agreed, I really hate having to add something like an oil cooler.

I can't open that site, but is this for a stock car?

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".

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.

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

Besides, my worry is issues caused by the cooler. A whole ton of people have blown fittings--it happens from time to time.

Blown fittings, as with any aftermarket part depends on the manufacturer and proper installation. I can only remeber one instance on this forum where someone had a blown hose. Hardly means every oil cooler is sure to fail.

Doesn't make it any less legal or effective. I'm not saying you don't have to jump through hoops, nothing with dealerships is ever easy.

Ever jumped through those hoops? You are talking 18+ months before you get your car running again (if you go through the courts). Precedent on MM is very thin too, so it is risky.

No I totally agree...and yes I have jump through those hoops. Not as far as legal proceesings, but very close. Not fun at all and I totally agree with that its a huge undertaking, time consuming endeavor. If anything, some nissan dealerships are more "mod friendly" than say Mitsubishi dealers. I've seen Evo owners red flagged for stuff like aftermarket intakes. I would bet if you had a Nissan dealer install a Nismo oil cooler, they would be more likely to work with you to find some kind of common ground should a problem arise.

This is also a bit off topic to the OP's question.

Yeah, I just wish they offered it as part of some package from the factory so I didn't have to worry about it. Not worth the stress IMO. I bought the car to have something fun with a warranty. I'd still have my s if I wanted to fix my own problems every weekend.

I think everyone on this forum has that request from Nissan. It's not like its an expensive part. I would have thought they would have at least come standard on the Nismo.

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.

Braking-- 60-0 113FT
Lateral Acceleration-- .93g
MT Figure Eight-- 25.5 sec @ 0.73 g (avg)


2011 Nissan 370Z Touring

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.

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.
