I'm looking into doing an engine conversion but what needs to be done afterwards to make it legal?

All I know is you have to contact the DVLA to get the V5 changed.. Is this free? and how long does it take to do?

Also do you need official checks by a mechanic, kinda like a MOT or anything?

Tell your insureance

your insurance sometimes ask for it to be checked by a mot station...

Right.. so you dont need to tell the DVLA?

if the engine change will alter anything on the V5, then yes, you do. but if it's the same size engine, same fuel type etc. then there probably won't be anything you need to change

If the engine has a bigger (or smaller) cubic capacity you'll need to change that on the V5. You'll also need to change the fuel type if that's different (ie deisel to petrol) and obviously wrote the new engine number on the V5. It's free to do - just fill out the changes, send the V5 away and a new one will turn up in the post.

Obviously if the engine is different to what the car came with as standard you'll need to inform your insurers as the change too.

V5

if you change the engine you should change the engine number on the V5

if you change the engine to one with a different capacity (cc) you should change the engine capacity on the V5

.....

Insurence

if you replace a 1.3 single point with a 1.3 single point.......theres no need to inform your insurence company

if you replace a 1.3 single point with a 1.3 multipoint injection (GT).......you SHOULD inform your insurence company

if you replace a 1.3 single point with a 1.8 20v Turbo.......you SHOULD inform your insurence company and they may want an engineers report doing (a bit like an SVA test that they do on new kitcars or imported cars)

Paul

p.s. "some" people change their engines for larger engines and don't inform the DVLA (V5) or their insurence company

they are naughty and there insurence would be invalid

Actually... Not trying to be picky, but if your engine number doesn't match up then you should tell the insurance company.

you don't give your insurence company your engine number in the first place.............so they have no number on the records for you to change

insurence company will only be interested if you fit a larger/more powerful engine.......cos they can charge more ££££

engine code is a matter for DVLA to deal with

It's not because you give them the engine number, but if you think insurance companies are doing anything to stop paying out. If the engine number does not match up to the chassis number, they'll use it against you. That's why a lot of online quote sites have the option of "standard replacement".

You'll need to re-mot the car - as the mot certificate will now be invalid,as it was the previous engine that was tested for emissions,exhaust leaks etc etc..

By the way,if you're considering putting a 1.6 in,get the calendar and calculator out - it'll be more expensive to tax with your updated documents,so it might pay to buy a years tax before you declare the conversion :)

I don't think so because only the chassis number goes onto the MOT details/certificate.

However, the tester can plug the engine number into the computer system and it will tell them when it was made and what the specifics of it should be

Yeah,but i was thinking engine size. My old mot certificate said it was a 1300 I'm pretty sure the copper at the desk might have something to say about that,if I'm showing my documents down the local nick,and i compliment that with an insurance certificate covering a 1600cc car
