Look what I found on PT:
I’m an emissions inspector for the MOE (ministry of the environment) of Ontario. When we input data into the computer, then engine selection is by displacement, not type. It doesn’t matter if you change the engine because the engine you replaced the original with is of the same displacement, so it gets tested against the regular (factory) emissions specifications for the year of the body chassis. There is a test method for testing modified cars, called “Hot Rod” testing, however, our cars don’t qualify. A Hot Rod is any car whose engine block displacement is a size not offered by the original manufacture for that vehicle during that model year. So since a KL-DE and KL-ZE are the same displacement size 2.5L V6 it’s not a hot rod, that’s why it fails. Hot Rod status sets the emissions standard levels to 1980 specifications.
In Ontario, we no longer do the visual tampering inspection, we just check that the car has a CAT and a working Gas Cap, everything else is ignored (EGR, air pump, ect), although some inspectors still do the tampering inspection even though we were told not to as of 2002. We don’t even care if your check engine light is on.
You only get 2 retest at $17.50, if you fail a 3rd time, price goes back to $35 for each subsequent test after that.
I'm not sure what the laws are in your area as far as emissions testing goes, but here in Ontario, Canada, if your car has an engine displacement size that was not offered by the manufacture for that year of the vehicles body chassis, then it qualifies as a Hot Rod and emissions standards are to 1980 specs.
However you will have to provide proof that the engine was changed by providing a work order or receipt of the work done.
So yes, if you have an MX-3 and put in a KL-ZE, and have a receipt or work order of the work completed, it will qualify for Hot Rod status, but only for folks living in Ontario, Canada
I live in Ontario and have a 2.5L in my garage, got KL31 cams on my bench and got my MS8 delivered this morning. Been struggling with what to do for emmissions....Not any more !!!
