Fabricate a heat shield for the manifold/turbo
Seal off any spaces where frontal air could get around and not through your radiator. The heat exchanger needs a pressure differential to move air across the core.
Install fender liners. Wheel wells are high pressure areas and hurt your the bottom line of your radiator frontal air pressure differential.
Do not raise the back of your hood up for "cowl induction" unless the induction across the entire length is sealed to the engine air intake. The area near the back of the hood/bottom of the windshield is a high pressure area.
Straighten your radiator fins with a pick.
Save money.

Seriously though, that's the best advice. Making the best possible use of the existing radiator is a good idea, and a quick and dirty radiator duct between the bumper opening and radiator is usually a worthwhile improvement, along with blocking any other open areas (like that gap between the radiator support and the radiator).

An extra fan on the back side will just reduce the work that the fan on the front does, adding only a little improvement over a single fan on the front (or the back).

Ok, a lot of good advice. I’ll look into getting a head shield fabricated for the manifold. Due to the reasons Fabrik8 mentioned, I wasn’t too keen on wrapping it. I’ll be adding some duct tape to my passenger side fender lining b/c I cut the bottom for my cold air intake on my previous engine. Will see about maybe running a splitter or using another method to help reduce open spaces and channel air through the radiator.

I think you should ceramic coat it if you aren't going to wrap it. That's a pretty short manifold to wrap, and ceramic coating will reduce radiated heat by quite a bit.
