Looking for technical documents

Hi
I’m looking for technical documents to help me convince the Danish automotive authorities that my mk1 is technically suited for forced induction. Can anybody help me?
 
I’m thinking that somewhere outthere somebody must have some kinds of documents - perhaps owners of the mk1 bbr turbo?!
 

What do you mean by technical documents?

I think there have been turbo/supercharger kits sold in Germany which had to be TUV certified. I guess that’s the kind of documentation you need.
As far as I know there’s no exact equivalent regulation in the UK - so long as the car still passes the same emissions test as it did unmodified, you can do pretty much what you like to the engine. I think its only if you more significantly alter the structure of the car that you need to seek type approval or single vehicle approval. I’m no expert though, this is just what I’ve heard.

 
TÜV is not enough. Unfortunately. It seems that the only way I can Turbocharge my car legally, is to somehow document that my car is techinally identical or superior to a similar roadlegal model with more power - as far as I know the only NA with more power than my 1995 1.8 is 1990’s BBR Turbo (130 hp vs. 150 hp), but I could be wrong. Anyway, that means that I need somekind of documentation that says “This model is identical/inferior to the NA 1.8, but has more power and is still safe.” This could be type approval papers for the BBR Turbo, or another NA thats more powerfull than mine.
Do I make any sense? If not I’ll try again - English is NOT my first language! :wink:

 
 
Type approval papers for any NA/mk1 that has more power than my 1995 1.8 would come in handy.
 
PS: Sorry about posting twice, couldn’t quite figure out how to quote 2 people in one post.

jimbobsquarepants may be able to help you out.

Que…

The BBR is before my time and i think before SVA so this is a best guess,

 I assume the vehicle was granted either National Type Approval or European Type Approval as a standard car, if the fitting of the turbo by BBR was carried out to ordered (therefore registered) cars, then the earlier post by Martin Young is spot on, you would just take delivery and that would be about it.

If however the conversion was done pre registration then a variation to the approval would have had to have been carried out by the importer (maybe under a low volume scheme) and the paperwork issued would have resulted in a revised Certificate of Conformity (The CoC is basically a statement from Mazda that states that vehicle chassis no:xxx is identical to the one submitted for test to the Dept for transport and conforms to the regulation for the territory in which you are trying to register it) This sounds like the document you are after but it still would not apply in your country, especially as your car is NOT an BBR.

You will not be able to obtain a CoC from Mazda, they do not issue statements like this easily, and then only if they have to for their own benefit, and they will never issue it to any un-official modification.

 My guess is the limited production run of the BBR would have been a pre-ordered, registered and then converted from new, and any surplus of these vehicles put into dealer stocks,  it is the cheapest and easiest way, i suspect the turbo may have even been fitted at dealers?

 I do not know the laws in your country but I would not except for the British market anything that has been modified away from standard, we use extensive model reports to prove conformity to an equivalent UK model, a one off would not meet these requirements.

 Sorry! [*-)]

 

I’m unsure about Denmark but I have certainly sold modified cars / kitcars to owners in other EU countries.

 IIRC there is a rule that if it has been registered in one it can be registered in all.

 Not ideal of you but may help.

 

 

Thank you for you help - I’ll keep trying to find a way to legally turbocharge my car.

 

 
It may be true for some countries, but unfortunately not Denmark - although a lot of people mistakenly think so (even some of the people who are checking the vehicles).
