i need a new egr for my 86 305 tpi iroc. lookin it up on Autozone there are 2 diff part #'s one for Cali. emissions and one for fed. emissions

http://www.autozone.com/addVehicleId...leSelected.htm

i do not have access to the car where i could take a pic of the old one.

it was built at Van Nuys.

should i check the rpo's or vin or something?

thanx!

This should probably be in Tech/General Engine instead of Exhaust.

 

As far as I know, the TPI cars were all built the exact same way, meaning there is no difference between CA emissions or Federal emissions. I dont know why Autozone lists two different part numbers, but I would look at both of them before I bought one.

 

ok thanx guys...

 

RPO codes are NB2 for California Emissions, and NA5 for Federal Emissions. But your profile says you live in Florida...

Being built in Van Nuys wouldn't have had anything to do with emissions. The determining factor was the state the car was built for.

TPIparts.net shows 3 different EGR valves used on TPI engines from '85-'92. None, however, are based on CA or Fed emissions, but simply on engine/year. And the only one shown for your car matches the Fed emission valve shown by AutoZone in your link.

Edit: well, the tpi site doesn't SAY yours is the same one as the Fed. It says yours is the same one as used on '87-'89 350 TPIs. And checking AutoZone for those 350s, they show only one valve, and it's the same one as the Fed they showed for your car. Clear as mud?

 

ok thanx.

sorry forgot to mention, i am a resident of maryland, where my car has failed emissions twice and my 2 year waiver is up in october 09. i go to college in fl.

 

I believe that the emissions is based off the year of the car not the engine.
so if you Camaro is a 1982, then you need to meet the standards for 1982, not for the 2016 engine that you put in the car.
