I'm trying to decide on the color scheme for the engine. The car is a pearl orange that will be impossible to match with powdercoat. I was thinking about painting the intakes and the irons the same orange as the car, and powdercoating the housings and throttle body "almost chrome." I'm a little worried about the paint holding up to the temps and "browning" since it won't be a high temp paint. Anyone have any experience with this?

 

Done several custom car applications with body colors, the housings really do not get much hotter than a hood would see on a hot sunny day in the south after a hard run, except for near the exhaust ports and you do not paint those machined surfaces and they are normally hidden anyway... the outboard side of the intake may see some discoloration only because of it's proximity to the turbo unless you fabricate a really nice effective heat shield, oh and do not clear coat it... by the way neat ride...
