What type of budget are you thinking of for keeping the heat in? Having owned a few of high performance turbo vehicles in the past and I can say that heat wrap is a great thing.....in a controlled environment. The draw backs can be that it is fiber, and fiber tends to have absorbent qualities. I have seen on occasion vehicles having engine bay fires that were inadvertently made worse because there was heat tape wrapping the exhaust. It is a budget solution to keeping heat in the exhaust manifold to the turbo, and keeping engine bay temps down though. There is a way that is a bit more costly, having the manifold ceramic coated can keep the heat in, keep engine bay temps down, and improve the look, and durability of the manifold(s). Coating a manifold in and out can help reduce thermal variations in cast manifolds, reducing the likely hood of the part cracking as it cycles, and ages.
