hey guys,
i just had my 850's bored out to 1300 and the injector on the left was had the black sleeve broken off. will that be an issue, will i need to have it fixed somehow.

 

Thats your fuel injector screen and should be replaced. should not cost to much.

 

does mazda have them?
where would i get one?

 

Try emailing some of the injector cleaning companies like Witchdoctor or RC Engineering.

 

They pop off the injectors with a little work, so if you have an old 850 (secondary) laying around you could transfer it over to the 1300.

 

I had the same issue as you. My injector was missing a small part. I sent them to RC to have them bored to 1300.

RC Engineering replaces all of the parts like O-rings etc. after they've cleaned and/or bored the injectors. Give them a call, I'm sure they can get you what you're looking for.
