How exactly does it work if you just stick another lump in the motor, say your 2.5 is fucked on your sport, and you want another one in there, are there any markings on the engine that will give it away and let anyone (insurance inspectors!!) know that its not legit?
I ask as im very keen on sticking my brothers 1.8is engine in my 1.8 in the summer. I like my car, and its basically got everything an is has, bar the engine
Im figuring a or b, seeing as im currently under my dads policy as a named driver (im 17), so it would work out a lot better for me. Not too sure how cheap it would be if i start telling them its had a differnt lump put in it!
Obviously i dont want to be totally illegal.But if i can get away with (and i think i can) just keeping the 318i insurance, or at least taking out a new policy in my name and just say its an is, then i will.
