Age-Old Battle! 240Z vs. 280Z

    Recommended Posts

    Hey folks! It's time to open up that wound again! We all know there's a little bit of tension between the 240z guys and the 280z guys (At least I have a little) about the differences in our cars.

    I wanna know why you think each car, 240z or 280z, is better than the other, and your reasoning behind it. No cheapo answers like, "The 240z is better because it's the original." We've heard that one enough, tell me YOUR reasoning behind your argument, even if it's simple.

    I think the 240z is an awesome sports car, and it has its place in history as a car built out of need, but the 280z was ALSO born out of necessity: to stay powerfull in the face of a gas and safety crisis.

    As a result, I think it made it a better car in some ways than the 240z. For example, its frame rails are thicker as is the metal, making it stiffer car in general (heavier as well, yes).

    Not to mention the fuel injection. The 240z had 150hp stock with a 9-to-1 compression ratio. The 280z not only overcame its 8.3-to-1 ratio by gaining enough horses to reach 149 (rated at 170 at the engine) but GAINED 15 LB/FT of torque over the 240z! (check zhome for the specs) I think this is augmented by the lower redline, making the power more accessible.

    This is my view of a couple facts that have been overlooked when considering the 280z compared to the 240z. I LOVE both cars though, so don't worry, I'm not bashing! This thread was partly born out of envy of the 240z's out there!

    I love the 240z because its lighter , not as common and doesn't have the larger bumpers. Besides I like the simple aspect of the 240z , just your basic motor , light car and lots of fun.

    I agree totally. I haven't found my Z yet, but I'd say that chances are better than 90% that it will be a 240.

    According to Zhome, the 240z pulled between .72 and .78g's on the skidpad, while the 280z pulled about .72. that's 6/100ths of a g difference. I guess you're still right, but the gap is not large. That is, if we're talking stock form.

    What about the 260Z? Some people prefer the via media, so to speak.

    Anyway, 240Z for me. Lighter, better looking, simpler, more focussed in terms of its philosophy and THE ORIGINAL! LOL

    I think if my Z gets totalled or stollen or explodes, I'll get a 240z..but for now, I like my 280z. I would like to see a race between an SCCA prepared 240z and 280z. Hmm..better head out to the track next month! hehe.

    There's a lot more to handling than just the skidpad numbers. Lighter car is crisper and more responsive. Skidpad can't tell that.

    Mass and geomerty-240 had lower mass, 280 had better geometry!

    The front suspension has more travel in a 280Z.

    Sway bars were standard on both ends in a 280Z.

    The bumpers kill me on the 280z, but I prefer to work on the fuel injected L28 over a L24 any day. I am young and I know nothing about carburetors, I dont even know if I spelt that correct, so I looked for and found a 75' 280z. It is simple to work on and reliable for the average person. So if this discussion was on the original car, no swaps, I would go for the 280z for the motor.

    Awesome.

    My mistake, this thread has been covered before actually. Sorry for wasting space, hehe.

    It's my understanding that the 280z was a better built car, and feels more solid when compared to a 240z, not to mention less rust, and cheaper.

    I also think it was examined that the the 280z had a slightly better power to weight ratio if you can believe it.

    I think part of the problem was the fact that the suspension wasn't augmented to hold the extra 500-or-so lbs of 280z and the suspension was mostly carried over from the 240z, probably to save production costs, and as a byproduct, Nissan marketed the car as more "luxurious".

    As much as i love the original 240z i would go with the 280z , but remove the bumpers totally =) Ive had the chance to fix both and drive both ( not very far but... hey i can tell the difference) and the 280 had a lot more zip. As for handling thats totally stock and most people out there atleast have modified tires so it will most likely cancel that catagoery out. They are both beautiful fun cars but when it comes down to working, fine tuning, driving, and saftey regulations i would take the 280( once again without the bumpers)

    I have also owned both. I had told myself that I would ignore this thread since it's been done to death but I couldn't ignore the '280 had a lot more zip' comment. Must have been the cars you were driving. I own a 280 and it's in as good running condition as most basically stock ones you will find. But I also owned a 70 and a 72 in the past and as far as 'zip' goes I would take either of my former 240Zs over the 280. As far as ease of operation, however, I'll keep the 280. But, leave the bumpers alone, they are, as I have said before, part of what makes a 280 a 280. If you want a 240, buy a 240. Trying to create that 240 feel with a 280 will only leave you wishing you'd done that in the first place. Peace, out.

    maybe it was just my 240. I drove it before restoration but it was fine tuned. I did the same with my 280 before restoration. Maybe im just remembering wrong. Anyways my 280 isnt totally stock either, has quite a few mods to it so maybe thats wat caused it =)

    Speaking of mods, I thought about the track Z's I've seen in Grassroots Motorsports and at SCCA events, and here's something I've found:

    For a stock comparison, the 240z edges out the 280z because of its lighter weight, and better suited suspension.

    Light modification: 280z. Suspension upgrades really help the 280z overcome it's soft suspension, and compensate for its heavier weight, while intake and exhaust allow the fuel injection L28 to work at its full potential with the stock cam.

    Moderate modification / light race tune: 240z. New camshafts match the L24 well, and when coupled with race-tuned carbs and engine balancing, a 240z becomes very quick.

    Heavy modification / full race tune: 280z. Thicker overall construction makes for a more stable racecar at very high speed and high G application. Better platform for very high horsepower. (just look at the BRE racing history)

    I could be wrong about a bit of this, but it's just an interesting comparison I played around with.

    I put a 240z exhaust on my 280 ( just straight pipes from the manifold back then a nice muffler) to get rid of the catylitic converter because it was a california car. Now since i did this did i get much of a HP increase? I know when you take off the cats ( or cat. in this case) it adds some but i was wondering how much. Sorry for the random response but mods were brought up. Anyways perhaps safety and emission regulations were the reason 240z's beat out the 280'z's totally stock? I think with mild modifications a 280 can become about the same weight as a 240, those damn bumpers have a few pounds on em heh. Ohh yah is it legal to remove them? or do you have to have some means of a bumper on a vehicle in massachusetts.

    That's exactly I have been reluctant to get into this thread. A modified anything should be able to outpreform a stock car. I can strip everything out of my 280 that's not necessary, build the snot out of it and be as fast as a lot of things out there including most 240Zs. And the point would be? We're no longer talking about stock vs. stock and I'm no longer talking about this topic. Once again, peace, out! (this time for real) :ermm:

    I'll be making a "test pipe" for my Z's exhaust when I get it put on. Not legal, but totally acceptable in my opinion, hehe.

    BTW, here's the thread we should have continued:

    240z vs 280z

    Mass and geomerty-240 had lower mass, 280 had better geometry!

    I would like to know why the 280 has more suspension travel than the 240. I know that the rear strut housings are 1" taller on the 280 vs the 240, but I thought the fronts were exactly the same length. I was also under the impression that the stroke was the same on all of the Z struts, front or rear. Same stroke = same amount of travel unless there is something that I'm missing.

    Geometry is slightly different in that the 280 has a higher cg and higher rear roll center as far as I can tell. Above and beyond that I see no major difference in geometry, and I'd prefer the 240's geometry if it was to remain stock.

    Sway bars are easy to install on a 240 or a 280, FWIW.

    The light weight of the 240 is the selling point for me and because, I know I am not supposed to say it, it is the original. The feel of the lighter wieght is awesome. I have done some modifications to the car, but if I did the same suspension work and got the same power to weight ratio in a 280 as my 240 and used the same tires the 240 would win in an autox (autoxing is the reason I drive a Z) due to the weight difference. Lighter weight cars handel better and feel better.
