HIP was on Ebay this summer, but their site says its being updated. If you search on NICO, there's a link to the old Ebay auction. IIRC, the kits normally go for $2800.The BD and BE stg 2 kits look very similar to me, especially the manifolds. BE includes a Z32 MAF, while BD doesn't. But BD's kits are sale for $2550.BE comes with a real Tial WG. I think the BD kit uses a knockoff.
All these kits use a T3/T4 57 trim. You can find maps at
