I hired Extreme Auto Works to perform a complete powertrain transplant in an older Japanese made vehicle. It was a very long experience--I worked with them for almost a year. It was a complicated job and probably stretched their abilities, but they responded well.

My one reservation was that it took longer than I would have hoped to complete the work, but in the end everything turned out great. I appreciate that they are willing to try just about anything. I would advise that you be clear upfront about what you want and when you want it. Other than that, expect the best.
