Forgive me if this has been dealt with before but couldn't find an answer in older threads.
What is the max the boost should read for my '02 gu3 3.0L? Have just had a reco ZD30 installed. Done about 1600k. Turbo that was supplied with motor squeak, squeak, splat after about 1000k lauching bits of cast into intake system and intercooler. Since replaced it with genuine Nissan Garrett turbo.
Going by the boost gauge it reaches >20 psi when the foot goes down, levels out about 10, then drops back to around 5-3 psi.
Appreciate any wisdom on this. (EGR is blocked also)
