What Spark Plugs?

What was stock and whats recommended?

Don't remember what is stock. My car sees nothing but NGK3330's. That's the most reccomended plug for me. Set the gap at 29 and you should be set.

Since you got a turbo you'll want a set of coppers, either NGK's or Autolites, NGK number is BCPR7ES and the Autolites are 3923. If you don't want coppers for some reason get a set of Denso Iridium's, number 5313 IQ22. As for the gap...
