IVA Unknown age Engine emissions testing...
Hi,
If I presented a car for IVA with an engine of unknown origin/age what emissions regs would it be tested to and would I need a cat?
Thanks
Shaun

If you can't prove it's pre' (sept?) 95' then it has to be tested to the full BETS test limits and will require a cat'
to pass.
From memory...
Idle (800-1200rp) CO< 0.5%, HC< 200ppm
Fast idle (2500-3000rpm) CO< 0.3%, Lambda 0.97-1.03

If you can't prove to the tester that the engine age is such that it would be tested to more lenient emissions limits then you would be tested
to the Cat-test limits.

Thanks for the info guys.
I have found a MX5 donor going cheap, the only thing is it is a dec 96 build so I will have to use a cat.
Thanks

what do you need to prove the age? I bought my engine from the scrapper and its apparently a 1994 engine, but I have no proof. Its a rover V8 by the
way. Is there anywhere I can get a date from the engine numbers maybe?

For ford engines I know the burton catalogue is accepted as there is a grid in there with the engine numbers/build dates. Unless you have a V5 with a
matching engine number to your engine it sounds like you may be tested to the above criteria.
It may be worth phoning a testing station to see what the will accept as id for your engine.
I see from your other posts that you are using sierra donor parts. If the above fails, You may be as well getting a sierra donor, using the engine out
of that and the v5 to get you through IVA and then transplanting the V8 in when you are road legal.

Just my experience.... I transplanted a Zetec ST170 engine into my donor and the Zetec was a 2003. This was all listed on the V5. The donor was 1989
but the test was done on the engine date not the date of the car it came from.. The tester looked at the engine serial #
