Washington Emissions Versus Aircare

I'm planning to import a swapped 1993 Supra TT (originally NA) with a USDM ECU. The seller says it passes Washington state Emissions no problem (has stock cats); are the pass standards the same as Aircare in BC?

I know they test OBD, but what about the actual emissions levels?

Sorry if this has been asked, I tried to search for it, but I couldn't find the answer.

Thanks in advance.

1993? Good luck. 1993 cars are required to go through the IM240 test. If the car is stock (which I will assume that it is) and retains a stock catalytic converter and ECU, you should pass unless something is terribly wrong. I don't know if you've already purchased the car but if not, get that car through a PPI before committing.

I can't speak for the emissions standards between BC and WA nor do I know the standards for that particular car. You'll find out the standards for that vehicle AFTER the test.

From the Aircare website:

1992 and newer vehicles (except diesels) are tested using the most advanced dynamometer test currently in use anywhere. The test measures emission levels for HC, CO, and NOx while the vehicle is driven over a pre-defined series of accelerations, decelerations, and cruise conditions. The test may last up to 240 seconds depending on how "clean" the vehicle is in the early part of the test.

Read more about the IM240 test procedure.

Watch a video describing the IM240 test procedure.
