Currently redoing my l28et intake and exhaust manifolds.  Does anyone know how hot the exhaust manifold and turbo get on a completely stock setup?  Im going to be painting the intake with 550 degree paint, is this high enough?  Was planning on painting the exhaust with 1400 degree paint and possibly wrapping.  is this a concern?  Will the manifold with wrap get above 1400 degrees.  also any thoughts on a turbo blanket causing extra wear on the stock turbo?  Really dont want to send the manifold out to get professionally coated, cant afford to.  Has anyone made a custom heat shield to go between the exhaust and intake?

Don't wrap, blanket.
Surface temps can be red hot. To brilliant yello-white hot... Anything short of ceramic coating will likely just burn off if you boost for extended periods.

Thank u for the reply. What I've decided is to put a thermo tec blanket on the bottom of the intake with it reflective side towards the exhaust. It's rated to block 2000 degree radiant heat. I painted the exhaust and turbo with 1300-2000 ceramic paint.
