it probably has to do with the bov, not being re-circulated back into the intake... ussual for turbo motors.... but it shouldnt kill the motor... does it do it even when you dont spool the turbo?

Sounds like a boost/vacumm leak.

so i checked all my vacuum lines and they are all good and as for the bov i will recirculate the air back into the intake to see if that fixes the problem..on my bros 99gst he had the same problem with his and he did have his bov recirculate back into the intake and still had the same problem untill he put in a fuel rail and fpr then it fixed the problem.. would that be the same thing with my ka?

Its because your using an atmospheric blow off valve.
