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...

Uhhh huh? I simply said to start low on 6th gear 80 jus puts more load and stress on the motor. It can be done but I wouldn't do it like that. I wouldn't start a full run from 6th gear going 50 all the way to 170. It's simply too low. If I'm running wot I can switch from 5th to 6th at 100 or more.
I know the VQ motor pretty well, this isn't my first boosted VQ. I don't have personal experience with Porsche jus from what I read and a few friends so I can't comment on Porsche at all. VQ motor is nothing like Porsche.
