Ok i have a 5sfte and i was told that if i were to just put on the stock cats and mufflers on to the turbo downpipe, which already has a cat on it, that i should pass smog. Assuming visual part is over looked.
these are the reason behind the thinking
1. just as long as the turbo isnt spooled up to high boost levels the 5sfte should run much like a 5sfe. From what ive heard when they smog the car they arent gunning it and thus my turbo shouldnt be putting to much pressure into the engine. If n e thing i can just discconect the wastegate from the accuator and prop the wastegate open thus not creating boost.
2. with the stock cats on it it should burn up what ever needs to be burnt up much like when the engine is stock.
3. with the safcII im able to keep the a/f ratio during non boost periods at about 13 to 15 to one. This compaired to the richer a/f of the stock fuel map. thus the larger injectors and fuel pump shouldnt matter.
4. If i take it to an asian/gehto place they should just over look the intercooler pipes and stuff. Everything else under the hood like the msd ignition is carb certified and thus smog legal.
5. worse comes to worse all i needed is another cat to be put somewhere in the piping.
what do you smog/emission experts think?????
