The whole point of this being offered is to make the 4.7 hold up with serious boost on a regular basis. I found that a while ago while tuning my supercharged 4.7 and researching potential problems. It's definitely a bad a$$ short block!
I found mine on ebay a few years ago. It was the whole TRD system brand new in the box. They still come around from time to time. There are also other companies marketing cintrifigal systems for tundras that would be a fairly easy retrofit.
What part should I look for? Would the one for your 04 be the same as for my 05? Oh, and why the hell do I no longer get an email when someone posts a response in a thread I post in!?
