I just bought that same system on ebay for $220 shipped, I bought it from coolingmist directly and it's brand new.
I was bidding on one and lost the auction, then I got a second chance offer with a Buy It Now price of $200. Didn't expect that.
Anyway, I already ordered a .82 T3 V-band 6262, 8.5CR CP pistons, Manley Rods, ID1000 injectors, Mazworx Head Studs, GTiR main bolts, VE head gasket, ACL race bearings, etc.
The only relevant part I haven't bought is the fuel pump, I have a Walbro 255 but I will likely get either a DW300 or an Aeromotive 340. The rest is just fabrication. I'm also contemplating getting a Turbosmart eBoost2 boost controller but not sure yet.
