Heat wraping exhaust manifold (will it crack?) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I am having overheating issues since I put my FMIC on my s13. I have orded another fan to run a dual setup and contemplating getting a 2 core radiator. But for now I want to try inexpensive fixes (i.e. 2 fans and heat wrap)
I know the benefit of heat wraping the exhaust manifold of a SR but I am worried about cracking the manifold under the heat. Will the stock manifold hold up to heat wrapping.
BTW I did a search for "heat wrap" and nothiing came up so I assume it's a non-factor. But any and all input would be greatly apreciated and any advice on reducing heat in my engine bay.

Theres a couple of routes. Or any number of variants.

1) Get some sheet metal and make heat shields.

2) Ceramic coating of mani and turbine side.

3) Vented hood (ONLY IN CERTAIN PLACES)

4) Bigger cooling radiator

5) Fans.
