I was wondering if anyone on here has ever polished their turbo, manifold, valve cover, etc.. with a dremal. I am thinking about doing this and was looking for some pointers. Any and all advice welcomed. Pics would be excellent! Thanks.

You are going to need about 486 man hours, 357 grinder bits, 513 sanding bits, 748 polishing bits, and a whole hell of a lot of patience.

It would be cool if you could pull it off, but damn. Dremels aren't meant for large jobs like that.

BTW nice avatar!! Hahahaha.

Thanks for the compliment on the avatar. Anyway, how would you go about polishing these parts? An angle grinder, with a polishing wheel? The only reason I said use the dremel is because I already own a dremel and I don't own an angle grinder, but I can prolly find a cheap one for around $20. what do you think?

Dr.Boost

The bigger the better. You have a lot of material to polish. You could use the dremel for the hard to reach parts or the smaller parts.

i used a wire brush and a circle grinder to polish my turbo. and i've used dremals and sandpaper flap'd bits to port/polish...

the best way to polish a valve cover is, go to a home depot and buy one of thoes drill acessories that are round and have small strips of sandpaper glued to them, you get the idea its like a surfacig tool that attaches to your drill, you can find it in the same isle with all the other sandpaper products, ne way, use that with a drill, i did my valve cover with it from a D16A6 it turned out good, took about 4-5 hours and thats with sanding the big H off and the other company written BS.

I used a dremmel to polish out my wastegate, and the intake/exhaust manifolds to the engine.

It does take a long time to actually 'indent' into the surface, a die grinder is by far superior but unfortunately my air compressor can't keep up with it.

There was a flat bit I found worked the best, I am not sure what it was called, I think its a metal grinder meant for cutting screws and such. If you use it at 45 degree angle and pull slowly you can tear a good amount of metal out in each stroke.

All in all though, for efficiency, you would be better off using a die grinder!

fine steel wool works great for polishing and cleaning chrome and aluminum. seems like steel takes a little more elbow work. $5 for a pack of like 10 at homedepot.

here is a pretty good write up on the whole process http://www.rx7turboturbo.com/robrobinette/polish.htm

my air comp. doesn't keep up either.. SUCKS when you're trying to port out manifolds/adapter plates... 12 seconds of grinding.... go grab a snack for 2 min and come back .... repeat, repeat.. lol.
