Is it leagal in UK to put another more powerful engine into the car?
I see many conversions f.e. MKI escorts with cossie engines and so on.... So is it leagal?
In my home country we can't put the engine in if it has more then 30% more power then standard engine fitted into that car
Does anyone know the route how they do it in UK...and whats the problem with Insurance, MOT and so on?

Thanks
