I purchased my full Ver. 8 6-speed swap from JDM Racing Motors and had a great experience.
Robert was careful to determine which parts I wanted/needed, then helped guide me through the prices of various options. He then coordinated with their Virginia warehouse, which had all that I needed, so I could pick it up. I ended up needing a couple of parts that I didn't anticipate, and JDM Racing Motors followed through to help me get those parts.
There was never a point where I felt like I was on my own. I just called Robert and he helped me out. I am a happy customer, and plan to buy more from them in the future.
