Hello... I own a 93 cym and it has 27k miles on the chasis and 10k on the motor but 27k on the turbos. I take great care of this car I bought a brand new crate motor for the car and had mazda install it because there wasnt anywhere around that could do it besides them. They did a great job, havent had any problems with it because the tech who worked on my car used to work on rx7's some time ago...

anyways... To make a long story longer, my turbos are making a strange whistle when I spool up and sometimes when I let off the gas... and no its not the turbo whistle that it always makes nor is it my bov... i know what those sound like. Its a strange kindof warped noise sounds like its coming from the valve that isnt the primary bov, not sure what it is called.

Any help would be much appreciated thank you guys very much!

 

Do you have a boost gauge if "yes" what's it reading if "no" go get 1 makes turbo trouble shotting a little easyer.
