In my opinion, since I already owned a GT3-RS MK2, I have a very high expectation of a sports cars. Believe me that I paid $154,752 OTD back in 2009 for that monster and I could drive hard all day long at 130 mph + , taking corners at 1.3+G at 8000 rpm with ease and a piece of mind. By the way, my GT3RS consumed about 1 quart of oil every 800 miles during medium to hard driving. Porsche stated that it was absolutely normal because the engine were meant consume oil ... tremendously just like that.
Now, I am sure this 370Z can achieve at least 90% of that performance if properly and professionally modified , and better yet, it will cost way less than what I paid for the GT3-RS back then. The VQ37 engine bottom end is much better than most people think. I don't believe that there is any problem with the stock bottom end to spin at 8000 rpm. However, the weak link is the VVEL camless ladder assembly. Now, that is the very reason why I do not raise the factory red line to 8000 rpm. I still leave it at the cutoff point at 7600 rpm.
Like I said, the only flaw of this whole design is the excessive heat generated from the engine... and excessive heat does kill engine and other components HARD. If you can liberate the heat as what I have done, this engine can take very good high rpm and load abuse ( up to 7500 rpm only ). The engine may not last as long as my GT3RS MK2, but it will be pretty close...
