Okay in this constant search I am at the looking over the cliff part of this hole thing and once you jump I think you know where that is going. For the Gs 300, If/ when you upgrade your engine and add a turbo kit to it can you pass an emission test?

in CT you should be ok as long as its tuned right. In states like california that are much more strict, it's tougher to get around.

Actually the kit that I was looking at the SRT racing guys told me straight up, your not going to be able to pass emissions with it, so it's kinda like hmm okay and all the states up here have emission's standards so then what you can't always find that guy to bribe I think I might have to move to Idaho/ FL they don't have any

I was wondering the same thing about VA. They are strict here as well. But as long you don't have any check engine lights, i think your ok. They no longer do the tail pipe emissions test, they hook it up to your OBD2 sensor.

I understand that however it is still reading the same info just from a more reliable source the CPU of the car and none of it has the ability to escape into the atmophere so it is more precise so to speak...So is registration "trickery" the only solution?

jcat_350

That's not true as far as I am aware. Does CT have modification rules? If it's just safety and emissions you can easily tune it to be able to pass emissions.

I was talking to the sales rep. and parts people yesterday, I'm not quoting hear say, they are saying that the kit requires you to bypass the cat. and since it is being bypassed the vehicle won't pass the inspection.

Hi i am a noobie here but jus to see if i can help on this topic. I am a Smog technician in California and it is very strict here. Mostly all turbos and S/C are illegal but very few like Greddy i believe has the CARB# on there that makes the turbo legal but that only passes visual inspection. Once it runs the tail pipe test and your motor is heavily modded, you will fail..

Very true. Even if the car is tuned well after the turbo, if the kit is not legal and CARB approved, the smog technician will fail you on the visual. That is, unless you do an "under-the-table" smog.

jcat_350

with an NA-T setup you do not HAVE to bypass the cat. If you do, you should use 2, dual channel o2 simulators for the downstream o2's, leaving your upstreams in place.


I guarantee, that with this setup, your ECU will not throw a light or code, and when tuned properly you WILL pass a sniffer.

LamboGS3

that might be true, it wont throw a like and WILL PASS the sniffer but it still wouldnt pass the Visual Test. Out cars arnt like celicas and RSX where the turbo sits in the back and out of view. unless you do it under the table.

LamboGS3

pretty much the bottom line is you are NOT going to pass smog with Turbo.. no matter if its tune right or what not. the only way is to get it smogged before adding turbo, take out the turbo and get it smogged them put it back on, or do it "under the table"

^^^^Best answer regarding this issue.^^^^ And if you install at the ecu, you can install inside the plastic ecu case and you will pass visual.
