    emissions and other questions from new owner 02' WRX

    will I be able to pass emissions in Wisconsin with my 3' turboback exhaust? Also what is the complete list for stage 2? I've heard exhaust, intake, accessport, and up pipe. What are the best spark plugs, and oil for these cars I'm trying to do a complete tune-up.

    Potentially. The process is

    Wisconsin Vehicle Inspection Program

    and if you don't have a CEL visible plus if all sensors report "ready" it seems you will be able to pass. However if the tampering is evident, you have a CEL, or a sensor does not report ready then I would expect to fail.

    Generally no intake.

    What are the best spark plugs, and oil for these cars I'm trying to do a complete tune-up.
    Check the manual for the spark plug specifications, they give a model for NGK for example; also check for oil specs and use something that meets those specs and has generated good used oil analysis data. See the oil change thread here or Bob is the Oil Guy (the entire web site) for more info. I use any synthetic 5W-40 or 0W-40 in mine (Shell, Mobil1) but that's not really informative for you; data would be.

    Sorry didn't see your post.

    Plugs as spec'ed by the book unless you prefer the equivalent iridiums. I only used them because they're cheaper. I'd stay NGK as per book.

    Oil by the book for spec., and personal preference or price for brand. I use Rotella T6 because it's robust and affordable. I'd just as well use M1 on sale.

    Swap trunks and torsion bars with someone, it's easiest. Sonic Yellow is a great choice but a quality colour swap could exceed the value of the entire car.
