Hi all, mite be a stupid question and already been answered but here goes!
I am hoping to retain the age related plate from my donor which is a K reg, this is 1992 am i right in thinking that i could get away with a no cat
test at mot after sva? or does it not work like this?
Mike
Mine was registered on an H plate.
My local MOT station said it would be tested as an H plate as there is nothing on the system to say it should be tested otherwise
Right, this is AFAIK, and therefore, probably wrong 
I think the emissions level you need to pass depend on the age of your engine at SVA.
If you pass the SVA with an old engine, then replace it with a new engine, I "think" you only need to pass the MOT emissions level of the
old "SVA" engine.
No doubt someone will come along and set me right in a mo'
At SVA it's tested by age of engine so you'll need a cat. After that, I think the MOT tester will test by the registration plate year (or
visible smoke if it's a 'Q' plate). Not sure how this works with personal plates though.
Having said that my V5 has emissions limits in the notes section. This info may be available on the MOT computer as well.

Yep I think you are correct, cat for SVA then on cars age related plate. I think it is smoke only for cars with a pre "S" prefix...Check out
totalkitcar web page they used to have info on there.

I was under the impression cars before 95 didnt need a CAT test but some cars were fitted with cats from 1991 etc??
Emissions decided by SVA, when they decide what age engine you have they test the emissions to that value and then that value gets put on your MAC and
V5, this is then stored on DVLA computer and your car will need to pass this value for evermore.
My V5 donor is for a very early Pinto, CO 4.5 the newer engine will be in the CO 3.5 level but after that throw it away and put any engine you like
in.
The engine age and emmissions issue is a very serious thing and i am still surprised people get so very far into the build before looking into the SVA
and MOT issues
Doesn't need a CAT for SVA cos it's pre '95, will be tested as a K reg for MoT which will be 3.5% Co & 1200ppm HC's
With regard to emissions at MOT, the MOT tester will take the age of the vehicle from the registration plate and also assume that this is the date on
which it was first used.
A - If your car has an AGE-RELATED plate he’ll assume that the engine is the same age as the plate and do the test accordingly. However, if your
age-related plate refers to pre-Aug 1998 (‘S’ Prefix) you will continue to get the visible smoke test for the life of the vehicle REGARDLESS of the
age of the engine. Remember though that this does NOT include PERSONALISED plates as in this case the vehicle will continue to be tested according to
its age and NOT the vehicle registration number.
B - If your vehicle has a CURRENT/NEW plate or one that is after 1st August 1998, you will get a ‘basic’ emissions test, which is a basic check
conducted to set limits carried out BEFORE the ‘CAT’ test. If you pass, GREAT. If you fail though you’ll be subject to a full ‘by-the-book’ CAT test,
plus remember that if you fail this you’ll also fail the MOT. Of course there are plenty of CURRENT/NEW registered kits running around with
reconditioned engines so in this instance you will have to prove the age of the engine to the MOT tester. Ideally you should have a copy of your SVA
MAC ‘pass’ certificate, which will be sufficient. Otherwise you will have to get a letter from the engines manufacturer stating clearly what year the
engine was made.
C - Cars with a ‘Q’ plate are regarded as being of uncertain age so therefore will continue to be subject to the visible smoke test.

Phil,
any idea how that would work with an age related private plate?
Mine has an H prefix private plate on.
