What intercooler are you using? If you are using a normal intercooler and not a same side inlet and outlet like the Hahn you could turn the turbo around. The down pipe on the driver side and outlet on the passenger side. Your down pipe is not going to be anywhere near as big as your compressor cover. If you don't want to do that then You could run a Half radiator and get another flange for the head and use it as a spacer and then make another tube to relocate where the wastegate is to hopefully move it from the upper rad hose. Another thing, if you not going to use heat wrap on that manifold I HIGHLY suggest that you at least send it out for Jet Hot or even better Swaintech coating. Your under hood temps/IAT temps are going to need all the help they can get.
