engine conversions & TAX



  ValverInBits
I know when you do an engine conversion it's perfectly legal and normal to ring the insurance company and inform them and they change the insurance....

.....but what about tax?

Especially with these new 2001< rules

What happens if I put a 1800cc turbo from 2002 in a 1994 clio 1.8 16v ?

Is the standard car's tax rate affected ??
How do you inform the relevant people about changing the V5 ??
Would you need to inform them as it's an 1.8 to a 1.8 conversion ?

You have to inform them of ANY major change.

Infact there is a points system for any radically altered vehicle, probably not a problem with the clio, but you may need an SVA for some conversions.
Each major component is worth so many points and the total must be made from 8 manufacturer STANDARD parts for that model or origional parts for the car, ie body shell 5pts axles 2pts, engine 1pt, suspension 2pts, steering 2pts transmission 2pts. So you could keep the body, axle/s and steering and have 9pts and change everything else legally.
Once so many of these components have been exchanged for NON standard or uprated items eg putting a V8 in a capri and changing the box diff and suspension on the car technically has to be reregistered or at least go through an SVA with and you need an engineers report. Like I said might not really matter too much in the case of a piddly clio engine swap but they are hot on everything these days.

You will have to inform the dvla of the change although it wont affect the taxing as your putting and 1800cc lump into a car that was originally an 1800cc..

thanks very much mate, very informative

Where does that leave me with tax??
If I have enough "clio points" for it to be a clio, I pay the original tax bill?

edit: thanks ivan, answered the above

So long as you keep 9pts then the car is legal, you 'may' still need an engineers report of the work (you could get a certificate from a Renault garage for example if they'll do that sort of thing) if you the work yourself.

I know of a couple of Ka's that have had to have an engineers report because the engine has been exchanged for a fiesta turbo cvh. so that's 1.3 ohv > 1.6 ohc turbo. That also effected the tax (from £130 to £180)

As far as I know you tax the car as a '94 1800cc still. eg I could put a new skyline engine in a 1971 cortina and still get my free tax so long as I adhered to the dvla rules mentioned above.

The rules were brought out for kit cars but typically have filtered down to effect the car modifiers too.

With regard to an engineers report just go down to your local friendly garage slip em a couple of quid and just get them to write you a letter stating that the car now has a new engine with the new codes and with the letter send it to the dvla along with the v5 and within a few weeks you will have a new v5 logbook with the relevant changes...

When i swapped my engine I just went to my DVLA office (to tax the car too) and told them of a change in CC. I told them it was a new engine, but they just changed the CC and my old engine number is still there :? - can't really be fooked to change it

my car is taxed as a 2.0 under the old scheme, despite the engine being from a 172 which could possibly be taxed on emissions, so not sure if the emissions tag 'follows' the engine?

Nothing to worry about but if you get a chance just change it, if something happens to your car you have it on record that it was all done above board.

Good to get friendly with a Renault garage / specialist. If you have an engineers report from an official garage it looks good when you sell the car on.

I really can't see them kicking up any fuss if anything were to be 'inspected' - not like i've tried to hide it


thinking about it, my engine doesnt have a number plaque on it like the old F7P... do F4Rs normally? - I know the engine number from the donor car's reg though
