Anyone know where i can go to pass smog for an FD? i am probably buying one soon but it doesnt pass with all the mods...

FD Oil
 

whats the best type of oil to use on an FD?

Single vs Twin turbo
 

whats the advantage or disadvantage of single over the twins?

Assuming Marin is in CA, it probably won't pass unless you can find a tester that takes bribes. If you want to learn more about any RX7, read the FAQs in the appropriate gen section and use the link in my sig line to download the online FSM.

FDs can pass smog with a working secondary air injection system and a good catalytic converter.

Single turbos can be built to pass smog, but most aren't set up that way.

If I were in Cali I'd absolutely consider if a car passes smog when I make an offer. Passing smog is a major hassle with a car that can't do it.

Have a look at the 3rd gen FAQ. It's linked at the top of this forum.
