They are a much more expensive turbo, retail at about $2100 each. They only have external WG currently & there is no timeline for the IWG to be released. Add the cost of a pair of external WGs at about $300 each & you are at $4800 before custom manifolds , down pipes & turbo inlets at the minimum. If not custom turbo outlets & maybe oil feed/return lines as well. A Complete kit would cost $7000/$8000+... That is more that you can buy a complete car for & I'm betting the market is pretty small in the Z32 community. If you are interested & have that budget, hit me up.
