I used to have the same problome with my s13. I ran it for about a year like that it was imbaricing to have to start the car up at redlights and stuff. I never could find the problome with it I took it to nissan and they couldent help me eather. So what I ended up doing is a full engine rebuild of the KA24. I didn't have a turbo though. After that it ran fine never had a problome with it. Now I have it taken out of the car to move on to bigger and better engine like the RB25DET. . I hope someone else could help you more than me because an engine rebuild can be kind of expensive.
