The way you can get past smog is
- Do something illegal (fake smog)
- Find a shop that does not do a visual inspection and pass it on sniffer only (after some modifications)
- Live in a rural area where a dyno test is not required AND find a shop that does not do a very good inspection
For example, I know of a shop around me that does not look at anything. They hook you up and a quick smog test. This is a fly by night type of smog station and will probably be out of business soon.
In the meantime, I take all of my cars there
The other option, that most people use, is to drive with permits as long as possible. I have personally gone up to 8 months on temporary passes. When that option runs out, you sell it to a buddy and ride permits that way. You can often spot the 1JZ cars in cali by the red temporary pass at meets. Most people do not keep the car more then 2 years, so it doesn't become an issue for too long.
For me, I just smog the car before the swap. That way you have 2 years to play with.
