Yes, everyone was curious about that also but AAM cleared the air.
Really once you start tuning either car it is nulled out performance wise. The Nismo tune from factory basically is a couple minor tweaks which is paired with the exhaust. One reason why people say if you are going to go crazy modding it might be best to jump on a base/touring with sport and skip the Nismo.

very helpful piece of information:tup:

you guys sound like democrats and republicans trying to change each other's views :)
it's simple really. those who think the nismo is worth it bought a nismo and those who don't think it's worth it, did not buy one.

After thinking a little deeper into this, if i remember correctly the NISMO rims weigh something like 20lbs for both front and back...base and sport packed Z's IIRC weigh something like 23ish front and back....that unsprung weight loss could account for the HP diff too. Rim weight makes a difference on the dyno....hhmmmmm intersting

I've said that before. If people want to heavily mod their cars as in body kits and new rims and so forth, they should get a base/touring. People that bought the nismos love the body and rims not because of the HP increase. No nismo owner in their right mind bought the nismo just for that 18hp increase.

I love the way my car looks over the fangs. I love my rims over the sports package. That is the reason why I bought it and it is the same reason why many others bought the nismo.

hmm, i thought HP was affected as well. I remember a while back a buddy of mine dyno'd his LS1 with chrome corvette rims (heavy) then he took them off and put stockers back on and made a gain of about 15ish...significant

LOL! I'd be willing to give any stock 370 Z a 2 second head start on local road courses. Suspect I would make up time within half a lap.

Dont underestimate suspension, power and handling advantages of the Nismo. I dont think Nismo was building a drag racer my over blown friend.:driving:

But hey its a free country if you want to ruin a stock 370Z, void warranties, etc go for the major aftermarket pimp and blow! I think most educated buyers will see value of the Nismo over buying a Sport model and adding a bunch of cheezy or very expensive aftermarket parts.

But at least have a sense of humor about it!

I cant tell if your joking or not anymore:confused: but here in SA its usually the nismos that are stuck on lots getting discounted for sale vs other models...

+1 for being the dumbest thread ever!

lol, does the OP just realize he told everyone who owns a 370z that their car is slow?? 370z's arent slow cars... you just spent alot of money to make yours faster...

[QUOTE=GZ3;914466][QUOTE=Cell;914451]I always thought less weight on the rims means better torque and not HP. Smaller diameter rims always means more HPWere the two rims the same size? I know in the RSX community when people went from 16" rims to 17", they lost HP. No idea what lighter wheels do for HP wise. I just know losing some weight will always give better performance.

Shamu, I'd love to see what your stock nismo can do against my car. I mean...I understand its a good starting point and great if you're not into modding....but you need a reality check. We could both have stock cars, but if I put on my RE-11's then you'd be in trouble already. Add 150whp, coilovers, lighter wheels and a good alignment and I'm sorry man, but no fancy front bumper or extra seam welding is going to make up for it.

I love the Nismo and wish I had started from it to keep weight down and for the extra chassis rigidity, but don't kid yourself. I know people focus on numbers and don't realize the importance of better balance, etc. However, your car overheats and has brake failures just like mine did when it was stock. It's no track car, its barely better than the sports package 370z...

Depends on what you mean by fast. The z isn't relatively slow in terms of performance cars.

[QUOTE=Cell;914788][QUOTE=GZ3;914466]yeah they were the same size 18 chrome corvette wheels to stockers 18's...intresting

fast in relation to furiousness
