I would think that a recentable to very good condition R32GTR will cost around $30-$40k, I have seen many shit R32GTR around 25k and they are shit, 98-92 early model, engine, electrical, problem and it will cost u around $6-7k to replace the engine anyway. so why don't just buy a $30k good condition GTR? If u lucky enough, maybe u can find a 93-94 later model
