Insuring a highly modified car

So, are there insurers out there who will cover the value of highly modified Subies? I'm considering dropping a new motor and tranny into my 2014 foz, plus some performance mods and repainting her. But, I'd hate to be throwing that money away due to a fender bender that totals the car based on it's stock value. How do y'all protect against this when your car is highly modified? Thanks!
