I did a thread on this a while back for my 1995 240sx. I quickly changed my mind. Most shows that had experience were looking to cahge at the very least $4000 plus the engine and such. It is a very expensive process and lik eyou said, finding a shop that has experiance is difficult, I heard a lot of horro stories of shops saying they know how, but then not being able to finish from lack of know how.
