URD SUPERCHARGER

so I found a "hardly" used urd supercharger for sale on craigslist. Guy says it came off an 05 x runner the only thing the kit is missing is the supercharger belt and misc. bolts and hardware. He's asking $1800 for the kit. Is that a good deal? What should I be weary about buying a used supercharger kit?

 

Devil's in the details. Since this is not a factory kit, hunting down the last few misc. bits can drive you crazy because some of them may be hard to find.

A new URD Mk III kit is $5800: http://urdusa.com/store/Forced-Indu...005-2008-Tacoma-V6,-Stage-1/product_info.html
Note the kit includes a higher-flow fuel pump (requires dropping the tank to install) and higher-flow injectors. Does the Craigslist kit include all this?
