COS80
SILVER Star
The best part of this is, by the EPA's own data, every single V8 engine I considered swapping in polluted less than the 1FZ it would have replaced. That's why I spent triple my budget on a supercharged 80 with an EPA sticker - so I can keep polluting until I'm 80.This conversation clearly illustrates my problem with US emissions laws. I've got absolutely no problem with helpful environmental legislation, but this is only good for keeping older rigs off the road. In the case of motor swaps, what would be logical is to require emissions testing at the end and if you can prove it's as clean or cleaner than original and gets equal or better mileage, job done. Especially in a case like this where we're literally doubling OEM mpgs.
This though, if they're following the California rules like I think I understand it, they're going to want to see your particulate filter and your exhaust fluid tank. I can imagine them wanting the GM airbox in place as well, even if you get them to buy off on all the changed intake routing to be equivalent. If you can cram all that crap in there and get them to buy off on it, maybe you could delete it all after the fact, but I don't know if you've got the space under the hood without some massive cowl-induction style bubble or something. Even then, the way they have it rigged, the smog referee has no real incentive to help you out. I don't know... maybe break out the lip gloss and the knee pads.
Their business is driving old cars into the crusher and us into electric busses.
