legalities of Bike engines in minis or mini based kits

[Jamesy1974]

I have been through the old SVA process three times and whilst I have not yet experienced IVA I understand it is much the same only tougher/more expensive. Since I am into motorbikes and kit cars, I thought my next project could be a bike engined mini or preferably a bike engined GTM coupe. I have read several articles and visited Promotive's web site that details ingenious ways of making this happen using standard drive shafts and a custom reverse.

Heres the thing that confuses me - No one seems to make reference to the requirement for an IVA when the front mini subframe is quite clearly cut and modified to suit the bike engine. The FAQ section even says it was developed to be fully road legal.

A lot of people who modify minis seem to think that the IVA is something that 'only effects kit cars' but it is my understanding that these mods to the subframes will warrant an IVA test even if the shell is untouched. This being the case, I would imagine that there would then be many other areas associated with the mini or certainly GTM coupe that would be impossible to address once the need of a test has been evoked.

I am not necessarily trying to dodge the IVA but would like to know the reality of being able to get such a project on the road if I am going to invest time and money doing this. Comments especially from anyone who has completed a Promotive kit would be gratefully received.
