Foam tape works very well for filling the gaps between the fan shroud and radiator. Sounds like you have a good cooling setup now. I ran a 180* in my 1G and had no issues with it over-heating; if this doesn't fix your problem then there are likely other issues to dig in to as well. You could try ceramic coatings on the exhaust manifold and turbine housing, a turbo blanket on the turbine housing, and most simply, running as many of the stock heatshields as possible (appears you already have one on the ex mani which is great).
