I went to a Toyota dealer some days ago. I was talking to a salesman there regarding engine reliablity. What I found I out is high-rev N/A engines are hard to modify with tubo/super charge kit. Also, they don't last long (like 5 years) if they keep getting high rev. So my question is how reliable a NA engine is? Said like Celica GTS, Honda Type-R and WRX's turbo? :thinking:

What's BMW VANOS system? And what is the different between Double VANOS on 760 and normal VANOS? Is that very different than our VTEC/iVTEC?
