Noteifying dvla about engine swap.

[zaust]

What's the best way to do this. Change the cc's and engine number's on the v5 and send it off, or will the car need to be inspected and tested. ???

[Jhonno]

Don't bother

[zaust]

Thought about that, but don't want to get caught out.

[StuBeeDoo]

Don't bother

Depends what engines you're swapping. Something like M20 for M20, I wouldn't bother.
M20 or M40 for M50 or S50 I'd do as it looks obvious. Just change the engine number and cc's on the V5 and post it off.

[Jhonno]

Someone here tried it and it turned into a complete ball ache..

How are you going to get caught out? It is insured properly, still falls in the same tax band, still MOT's the same..

[fuzzy]

the mot man told me the last time that technically he should fail it as its not as his computer is telling him and it effects the emission levels. he passed it anyway and told me if i got stopped the engine was changed after the mot...

M30

AFAIK the DVLA will only want to inspect the car if it goes into a lower tax bracket.

As your tax will stay the same for the m30 there shouldn't be too much messing, as above send off v5 with new capacity and engine number.

Did mine OK, just sent the reg doc off with new capacity and engine number. Never had any problems and just went through MOT OK.

That's what I needed to hear/read, Thank's fella. will be sending next year....

Correct me if im wrong but the year engine is from is what affect mot emmissions rather than year of the car itself? for example if the car is a 1995 model and your swap in a pre march 1992 engine the mot emmissions level is based on pre march 1992? If so its more forgiving as you can do away with cats and allowed slightly higher emmissions but currently fall under pre march 1992 tax bracket too making it cheaper to tax?

[goosiegander]

And the same here, posted off with new cc and eng no. No problems 2 mot's later

[monkey]

i had no problems just posted it with new numbers and cc , it even came back to me within 2 weeks

[fuzzy]

And the same here, posted off with new cc and eng no. No problems 2 mot's later

you wont have any probs if youve informed the dvla but if you go for an mot and the computer says you still have the standard engine....

Belive me they won't even check under the hood where I go

[fuzzy]

theyve no reason to look under the bonnet but the emission levels might be different from the standard engine...

I checked with MOT man when I took mine in, emissions are related to original registration / manufacture date of car.

[Jhonno]

Emissions are down to whatever is older, the car or the engine..

[Jhonno]

I'm pretty certain all cars before 1992 had to meet the same levels..

[zaust]

Allowed 220 co's and hc's of 200 on a 325 so it won't be an issue at all.

But i'm sure if it was above they would use a different motor to get the safe reading for me......

[Jhonno]

..

So wouldn't matter what car they used..

[fuzzy]

and when its a 1991 car and an engine of undetermined age that uses parts that span both sides of 1992? 4wd block ,manifolds and turbo from 1992 on... 2wd head,ecu, gearbox 1986 -1991 ...
would they go by cars age or the oldest part of the engine?

[Jhonno]

Well the block is pre '92..

[Jhonno]

the car is pre '92 anyway

[zaust]

Mot is not an issue lol.


Anything pre 92 is allowed a silly amount of co's that no one would run there car at unless they have a desire for bore wash. or have 600+ hp

[ShakeyC]

I tried to find out today but VOSA are just a bunch of ex bus drivers, miserable unhelpful and no real knowledge or skill of anything they ment to do

From my understanding if you can prove via engine block number and garage reciept to help ID origins of the engine you inform DVLA of new engine number, cc and fuel type you get your log book back and all is well and your emissions is calculated from those factors.

What i was told by VOSA if you change engines you must do the same and from car registration date, engine number, cc and fuel type is used to put you in correct class, if pre 92 engine number your allowed higher emissions and no cat and slightly lower tax too.

Fuzzy in your case I would use your engine block number to ID your cars emissions data if its pre march 92 I would change V5 over and pay less tax and be allowed more smoke and no cats.
