I just picked a Mazda RX2 with a 12A in it. The motor is very dirty. I want to know what do I need to do in order to get it to shine. Do I just polish it or do I get Chromed? Thanks in Advance.

 

Get out yor elbow grease and start cleaning and polishing.. you will be able to polich the housings but you will have to paint the iron and acessories

 

So I shoukd start with a degreaser. And then polish with mothers alumnum polish. Or is there sum thing better

 

Are you contemplating turbocharging this motor?

 

you might want to ask around from someone that knows more than I do but if I were you I'd swap the rotors and the eccentric shaft from a 12a from a rx7. The rotors from those engines have a better design when it comes to the carbon seals. That and when you need to change seals it's easyer to find the apex seals for those rotors than it is to find the ones for the original 12a rotors. Just a thought

 

might as well go to a more comon engine like a s4 t2 13b or somthing.

 

I agree with that, but if he wants to keep the original twin dizzy set up i could see why he would wana use that block.

 

If you want to polish the housings, you better off taking it apart and check the guts, maybe even rebuilding it, send out the housings to the polisher. Just my .02 cents

 

My plan for her is to get her running. I have a rebuilt rx7 egine sitting in my garage just need ti drop her in. Next weekend am gonna by a engne stand and polish her out and post pic to see what u guys think.
