you sure you are'nt trying for home insurance and they want a structural survey?

normally if its a standard swap then its not too much bother... and seeing as its just a CVH with a turbo taped to the side, i dont think its too much bother...

you could try and just say its had a turbo conversion... and see what they say... it sounds like they did'nt want to insure you! i can see why they would want reports if you had space framed it or something, coz they will need to know structural strength... but its a fairly standard swap!
