New engine / re-registering

[Kiltie]

OK here's the scenario.

A four year old kit car all properly SVA'd and registered has it's engine replaced with one of a different capacity. The engine is imported from the US.

I'm wondering what the implications of re-registering the car would be given that the new engine has no provenance.

When I say re-registering, I mean getting a new V5 with the revised details.

I believe the engine manufacturer (Suzuki) will, for a fee, vouch for the age if given the engine number.

Any thoughts folks?

Cheers,

Eric

No problem - it's just like any other car once correctly registered, fill in the V5 with the new engine number and capacity they'll post you a new one back in a couple of weeks.

Done it a couple of times with car engine to bike engine conversions - no bother

Just fill in V5C with new number and capacity and Robert is your father's brother.

Simply send in the original V5 with the new engine number and pertinent details completed. The source of the engine should make no difference to the notification of change of engine number, cc etc.

Cheers,

Brilliant - thanks for the lightning quick replies folks.

Seems I was worrying about nothing.

Or if the new engine will increase your car tax band, you may want to forget about the change ?

[Kiltie]

I don't intend to ever use the car on the road - I use it for sprints and hillclimbs.

I'm thinking about the resale implications.

BTW, change is from 900 Honda to 1300 Suzuki.

Cheers,

Aha, here's another aspect for ya ...

Existing engine was manufactured in 1994.

New engine was manufactured in 2003.

Now, when the car was purchased, the seller indicated that due to the age of the engine, the car wouldn't be subject to emissions restrictions.

If true (and it could be nonsense for all I know) then perhaps ...

The above was something I was about to post but realised in time that it was bollox ...

Where vehicles are fitted with a different engine they are tested according to which is older i.e. engine or vehicle. For example, a 1995 car fitted with a 1991 engine (of whatever make), tests to 1991 standards for emission purposes. The onus is on the vehicle presenter to prove the engine age. The logbook or a letter from the vehicle manufacturer is acceptable.

So, piece of piss then.

Something to be careful of though.
If for example you are converting your super seven from a 2.0 pinto to a 900cc fireblade you may well be about to qualify for cheaper road tax. Because of this alarm bells can ring at the DVLA and they might want more details and proof etc. about the in going 900cc engine. which may (i repeat may) have emissions implications.

Apparently there has been a spate of old Ford Sierras having their engines changed for 900cc ones shortly before being broken up and used as a donor for a kit car. This in itself would not ba a problem but because the bike engine is so small the DVLA want to inspect the cars to make sure the engine has been fitted and it is not just a scam to get cheaper road tax. We all know that the Super seven guys are doing the "Paperwork engine change" for SVA engine age reasons, but the DVLA won't be thinking that.
Sorry for such a long winded post but you get the idea.
