Yep that is correct. It is the date of the engine that matters now, the date of the donor is irrelivant with regard to emissions. That was one of the main changes from SVA to IVA.
Building from one donor will allow you to apply for an age related plate which some people prefer. Q plate allows you to build it from whatever parts you want.

Hi Everyone.

I must be reading the IVA manual wrong. It seems to say pre-Aug 1986 was the CO<=4.5%, 1 Aug 1986 to 31 July 1992 CO<=3.5% and post 1 Aug 1992 CO<=0.2%/0.3%.

My Reg Certificate says my MX5 donor was first registered on 23/02/1995, which according to this post means I don't need a cat and CO<=4.5%, but from the IVA manual I need one and need to meet the 0.2/0.3%?!?

Am I being thick?

erm..... well..... yes

Read it again its the difference between 1986 and 1995

Erm... I see now. I should have had my coffee and read it again before posting.

According to the flow chart, they do a BET test first based on the tighter standards and if it fails then they go on to CAT1?!?

Anyway, thanks.

Don't worry, even the testers get confused! As mine did! They always seem to run the BET test even though the car doesn't qualify for it, I think it's so they can say "well you passed the BET test so the car now has to pass the BET test in future!" Or something, I don't know and I don't think they do either!

Thanks. That makes me feel slightly less stupid! 😎

Just re read my comment glad you never took offence to my tongue in cheek comment

Nah, I'm thick in the skin as well as the head!

Same as mot test emissions regs,they select from menu and do what machine tells them .

And don't forget the 1200.ppm HC reading,you can have low CO and high HC.

after you pass iva and reg your car the test std for emmissions required of your car is printed on your v5 so just take it with you to mot test

I used a pre 95 zetec that was a cat engine but run no cat.
