If Nissan had offered a V8 Z with 450 ft/lbs of torque, I'd have happily done that over boosting the Z. Plus, it's not like you can't boost a V8.

And the guy who traded the ZR1 for the M4 doesn't miss it one bit because the interior of a Vette is really sad, especially when you pay 100k for it.

True. It's all preference. I would rather a factory turbo engine. After being around the Forced Induction crowd, I'm ready to join. To me, the bang for the buck factor is factory FI. Lag is all about the equipment you use and how it's tuned. Factory FI cars have little to no lag and very nice torque curves. The M4, for example, peak torque comes early on around 2k and stays pretty flat throughout the rev band.

And yes, the interior/build quality played into it, but he said it was just the overall driving experience. I asked him specifically about the engine, how it was going from a giant blown v8 to a TT I6, and he said that the only thing he missed about it was the instant low end torque vs the BMW having to spool up a bit. Just his opinion though. I don't own either so I can't comment on it.

bimmer's are tuned that way... i know the 335 peaks around 3k rpm with majority coming in between 2-2.5 range. the car idled in low 1k range. In all honesty I did not notice any 'lag' in the get-go but if shifting around 3k rpm it would feel like a long shift/power response compared to shifting at say 3.5 or 4k...

I think most Factory FI cars are tuned that way, especially the more 'civilian' ones. My good friend has a 2010 GTI 6MT and his peak torque comes in at 1700rpm and is pretty flat through 5000 or so. It does fall flat up top so winding it all the way to red line doesn't do that much. Once he added intake and APR stage 1 tune, it really woke up.

Yeah, that's the problem. Manufacturers don't think customers want to deal with a low boost threshold, so they use undersized turbos. They feel peppy down low and die up top. You can run more boost out of them, but they end up just blowing hot air once you run them out of their efficiency range. I'd be happy if they put in a factory turbo motor with the headroom to swap out the turbo without building a motor. Some lag is unavoidable, since there is many feet of pipe and an intercooler that must be pressurized before the motor sees positive pressure.

the 14 price drop hurt us all lol

:crying:
:shakes head:
I didn't realize the front bumper change until it was too late.. I need a fang transplant.

If they follow the new coupe Q60 route then, ""The new Q60 is going to be a big pivot point for the brand," de Nysschen admits. Meanwhile, a new V-6 family is under development to replace the coarse old unit that's done sterling service in dozens of Nissan and Infiniti models over the years. It'll be smoother, lighter, more refined, more efficient, "and there's plenty of headroom for turbocharging," adds de Nysschen.

The fangs are cool. I guess I like my front bumper like I like my women, clean shaven down low :yum:

This is actually great news, the vq37 without being boosted it very linear and coarse. It doesn't sound like a sport car either you have to spend $1500 on a cat back just to make it sound proper. Still doesn't sound as good as that g35 purr.

Nissan / infiniti desperately need a better v6 for mpg, also turbo 4 options from mercedes

No clue what you're talking about, but if that's someone's screen name it sucks.

Sorry, a lot of the things you're posting and the phrasing brought him to mind. Never mind.
