DIY Heatshields In Progress
I started working on a heat shield for my manifold/turbo. This started as a heat shield from a 96 Kia Sephia which had a BP 1.8 from the factory. Being a FWD car, the manifold it had pointed straight down, not down and back like a miata manifold.
So I cut it up trying to massage it to cover the manifold and turbo all in one piece. Gave up. So I started cutting till it fit right. Currently has 1/4" clearance anywhere on the manifold and wraps around it pretty good. I'm gonna build up a spot on top where it's missing. I'm unsure if this will be a manifold-only shield of if I'll try to make it cover part of the turbine as well.
Any ideas on where to go from here are appreciated. Got a bad headache while working on it and just gave up. Will probably work on it more tomorrow. I would love to make this look OEM, though it's hard. Perhaps There's some color that looks like metal that I could paint it.

Also not sure how to bend the metal to cover the turbine. I can bend it one way, or the other, but not both ways. So I'm still powdering this part too.
I may stop on this shield and start on another tomorrow instead. I'm want to put a shield behind the air filter to keep heat from the manifold/turbo away. This will just be a piece of metal bent up to fit, with a hole for the air filter pipe to go through.

don't forget about your oil feed line, I did when I was messing around with heat shields and got pissed and stopped. I like the OEM look, when finished touch it up with some silver engine enamel
also while doing some searching, I ran across lazzer's heat shield and thought it looked dead sexy and might give you some inspiration

Funny aside- I was showing my turbo setup to a friend that works at autozone today and some guy walked up and thought it was an OEM turbo setup.

Do you want to build one or buy one?
Buy: Xcessive T25/T3 Turbo : Heat Shield
Build: How-to: DIY turbo heat shield - HybridZ
That homemade one is cool as crap. I might leave the handles on it just to screw with people.

no, I'm not.
I'm not the only one who feels this way:

In terms of metalurgy, red is not real hot. Red for steel/iron is around 1100F, and that's within the scope of a stock NA engine. But, it is still impressive when you look at it.
Regardless, ceramics are very nice, as your choice of colors is usually whatever the ceramic color is or rust red.

Corky Bell is a smart fella, but he is wrong here... Mr. Bell believes that since the sucker still glows, the coating can't be insulating any better than without it? Is that even an argument, empirical, or otherwise?
It can't stop ALL the heat; if it could, entropy could be disproven, damn...
I'm looking for posted specifics on this online with little help, but I know for a fact that coated turbine housings and manifolds increase performance; this is how the coating industry got race teams of all flavors interested in the first place, some 30 years ago. Apparently the government was at the same Kool-Aid party, they've used it on all sorts of applications both public and secret for the same amount of time. Hell, IIRC the military pioneered the process for coating before the private sector got it; but what do I know?
I'll keep looking for something closer to this application and post up what I find.
