[DML] Re: Emissions

Hi John...

You are absolutely correct.  I'm sorry...my previous statement was a
bit misleading, please allow me to re-state.  I had called the state
DOL & emissions department with regards to an engine swap.  They said
that by federal law I am not allowed to modify the car from its
original setup.  I asked "then how do people get away with all these
custom hot rods, engine swaps, etc.?"  He said that for cars that had
emissions equipment as stock, you are not supposed to modify them
whereas some of the older hot rods (i.e. 57 Chevy) were built before
the requirements were in place and are grandfathered in.  As for newer
cars he said that they don't check the cars to ensure that they have
the original equipment in them and he listed off various reasons as to
why they don't check for OEM equipment...which is probably a good
thing because even if I had a stock DeLorean, the emissions guy would
have red flagged me because he thinks those cars are supposed to have
2.9 liter 4 cylinder engines.  I suppose I could have complied by
unplugging two spark plugs.  ;p

Because the Washington Emissions folks don't check for OEM equipment,
the DOL person told me that I should be fine as long as I pass the
emissions test, and as long as I didn't volunteer the fact that I had
changed the engine.  Doing so could result in a serious fine up to
~$10k...or they could simply just fail me on emissions.

In Washington State, this is the last year for emissions tests on cars
built in 1981 and older.  So I won't need to worry about my other
DeLorean which has a Cobra engine?it may pass emissions as I have CATs
for it, but since it's a V8 instead of a V6 there might be an issue. 
Who knows?honestly I am not anywhere near the title of an emissions
expert, I am just regurgitating what I was told last week by those
claiming to hold such titles.

Information on Washington emissions can be found at
You can even check my results via vin#.  I have an 81 Grey Auto, #
6406.  Note to everyone; please don't post my VIN or personal
information on the forum.

Also WA State emissions law is RCW 70.120

As for your CAT...I don't know if you have seen a BAE Turbo setup or
not, but it doesn't leave any room for the stock CAT.  The angel of
the stock CAT piping also doesn't work on the BAE setup.  Your CAT
looks like it's a direct replacement for the stock CAT, so I doubt it
would work in this case.  However, if you can have custom CATs made,
it would be possible to slip a CAT into the BAE setup, but it would
have to be thin and small.  If my car didn't pass emissions, I was
looking at putting in a thin high flow CAT from an NSX.  The only
problem was the NSX CAT I was looking at was ~$700!  Doh!

Sorry for the lengthy e-mail?I am a serious windbag!
