Changing engine size on v5c
Turbo Mini Forums

I can't remember how i did this last time (getting old)
I have had a look on the v5c and there is only a section for the engine no. and not cc.
I want to change the details from 848 to 1330, i think i had to send a receipt off last time.
Anyone enlighten me and tell me if i am about to open a can of worms?
Thanks Steve

Patina=old and knackered and won't clean up

Good luck!

They now need a receipt from the person that sold it to you and further evidence of the cc or something.

I changed the engine in my other mini and ended up giving up trying to change the engine number on the log book, and I havent heard anything else since!

Im sure Tim could sort you out though

Its a total nightmare!

As Nic said your need proof of the new engine siize to the exact cc. I sent a receipt saying mine was a 1293, to prove it was, and what did the DVLA do ....put it down as a 1275.

I couldn't be bothered to argue, its all pointless in my mind as long as the insurance is correct for the cc.

Definitely do NOT ask to have the engine capacity altered.It may have been sorted out since I was last involved, but there were all sorts of problems put in the way, including the assertion by DVLA that nobody ever made a 1275cc engine !!

Just make sure that your insurance company knows and maybe alter the engine number on the V5 (or transfer the original engine number maybe?)

do you have to have an engine number?

mines missing, and the 1100 is still in the garage with its own.

Only if someone official ever wants to check it.

I just wrote a cover letter explaining some bollocks about how I'd removed the engine from a specific donar mini.

Then got a garage I know to type up on headed paper that they have inspected and can confirm the engine is in the car.

6 weeks later got the amended v5 back.

Only did this last year.

Im going to try and change mine from 1098 to 1275 once its on the road. I plan to make up my own number as decking the block will remove the current number. I think I am in for a world of pain...

Minisport & Minispares can stamp you up a new engine number if you take your V5 and old engine numbers in :)

Its not the original engine so its not on the log book...

I did this recently for my Ginetta,expecting trouble, but they said they would accept a statement from a motor club official to confirm the capacity. They weren't bothered about the engine number which I couldn't make out for certain, didn't tell them that though. Our club registrar wrote a letter and the new V5 duly arrived, no problem!

would receipts for the engine boring and pistons of that size be enough?

I tried twice last year and gave up.

If you build and fit the engine yourself it is physically impossible to meet DVLA's "requirements" without getting someone to lie on your behalf as they insist on independant proof on letter headed paper (ie, a local garage) that they either fitted it or independantly verify it's capacity.
I wrote and asked how any independant garage could verify the capacity of an engine I built... I just got back another standard letter stating the same list of requirements, they hadn't even read the key part of my letter or just chose to ignore it.

I can understand why they want proof if someone was fitting a smaller engine to reduce the road tax but in 90% of our cases there is no change to the tax and if there is it's upwards !!!

Schrödinger's cat - so which one am I ???

i changed the astra engine from a 1.6 16v to a 1.4 8 valve turbo on lpg .
i went to my local garage ,asked them to write a letter stating engine no and engine size . i then took this to the dvla office in oxford ,and handed it over with the forms .4 weeks later , new v5 with correct engine size .
totally straightforward and easy.

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

TBH I think what Roberts done by taking the forms into a dvla office is the best idea, at least it save sending letters back and forth.

Better get there fast, they are supposed to be closing the local office to save money and increase efficiency. Irony if ever there was...
