smog specs 89 mustang lx
 

Hey fellas,
Im new here and in a jam. I just bought a 89 5.0 lx form florida and shipped it out here to hollywood ca. I didnt realize they took all smog legal stuff out. SO question one is can anyone tell me where i can get the smog schematics or smog specs for the car. Number two can u give me a list of what i need to put it back to smog legal standards by using high performance kits (dont want to loose the power i have now) Im told that shorty headers with o2 cut out is fine and high flow cats r legal too can u guys make it easy for me? help!!

OK you need O2 sensors regardless, if you start adding Emissions stuff you will loose the HP, if your worried about inspections, find a race shop and get it inspeced.. no one likes the smog stuff.. I would never reinstall it.

you're screwed. CA has the worst smog laws, as you should know already...

you need stock H pipe, (4 cats) and all the stock smog stuff. Buy a Haynes or Chiltons manual and go junkyard diving. Or, you could get a po box in san bernidino co and register the car out there, no smog....

Your car originally came with the following emission control components:
Name: / Service Number:
Thermactor air bypass valve assy. / E1TZ 9B289-C

To be smog legal in California, you must have each of these installed, or a replacement that has been granted an Executive Order number by the California Air Resource Board.

wow thats amazing
 

thank u very much but is there anyway u cant tell me what i can replace any of those parts with high performance/smog legal parts? and also what u would do to a 5.0 to make it fast while still having all the smogs on it?if u had lets say 5000.00 to spend or less?
