Both of these housings came from the same motor...

I used:

Carb cleaner
Wire brushes
High grit sand paper (for rough spots)
Polishing compound
Dremel polishing bits.. (went through many different ones)

And a little elbow grease, and this is the before and after.

Real nice.. I wanna do my UIM on my TII

 

thanks...

Yeah as soon as i get my butt off the computer and after i finish the other rotor housing, i might do an intake manifold...

How long did it take? Can you PM me how you did it? Thanks

 

That looks real nice dude.

 

I'll post how i did it if you want...

First i cleaned the housing thoroughly with carb cleaner (several cans).. I used two different types of wire brushes (small and large flat) and some greeny weenies in this process..

Once it was clean, i used a dremel tool with a wire rotating brush to take the top layer of the rough surfaces and make them smooth.. I sanded down the 13b mazda part of the housing with high grit sand paper...

after wire brushing the whole top of the housing with the dremel, i proceeded to use a polishing compound with polishing wheels for the dremel tool.. i went through a few of them doing this...

After repeating the polishing compound 3 to 4 times... this is how it came out.

What type of polishing compound? Thanks

 

looks great i'll have to do that when i do a rebuild . . .

 

I forget which type of compound i used, but it comes in a tube, and comes with the dremel polishing kit.
