Whats the deal with Eaton M112?

I have been looking for blowers and have found lots of Eaton M112's off of 03/04 cobras. One I can get for like 500 bucks. Whats up, are they crap? Why are they so cheap. Torch teck makes a conversion intake manifold for like 1300 but it seems like no one uses the eaton. Why, what problems are there?

Thanks
 
They're not known for being big power producers like the KB and Whipple and at higher boost levels, they're not very efficient, so the air charge gets pretty hot. That being said, I'd still run one of the Tork Tech kits, if I had a 4.6 2V.

Are they still saling the 2v kit?
