After a long time thinking about it. I believe mikes thread 472 vs vvt72 has me convinced that I too will soon be running a 472. I've done quite a bit of searching for new and used, and I can't come up with a decision on where to buy the turbo. I was hoping to find a used 472 83/.90ar but I've had no such luck so looks like I'll be buying a new unit. Anyone make any suggestions on the best place to get one? There's so many opinions based on my searches I couldn't come up with a good answer for myself. Thanks in advance.
