i am a big z fan and although they are my favorite cars (the whole line of em) i dont know too much about the earlier models...i love the look and with them being so light weight i see them having really good performance potential...i want a turbo car really badly so im more interested in the 280zx turbos...what i want to know is how well would one hang with my 91' 300zx NA...how much Hp do they have stock and what they run in 1/4 mile, id also like to know what your guys's cars do 1/4 and what upgrades you have...oh yeah also how do they handle?
thanks a bunch hopefully ill get a nice 280 soon

240-280s are great cars, handle well for '70s era cars, and your 300 would kick the butts of almost every stock one made. Probably the turbo ZX too, although it might take a little longer. There are tons of books out there about Z cars with all kinds of specs about power, speed, 1/4 mile times, upgrades, etc. They and the many other Z sites (see links) are probably a better source of meaningful information than asking such a broad question here on the forum. Also try the archives on this site. Good luck, and let us know what you end up with.

Well my friend, I own a 1982 280zx Turbo. And although it doesn't run correctly yet ( still waiting on a part to seal my turbo to stop that air from leakin ) from the research i've done, i found a website with the STOCK 0 - 60, 1/4 mile times of all Nissan cars ( i lost the link and can't find it again oh well ) and the 280zx Turbo was the fastest Z car made in the 0 - 60 and 1/4 mile until the 300zx TT came out. Thats the factory spec.


Hope this helps you in deciding to get into a REAL Z-car, the inlines =)

P.S. you need any help with your car anyone on this site will help, plus e-mail me i check it everyday and i'll write yah back with whatever yah need ( if i dont know it i know someone who does ) so buy an older Z...and enjoy it.

The 280Zs---135hp. 280ZTs---185hp.

I will have a 83ZXT Ttop with 140K that I am almost done reconditioning [ rust fixed, repainted, new carpet, etc. ] for $3000 it is black & very nice looking.

I drove a 86 ZX about 6 mo. back, the 83ZXT seems quicker.

I live near Fort Dodge Iowa I hope I am close enough for you to look at. It is a sharp looking car, purty dam quick, at what I think a fair price.

I also have a 78Z that gust turned 100K for $2500 almost as nice looking & almost as quick [ a little bubble rust in paint around rear wheels ]

the older, the better

Believe it or not, the old zed cars actually got slower as time went on - a stock 1969 240z would beat a stock 280z (non turbo). Even though the engines were getting bigger, the cars were getting heavier, longer, and had more emission controls. All this changed when the turbo 280zx was bought in. Almost all z's (form my country, anyway) have had their emmision control systems removed by their owners, so this helps beat that problem.

Of course, a popular conversion is to take one of the bigger engines and put it into one of the earlier, lighter cars. Still, your not going to match the 300zx, as I foolishly tried to when I first got my 260z. The nice thing is, though, that if the guy in the 300zx knows z history, hes going to slow down and stare at yours with a tear in his eye. I quite often have 300zx's 'escorting' me on the motorway.

Re: the older, the better

Ok, here's my read on this. With all the mods available for all the different Z cars, it's not really that important which Z was fastest off the production line. Any Z out there can be a fast car, it's all in what's been done to it.

On the other hand, driving a 280zx will never FEEL the same as driving a 240. When I got married I had a '71 240 and my wife had a ZX (I forget what year). The 240 felt like a fine handling engine with two seats strapped to it, loud road noise and rear-end whine, stiff clutch, and lots of raw unrefined power. In comparison the ZX was much quieter, much softer feel with the clutch, much softer suspension, basically all the comfort features. They were just about dead even 0-60, but the ZX just couldn't keep up on the corners.

So it's all in what you like. Personally I love the unrefined tin box feel of the early Z's the best. BTW, my daily driver is a '89 535i but I wish it was a '72 2002...

Re: the older, the better

Tin bucket is right...seat of the pants is another. Those newer ZXs (280/300) and the second gen 300s are great cruising cars, but IMHO, they're not sports cars. The Essential Datsun Z book has the following 0-60 times for the various cars:

240 - 8.0 sec
260 - 8.2
280 - 9.4
280ZX - 9.2
280ZXT - 7.4

Of course, after you throw in a turbo or 3.0/3.1L engine in a 240 you can do that in 6.2. My 3.0L 240 does but at speeds over 100mph I find it a very light car indeed.

Who needs a stinkin' Turbo...hehe

Light makes might.

The early 240's are killer.

Here's a short list of mods and times I have acheived in my stock weight daily driver 1971 240Z.



Stock 9:1 CR 2.4L with E31 head and 262/272 Crane cam,stock Dual SU's and headers with 2 1/2 inch exhaust, 3.9 rearend, early 5 speed.

9.45 @ 73 mph in 1/8 mile
14.7 @ 91 mph in the 1/4 mile




10.6:1 CR 2.4L with .070" shaved N42 head and 272/282 Crane cam and same setup as above.

8.74 @ 79 mph in the 1/8 mile
13.6 @ 99 mph in the 1/4 mile




9.6:1 CR 2.8L with .070" shaved N42 head and identical setup as above.

8.56 @ 81 mph in 1/8 mile
13.4 @ 101 mph in 1/4 mile



10.7:1 CR 2.9L stroker with above items and slicks and late model 5 speed.

8.20 @ 83.3 mph in 1/4 mile
12.93 @ 104 mph in 1/4 mile



10.7:1 CR 2.9L stroker with Big Bore SU's

8.22 @ 84 mph in 1/8 mile
12.88 @ 105.8 mph in 1/4 mile


11.6:1 CR 2.9L stroker

????? Spring 2002.


The early 240's are the most versatile Z cars and are not subject to emissions inspections in most states.

As far as handling goes, due to their light weight they are also the best Z car for tight autocross courses when setup properly.

wait wait hang on

Wasnt there a jump in hp for the 77 and 78 280s?/??? I know there was a downward trend and i have seen all kinds of numbers, but i have some nissan north america literature that says that the 75-76 zs had 149hp and in 77 the horsepower was 170. Thats what the tag under the hood of my 78 says also. I dont know, are these ficticious made up by the factory or what? I cant really find any stock dyno results on the internet anywhere. Either way , just my .02.

Norm?

Norm, did you ever try your 2.9 stroker with the early 5 speed? I didn't see any numbers posted for this combination. Just curious!

Re: Norm?

Well sort of.
I ran it with a modified late model tranny. In other words it had the 79 input shaft and countershaft gear mounted on the 82 tranny which gave even lower ratios than the early 5 speed.
However, due to a lack of race slicks I was not able to make a better run than I had with the regular tranny.
The car would spin fiercely going into 2nd and 3rd gear with street tires.
