What would the cost be to build a Nissan skyline gtr from the frame up for drift uses?

The Skyline is unibody so it doesn't have a frame, for one, but I know what you meant. Counting the cost of the car, it would depend on the generation, but cheapest for an R32 GT-R (A GTS-T would be better, it's already RWD not AWD, so cheaper) would probably be about $30,000-40,000, for an R33 would probably be $10,000-20,000 more, an R34 would be over $100,000, and an R35 would start at probably $100,000 minimum. And then there's all the spare parts that would be needed...Just do what every kid who saw Tokyo Drift does, and go buy a Nissan 240SX and slide it around until you hit a barrier 3 minutes later. That way you're not out all that money.
