emissions?

Have anyone passed emissions in the US with FI?

You might be lucky http://www.state.tn.us/environment/apc/vehicle/obd.php

So long as you don't have any CEL's you might pass.

 

If the AFR at idle is near stoich, why wouldn't it (as long as you don't have CEL's)? A lot of FI'd folks remove their cat to get better flow, but you certainly don't have to. That would certainly lead to a failed emissions test!

 

Like others said, I don't see why it wouldn't pass the actual emissions test. It would fail the visual inspection, unless you were able to hide everything with the stock engine covers, which can be done with the geddy kit. Just hope they don't take them off.

 

Even if you don't put the engine cover off, if you put the stock airbox back on, it just looks like you may have an aftermarket intake. So GReddy people should be able to pass.

 

Not very many states do a visual. As far as I am aware, Tennessee only checks for codes. I had a 420a eclipse with a built motor, big turbo, exhaust, high flow cat, emanage, big injectors, etc, and it passed emissions just fine in Georgia. It is possible.

 

I'm not sure about the emissions laws there but here in Texas we don't have a visual inspection. Even if they see you have mods, they don't care. All that matters here is that everything checks out when they plug into the OBD-II port. Even if you do have the sniffer test, you haven't touched the porting of the engine so any effects on emssions should be minimal at best within the test range and it should still pass.

 

Guess I'll don't have to loose sleep over this issue anymore. Not that I have a turbo / sc yet, but now it becomes hard to resist Hymees Twin Screw

Thanks guys.

 

ahem... just wanted to point out the humor in this post...

 

I wonder why nobody markets a twin screw SC coupled with twin blondes

"Screw the twins and hear them whine!"

 

Ajax's sisters are the FHM magazine triplets! Why don't you go ask him. 2 for show and 1 to go!

 

 

So hows the weather there in Texas now? I'm willing to take some time off work to do some travelling. Giggity giggity giggity!

 

Derr!

Maybe I shouldnt have told you that :b

 

LOL!

Back on topic... depending on how strict the tailpipe check is... and S/C is your best bet. A turbo isn't impossible... just more difficult if they are going to get as detailed as checking tailpipe emissions on a cold engine. The turbo will suck heat out of the exhaust making your cat take longer to get to operating temp... thus my S/C comment.
