can you use 2 fount rotors to rebuild a motor ?

or do you need to have a back and fount rotors
i can't find a good back rotor from any where

 

they are the same as long as they are both S4 or S5, and both either non turbo or turbo. just make sure they are close in weight. can't give you specs on that.

 

fount?

 

Yes and no. Yes, but the emissions, if you have to pass them, will be harder to pass due to the passages for the *Port Air* that comes from the acv. Butttttt you don't have emission testing, do you?????? So I guess that means yes. What year engines are you talking about????

 

HAILERS you're thinking too hard. he said rotors not rotor housings

edit: wtf. that top face isn't even in my post LOL I have no idea where it came from LOL.

 

Got my head up my dark place again!

 

I guess you could, just make sure the weight code which is A-F i think is not more than one letter off, for example, you have a "F" code weighted rotor, you can use a D, but I wouldn't use a A or B.

 

you mean an E? (isn't a D 2 off? )

 

holy crap, I really am brain-dead after a day in the sun. Yeah I mean if it's an "F" you can use either a E or G. Thanks for the correction

 

Mazdatrix has both rotors as the same part#.They say both rotors are the same on the 13B.Just make sure both are from the same year group(86-88 or 89-92).
