Those who did a 3sgte motor swap, Smog test Options

[apexi_gt4]

I'm from California and smog here is highly strict. But I just want to know with those who done a 3sgte turbo swap if yours passed smog within your state?

Why wouldn't someone be able to pass emissions with a 3sgte? its not some mystical motor or anything. Its not like all the turbo mr2s and alltracs have to bribe the emissions places. If you dont have any cats or an egr thats a different story. If you buy a JDM motor it wont have an egr assembly (I'd bet money you would pass without an egr anyways... its just he visual part of not having and egr valve that will get you... simple solution... make the motor "look" like it has one). But if you swap and are worried about emissions just keep the stock "downpipe" assembly (which has a secondary cat on it) and get a high flow or regular cat in the original stock location. The motor isn't some huge polluter... you will pass if you do it right.. guarenteed.

It's not a matter of passing tail-pipe emissions alone. A smog test also involves visual inspection, timing check, fuel cap, EGR inspection, etc. If you have a CEL, you automatically fail. If you pass EVERYTHING and have a bad fuel cap... you FAIL. We don't just "look" and say "it's all there"... by CA law, we check for functionality. Apply vaccum to the EGR and check for full functionality. That's the problem with emission testing in some states, CA being the common one. Alltracs and MR2 Turbos have no problems because they originally came with that engine. Anytime you swap the engine to something other than stock, you're supposed to have a BAR refferee look at the swap, check all of the emission parts, and either pass or fail. You cannot legally swap in an engine that came in an older car unless that engine is the same as your original stock motor... so that pretty much eliminates ST185 3SGTE swaps for 6th gens. There is the option of passing off the swap as a 94-95 MR2 3SGTE, but you better have the MR2 wiring harnesses because they do check the harnesses against the original diagrams. For the most part... good running engines with a good Catalytic converter will pass the sniffer... but that doesn't mean everything.
