Turbocharger detailing?

I see you guys tackle some pretty rough stuff around here, but how about this:







As you can see, the turbo has a combination of rust and corrosion. The down elbow really isn't my biggest worry because I will be fitting a new one on it anyway, but the rest of the turbo could use some TLC. Does anybody have any tips for handling something like this? I'd love the look of a clean aluminum compressor housing, but the shaft and turbine housings might just look better with some high temperature paint that has ceramic in it. Any tips would be greatly appreciated as long as they don't put down the turbo. This thing operates like a dream... it's just a little ugly. :chuckle:
 
only thing i can suggest is to sand with high grit sandpaper and then use some compound on it. paint on the exhaust housing is a nice idea but that thing just gets way too hot for any kind of ceramic paint.
 
a rough sandpaper or a dremel to get some of the rust off, a lighter grade sandpaper next, and then switch to a metal polish to finish it off. It should be blingin' after that :D what is the turbo from?
 
The compressor housing will polish up nicely, but the exhaust housing will always rust up due to the high iron content in the casting. Get it Jet Hot coated.
 
Middle pic: looks like cast aluminum, two ways of doing it the fast way aluminum brightener which is an acid and the other is an grinder machine with a polishing bonnet and using polishing roel (spelling?)
 
The turbo is an older style Holset HY35W off of a Dodge Ram. It will be going on my TurboCoupe in place of my IHI sometime soon I'm hoping. Now, is there any way to just clean up the corrosion? I really prefer the regular cast aluminum look as opposed to the polished. Maybe Aluminum Brightener would be the right choice for me on the compressor housing then. I prolly won't be doing the Jet Hot Coating either because I was looking on their site and it claims to LOWER the temperature of whatever it coats... Totally not what I want going on in a turbine housing. ;) http://www.por15.com/product.asp?productid=128 Might be a smarter choice for the turbine housing, but I haven't heard of anybody using this stuff yet.
 
Jet Hot lowers the external temps of what it coats. It will NOT decrease internal temps inside the turbine housing, which would in turn decrease the efficiency of the power of the turbo. Lower external temps equal lower under hood temps, which is definitely a good thing. I've had just a bit of experience with forced induction applications. :)
 
I just gave Jet-Hot Coatings a call and their product sounds really nice and durable, but it would cost $100 to $150 to have it coated. I'm not sure if they thought I was talkin about the whole turbo or just the turbine housing. If it was only the turbine housing, it wouldn't be THAT bad, but it would put a little dent in the wallet. I'll be looking around for some possible cheaper alternatives before I go to them. Thanks for informing me of them though! Do you have any pictures of their work? I was thinking of going flat black because I don't know how well the other colors would look. And if you know of any other coatings, don't hesitate letting me know.
 
GoFastTSI is right, you want to minimize heat loss from the turbine (i.e. keep the outside temp lower and the inside temp hotter) to maximize turbocharger efficiency and reduce under hood temps.



Techline Coatings makes DIY ceramic coatings, including an extra high temp coating specifically for turbochargers.





PC.
 
I'm liking Techline coatings. I've talked to many people who have had experiences with them and found them to be quite strong enough for my application. 50 bucks for 8 ounces of the stuff? I'm loving that price! Now to figure out exactly where I want to go with the compressor housing... :)
