But the fact is that i don't have the knowledge & necessary skills to perform the procedures described.. And unfortunately i don't think any of my local technicians or mechanics have those necessary skills aswel, mainly because the 300zx is incredibly rare where i live (Lebanon) and no mechanic has worked on one before.. Anyway i called this good mechanic who works on EVOs and i hope he could help me in this one. i didn't think that testing for a boost leak would be such a hard procedure..
