I actually have a D series turbo log manifold from www.treadstoneperformance.com with a top mounted wastegate, and a HKS blow off valve, not sure of the particular model, it's the one that comes with the greddy kit for those motors I think. I also have an intercooler and all the piping. Also have a Turbonetics Evolution Wastegate with a 6lbs spring already in it along with a custom dump tube. I also have a T4 flanged 3" turbo downpipe. I also have the Downpipe from the greddy turbo kit as well. Let me know what you are looking for and we will work out a price!
