Hey Guys,

Just picked up some 3FE parts for my 2FE conversion and I am now moving into my cleanup phase. I am uber paranoid about heat now as my rig has had many heat related issues. On my rebuild I just want to manage the heat as best I can. I am wondering what I can/should ceramic coat and what I should Powder Coat. I am definitely going to be doing the exhaust manifolds but what else? Can a coat the intake manifold and/or the EFI manifold? How bout the exhaust covers? Pic below highlighting parts I am looking into. Thanks in advance for any help as always.

Doing the intake manifold would be a waste of money. The shields that bolt to the exhaust manifold do a very good job of retaining the exhaust heat, so ceramic coating there wouldn't be necessary. If you really want to pretty it up, I would look into some high temp paint or powdercoat for the heat shields, but remember that manifold puts out a ton of heat under the shields.

Honestly as long as nothing's really corroded I would leave it as-is. Just give it all a good cleaning and call it good.
 
I coated my turbo and exhaust manifold with ceramics and had other parts like the timing cover, rocker cover, pushrod cover, oil pan, intake , and a mess of other stuff powder coated. I like the way it turned out and it should last for as long as i keep the truck, unlike spray paint.

Thanks for the pics baxter.

Few reasons I want to Ceramic Coat stuff.

1. As I said, overly sensitive to heat.
2. Extend the life of the parts. I know these things last forever but all the parts I have are already 20+ years old. Would like to breath some new life into them. The heat shields go bad all the time. I see people always looking for them.
3. I do want to "pretty" it up. I live in Cali so when it comes time for smog testing having a "pretty" engine bay will only help on the visual. Especially since I am doing a hybrid motor.

Also thinking about powder coating the air box and some other parts like that.
 
Man you guys are being hard on him.He wants to do a nice clean job and your giving him a rough go at it.
But if it were me i would ceramic coat the exhaust it does help with heat >>

Hey don't look at me I offered the man real advice based on my opinion....
 
I used a DIY ceramic coating (Techline) on the exhaust manifolds and lower intake manifold on my 2FE, then I painted over those and the heat shields with a silver high temp paint (ceramic coating was black, someone pointed out quite rightly that black isn't a good color for heat control..)

In direct sunlight yes, but in the dark engine bay it may not matter.

Depends what you mean by heat control. If you're looking to shed heat from something you want it flat black. If you want it to retain heat it should be white or ideally metallic (silver.)

Opposite for collecting/picking up heat. (Light/white clothes in the summer, dark clothes in the winter.)

So if you want exhaust manifolds to maintain the heat inside Matt has it right.
 
You can powder coat pretty much all the parts on the motor. The exhaust would have to be silicone high temp powder (1200 degree) and it is really kind of a stop gap between high temp paint and ceramic coating both in quality and cost. I have used it quite a bit with good results but it is a two or three year coating, ceramic is really the choice if you don't mind the cost. Regular polyester powders for everything else. Mostly you will be doing it just for aesthetics, but there is nothing wrong with that. Price from a quality and fair powder coater is not that bad either. Read up on "blackbody radiation", interesting stuff. I did the supercharger on my 1FZ-FE 80 series in black to try to radiate heat out if it. On your exhaust, you may want silver to keep radiation in the engine compartment to a minimum. Maybe the same for the heat shields. Dark on the valve cover and block would push more heat off of those parts than absorb since they are a higher temperature than their surroundings. HTH

I'm not really a scientist, but I did sleep at a Holiday Inn Express last night.
