Waiting to Inhale VQ37VHR tuning /modablity

I have to add while i'm up and cannot sleep yet AGAIN... the Nismo is B class, and 370z is C, it doesn't specify "all" whereas the 350z does say "all".

IMHO the Nismo has been shown that it isn't much faster, if at all than a sport package Z... perhaps adding a better set of pads and oil cooler (as already stated) any 370 could or should be moved to B class.

People can say what they want, but coming from 2 Evo's (an 06 RS and 08 GSR) stock for stock the only thing that helps the average Evo driver vs the average 370z driver in the 08 and above is the VERY sophisticated Super all wheel control that can turn any average driver into a hero. The 03-06 still gets a lot of help from the AWD and it's a blast to drive as well don't get me wrong, but I think that the 370 has more ability than where it is "classed".

Reread my post about tires. Being able to go wider makes a ton of difference. The guys in nismos are out-tiring the nismos by 20mm (usually more). Even the regular z has a huge tire advantage over the rest of it's class

Red_Zed. You keep saying the Z can't compete with the Evo and STI. Both of those cars brake and handle better then a Z? O-60 and 1/4 mile times are better? They pull off better skid pad results? I'm pretty sure the Z was designed to compete with the cayman S. Which means the EVO and STI should be no prob. Not 2 mention your not touching a good evo or sti for lestt then 38-40K. My Z was 34

If you think you can beat them, get out there and do it.

You can comfortably pick up an Sti for 35k otd in va(3% tax). I know because I almost got one instead of the wrx.


Yes, it was designed with the Porsche as a benchmark-- and it benchmarks well against it...real numbers are less favorable, and the real dynamics are crap.

red6spd

Well I know for a fact I'm faster then a 09 WRX Stage 2 (friends car) I'm not going to get into what kind of racing we did. Oh and I only had an intake at the time. As for turns, braking ETC, why would I have to go out and prove it? Are they better then the Z or not?

So you did a 50 pull? Not exactly a good way to judge a car.

The reason you would have to go out and prove it is the other cars embarrass the z in every event. Guys that slap 305 r comps on their nismos get beat by Evo's all the time on a real course. I put 1-2 seconds on a stock z in my wrx.

red6spd

Slower then a 50 pull, but funny you should say that. You sound like the typical Subby owner who only wants to run from like 20-100 LOL. I just gave you numbers from a mag that had pro drivers drive the car. Just cause you see an EVO kill a Z on a course does not mean its a better car, just means he might be a better driver. And you put 1-2 seconds on a stock Z huh? Guess then Z guy cant drive, dont get all hyped up over that 0-60 time of 4.6 seconds. CarAndDriver admitted that the only way to get those numbers was a drivetrain killing redline clutch dump.

You do realize that the WRX is a "D" stock car correct?

SCCA Solo Car Classifications: Stock by Class

That PDF page won't open for me so I had to go by this.

Here are some stats I found from Motor Trend


2011 WRX STI Sedan

Curb Weight-- 3262
0-60-- 5.0
1/4 Mile-- 13.8@97.6
Braking-- 60-0 113FT
Lateral Acceleration-- .93g
MT Figure Eight-- 25.5 sec @ 0.73 g (avg)


2011 Nissan 370Z Touring

CURB WEIGHT-- 3362 lb
0-60--4.9
QUARTER MILE--13.4@105.2
BRAKING--60-0 102 ft
LATERAL ACCELERATION--1.01 g (avg)
MT FIGURE EIGHT 24.7 @ 0.76 g

Cool. Proves my point. The z is designed around benchmarks, so it looks "good" in magazine tests. The high G numbers are fundamentally flawed due to the poor handling characteristics (limiting understeer). It gives great LA numbers, and poor track times at the limit.


If you use magazine test numbers as anything but a ballpark estimate of performance, you are doing it wrong.

Red__Zed

Methodical, the thing you need to understand is the tire width benefits we see a lot of times. The nismo has to run huge tires (most guys run 305s in front) to really compete with Sti's and Evo's running 275's at most.

Methodical4u

I understand tires and a lot of things come into play when talking about this... however, i'm trying to compare on a stock vs stock basis though. We know the Z has HUGE tires on the car and more contact patch typically will mean more grip. The Z has the tire advantage stock, while the STI's or Evo's etc have the advantage of more torque due to turbocharging with A LOT of boost and in the Evos case computer controlled handling.

Red__Zed

Right, but stock classing is based off of keeping stock rims, and shoving on a huge tire--no one does that. The wrx moves up favorably with more tire, which bumps it to decent b stock times. The nismo puts down similar times to a wrx running 265s while it is running 295+.

Methodical4u

Yes I realize that and trust me, I was quite close to getting a WRX, but it doesn't come with 265's. We're getting away from a stock for stock car again.

I don't have all of the stats for either car. The weight distribution for the Z says 53/47 which seems pretty good... I don't know how good or bad that is... I never cared much. The Z (and i'm talking about the standard or sport model Z) that is labelled a CS car is still stock for stock ahead of the WRX according to the SCCA ratings... but since you yourself have said that your WRX has been ahead of Z's by "1-2 seconds" it would appear that their way of classing cars is flawed and that the WRX should be in at least CS correct?

Now if we want to start talking modding... the WRX is likely going to have an advantage because of the turbo and tuning and such (now getting back on topic) it can get more power out of a tune. The WRX guys themselves have told me that once that car gets to 350-400 whp that the tranny will have to be upgraded or replaced to handle that power... and while some say it's different, other suby guys have told me that's not the case and that the drivetrain is still weak and again... I haven't done the research, but this is just what was told to me and this was on the Subaru forums. Either way, there are more parts for the WRX than the Z... pretty obvious why.

I can only go by my own personal experience... I have seen Evo's on track overtake GT-R's and been close to top of the line Vette's... but this is also pretty highly modded. Then you also have the video of the lamborghini murcielago that was pretty easily overtaken by a FQ-400 Evo... and while those are modded, that's not 400 whp as far as I know that's bhp... yet the Lamborghini has much better power and common sense would tell most people that it doesn't make sense for a 4 door sedan to be able to overtake one of those cars with the power output and such.

AWD is my answer. IMHO if you put the WRX in a RWD platform it wouldn't be near what it is now. It also has the symmetrical system and this (take from Subaru's website) "Side-to-side balance, along with a compact layout and lower centre of gravity help give the vehicle greater stability. What's more, the system instantly reapportions the engine's torque between the front and rear wheels as conditions demand, providing powerful traction for more capable performance on any road."

That's not exactly comparing apples to apples here IMO. You still have a computer controlled car in a stock vs stock situation. Many of us have bought the 370z because it's a drivers car... the driver is responsible for the work and for the stability of the car.
