Supra mk3 vs 300zx
|
Mon, 09 February 2004 10:27
|

Hey everyone!
I know this is blasphemous (I'll whip myself with nettles later) but can anyone advise me if its worth considering an '89 Nissan 300zx, over an '89 Supra? Power to weight is much in favour of the Nissan, but ofcourse the Supra is, to my eyes, a beautiful beast. I own an '86 mk3 non turbo, which I find a lot sluggish. The non turbo Nissan should be quicker, and doesn't look to shabby. I could go 7MGTE, but ofcourse the 300zx has the twin turbo option. Help!

300zx also had shocking overheating problems, and constantly break down due to design flaws. Prone to a lot more problems than ma70s are.
If you're not happy with your performance, and like your car, either turbo your 7mge, or buy a 7mgte motor to transplant it!
My opinion...sorta supra biased

300ZX has a dog of a reputation. And don't forget the 1JZGTE option - if your budget can stretch that little bit further.
MHO - and also slightly biased

Haha, its funny you pick two of the cars from each marque that had the biggest reputation for blowing head gaskets.
Personally I'd prefer the Supra, the weight difference is probably not a lot, they both have similar suspension setups, although the braking of the 300ZX might be a little better.
As for power, I'd say lineball between the NA cars, although the twin-turbo 300ZX is obviously going to have the balls in a straight line.

As much as I'd love to stick up for the Supra, they both weigh around the same (if not with the 300ZX slightly lighter) and the VG30DETT has more power, how could the Supra be faster in a straight line?

I'd love to see you against a decent driver in a twin-turbo 300ZX. Just been checking specs and they weigh almost idential yet have more power. They are stock faster than an MA70, you must've been racing NA models...

This is possibly, barring our Mirage-owning friend, the least educated thing I have read all day. Have you heard of power delivery, torque, gearing, and traction?
I have no idea which is faster in standard trim (and really amongst this group of people it's a bit of a moot point anyway), but come on!
And back tot he topic at hand - I'd take the Supra any day of the week. The 300ZX's don't GENERALLY seem to have been as well kept, and also suffer reliability problems almost as common as the Supra - but yet they can look damn horn with the right set of wheels and are easily set into the 13's.
The Supra just has a lot more heritage, class and a far better upgrade path (eg. buy a poo 7m one, throw it in the bin, buy a 1jz crossmember and bolt in a 2jz).

That is to a point correct, but I'm trying to get across to the people who think Supra is god that the Z, stock, IS faster in a straight line. I understand what you're saying, but I was trying to simpify it down to the people who kept putting down the 300ZX.
I said originally that I'd prefer a Supra, and a lot of it would come down the fact that while the 300ZX has a lot of problems due to its packaging, the reliability issues of the 7M can be seen to quite easily if gotten to early.

Now who's talking out their arse? As much as I'd love to agree with you, barring the 2000GT, the Z car lineage has a lot more heritage than I could accord to the Supra...as for class and upgrade path...there are no arguments there at all.
I'm not looking for an argument, just more trying to put facts straight.

And how many 1JZ-powered cars have you driven? How many have you owned?
There are many people who have upgraded their 7M's to 1JZ's, and I've yet to come across anyone who was unhappy they did it. Worth thinking about before you get too excited about 7M's.

This is a very interesting comparison.
Especially when you consider the turbo models. Having driving both and owning a mk3 1JZ Supra I would say it would be purely personal preference which would dictate which car you choose. As they are both VERY evenly matched on a stock platform.
However, when the modding begins, in my opinion the supra takes the lead in leaps and bounds. Have you ever seen the engine bay of a 300 with a VG30DETT squeezed in there ? More to the point, how many substantially modified ones are there ? A few maybe, but if you take both cars, mod them to the nth degree - which one is cheaper. The supra has a cheaper updgrade path, arguably a stronger engine, and quite possibly is a tad quicker than the Zed.
On the flip side however, if you start comparing a 7M-GE, or GTE, well ... apples and oranges guys, they are a totally different fruit. While the 7M-GTE might come close it will never truly compete on an even playing field with the VG30DETT - it's just a step down in terms of power output and engine endurance (?).
In terms of N/A performance, I couldn't rightly say. Test drive a few and find out which car does it for you!

Thats true but I meant nth degree as in to a half-realistic point.

having worked on alot of 300zx turbos and non turbos and also alot of supras of all varietys i would say on the basis of chasis and hanling desighn they are fairly even maybe slightly in favour of ther 300zx personally i have never been impressed with 300zx engines from a performance or reliability viewpointin non modified form they are certainly faster than 7mgte supra but as soon as you aplie even minor mods eg exhaust airfilter the supra seems to become alot beta. really the 7m is alot stronger and reliable 4 high pwr than vg30dett will eva b have seen allkinds of failiers on these engine of all components I think it is due 2 poor oil flow desighns and high temperatures cooking components and insuficient oil cooling my 2cents personally I think the 1j/2j engines are mutch beta than 7m but 7ms still capable of gd things wen set up right

I was more giving my personal feelings with that statement - perhaps heritage may not have been the ideal word - but it is a statement with which many of the Toyota A-chassis owners/lovers (perhaps including yourself) may agree witht he below paragraph in mind.
Both the Nissan Z-cars and the Toyota A-cars started around 1970, give or take a year or so for international releases... and both marques have enjoyed a basically uninterrupted production life of around 30-35 years, so to say that they do not have at least an equal heritage is bollocks.
Oh, and I said nothing about you talking out of your arse, but now that oyu mention it...

Don't let us stop you - by all means you have the right to take the wrong path with engine choice (again)
And besides, you're not comparing apples with apples. To rebuild a 7M *properly* to the standard of a 1JZGTE will cost up around $2,500 to $3,000 - for which money you could have high-flowed the turbos on the 1JZ and had a base engine capable of 400hp.
You also skirt around the inherent problem with the 7MGTE CT26 turbocharger in your comment.
Don't get me wrong, I think the 7MGTE is a great engine when rebuilt - but there are much better options for less money. MUCH better options.
I have had experience with both engines, and let's just say I won't be going with a 7MGTE any time soon unless I suddenly find myself with heaps of money to spend getting the result I could have from another engine for a better price.

I would take the supra for sure. Its a much more common performance
option with cheaper upgrades. good luck working on a 300zx, they are so packed in.
With a 1jz or 2jz its so easy to add exhaust.. bigger fmic and boost controller and get 180rwkw.. and more for a 2jz

Just to jump in, straight of the bat supra, never driven a 300zx so take it with a grain of salt. From what i've heard/know, 300zx's are hard as F&%$ to work on cos of the cramped bay, and lets face it its not a well documented engine upgrade, alot of 300zx's swap cars or engines for the big HP. i do have one here in a zoom with 350kw'ish (i can check later) but th guy has spent mega $$$ for that from a tunning joint in adielade (JPC?). they said the engine had to come out to do what they did (new turbo +mani +cams and internals) just because of the cramped bay. the supra on the other hand could take a V10!
on the quote about the 7mgte to proper spec being a waste, the JZA'a are about 2k more expensive, for that u can AT LEAST get new gasket and retorque the head (72 pound yes?)! i'd reckon MHG ARP Studs and an air filter. then the MA70 and the JZA70 would be alot closer,perhaps note evan. But the 7m does take well to extra breathing, tho the 7m does rev slower. for me? i JZA70, simply cos the car was there and right for me, i origanaly started looking for a TurboA.
i think if your serious on buying one, the choice comes down to whats there. Although for a project car? MA70 with a 2JZ. nuf from me.

300z is not fun to work on
the turbos are even less accessable than the 1jz in my mk2
to change a headlight bulb, it took nearly a full half hour (although if you have an annorexic girlfriend, she could probably do it quicker for you)
and 7m vs 1jz... it's been all argued before. there was a reason toyota made the 1jz to take over from the 7m

personally i find the Z more attractive... something about a wide low car really does it for me 
my uncle has one and he hasnt had any issues with it, but then again this is the guy who has an immaculate 260Z and a hotted up K series corolla *shrug*

Thanks for all the great advice, everyone. I didn't want to mod either car much, I just want the performance to match the looks. And to stop pretending I'm too cool to drag the Suzuki Swifts at lights! I don't know if I'd get better fuel economy with the 300zx, my 7MGE averages about 19 mpg. But funnily enough both the Turbo and non-turbo 300zx is about $700 cheaper a year for comprehensive insurance, than the Turbo Supra. I dont like to penny pinch, but thats a fair chunk per year. I was wondering if the overheating and cooking of engine components in the 300zx would be due to the turbo's, and whether the non-turbo's would have this problem? Half of me wants to keep the Supra, just because of this excellent web site, and the way everyone helps each other out. The arguments are always interesting and productive, and underlying it all is a great feeling of comradeship. Thanks again, guys.

Yes. when you do have problems with the supra, at least we will be here to give advice, console you when you cant afford it or find parts, tell you what you should do to stop it happening again or even just tell tou you need more cubic inches.
Where would you find all this for a nissan?

Regarding some of the posts in this thread and others, are you sure?
And Wastegate (go the 1j warrior!!)... you should know Allan is just yanking the chain of all 1jz owners (as he always does, because he's secretly jealous of our factory metal headgaskets and better intake manifolds).

re the 300zx owners club: apparently most of them are relatively useless - most 300zx owners being rich old men who pay to have problems fixed. My friend used to have one - full twin 3" exhaust system and pod filter as only mods, and even after a tune up it was an absolute pig on the fuel. Dont get me wrong, I love they way they look, and they do go hard, and if not for this website and ease of modding, I'd probably go the fairlady.

The 300zx's had melting problems because the engine bay was stuffed so full with all bits and pieces! Sure, they werent exactly a cool-running engine, and that didnt help things.
7mgte's problems can be fixed with relative ease. Dont get me started on a 300zx...IMO the single turbo version was a better motor, but as i said "IMO'.

Umm 300zx
Funny thing is I know no one who has blowen a head gasket on a z32 other than those who have had coolent pipes fail.
As for 300 owners being fat older guys who pay for every thing to be done.... so ? Go buy a conzult and go for broke on a Z. If you want to tinker buy a z31, or a mechano set.
That said I do alot of my own work on cars, just not the zx.
Now if you want to talk 95+ supras hell yeah get one of those, but before that? ick.
Personally if you want a sports car get an aw11sc.
Oh and heritage? WTF? The supra has a heritage before the fast and the furious? Yes I know they are good cars but please.
the 240zx has a heritage, the rx7, celica gt4 also, but the supra? please.
The 300zx will cost alot more to keep on the road. You must run high octane gas. Parts are not as cheap as the toyota will be. you will get about 9 km per litre of gas ( sorry thats the way I get my figures ). you will get 15.5 s quarters in a standard na auto swb and approx 7.3-.6 ( dont have the corvet figures from the runs we did ) seconds to 98.whatever km/h ( 60 mile ) - again swb na auto.
Stock the na's make 220 ish on good gas in manual trim and 210 in auto. Add pod filter and free flow exhaust ( with an ecu reset remember ) and that'll rise to 225 -230 on good gas. Run crap fuel and you'll get 195-200 and blown head gaskets and low compression.
Want to know more, pm me. also try www.twinturbo.net
Oh and I've watched an NA auto z32 run a 13.0 at meremere in one ladies hands on a 800 dollar nos kit. 8 times in the 13.0-13.4 bracket, then she ran out of nos and went home, in the same car.

Sometimes off line is the best place to discuss some stuff.
exxy? easy? or something else?
if easy then yes 300zx tt's are more common as they are a newer car so fewer have been rusted/ written off. Unfortunately they are still in the cheap enough to be thrashed by idiots, but not rare enough to be cared for by enthusiasts ( the supra would be rare enough by now ). RX3's went through this patten and most classic ( potential ) cars will too. The problem for the late 80's supra is that the earlier cars were so good ( for their time ) and the later cars are too. Much like the z31 300zx they are a bit - eh.
The z32 and z33 are a return to form for the Z cars so they look better for it.

yeah sorry, I exxy = expensive, should speak english huh?
'cause when my brother was looking at these two we found Turbo Supras in good nic seemed quite a bit cheaper than the Turbo 300zxs..
we also considered the upgrade path issue.. but the intial price difference kinda made him think the supra too... though we are kinda a toyota family here if you know what I mean...

Oh ok.
Here a turbo supra ( series 3 ) would be 3-4k
A good TT 300zx 6-12k so I guess....
A 95+ supra (series 5 ??? or 4 ) is 16k+
remember I live in New Zealand so...
I actually came to this forum looking for aw11 advise, but I seem to have been side tracked. I had a supra for a few days but took it back and bought my 300zx instead.

Has anyone actually driven a 300zx? Got one?
People say - 'they are a F!@K to work on' etc etc... yes that they may be but damn they are a good car.
I've got an NA version swb and its been brilliant. Got a full exhaust system on it (haven't heard anything like it on the road... v nice!) pod filter and a few other little mods and she goes. Not great on the fuel but no heavy 3 litre car really is.
But the thing is i've never had problems with it. No overheating no nothing - if you know what your doing then overheating problems can be fixed quite simply on the tt model.
try www.aus300zx.com for things for nissans. Quite a comprehensive site. helped me out like this site has for my toyota many a time.
sometimes people have to 'know' facts before posting on here instead of just reading about them or hearing about them. Coz you can make a dick of yourself pretty easy!
my two cents

To everyone else, you will notice that those 300zx's are fairly low kms compared to the Supras listed.
It also depends on where you shop.
Here in Queensland it's a different story.
Example 1
NISSAN 1990 300ZX V6 - LOW KMS!
light silver, auto, air con, power steer, CD player, leather interior, electric seats, cruise control, immobiliser, Fully serviced And very well maintained, Will trade. SMS Me Options
-$12500 Mooloolaba
NISSAN 300ZX 1989 MODEL
New shape, red, V6 twin turbo, auto, 110,000 klms, 2 seater, electric windows & mirrors, cruise control, climate control, CD player, immobiliser, cent lock, reg'd, VGC SMS Me Options
-$13500 neg Shailer Park
NISSAN 300ZX 1991, black, 4 seater, targo roof, non turbo, auto, alarm and immobiliser, climate control, stereo, sports exhaust -$11500 ONO Duranbah
NISSAN 300ZX 1991, red, auto, twin turbo, climate control, power windows/mirrors, bomex kit, 2 seater, auto, spoiler, leather interior, all factory options, -$11000 Southport
Granted there are some ones in the 20k range but they are all Manuals 94+ years with low kms.
That JZA70 you posted up is nice. Pity it's in WA where most JZA70's were imported to.

you have an off line reply.
you would be suprised at the number of people who run 91 octane in type r's and other "high" performance cars ( wrx's 300zx's, gtr/gtst ) because no-one told them not too.
|
I would call it 'name dropping' rather than a reply
As for octane ratings, the majority of late model cars have ECUs clever enough to retard timing/tune following knock. As a result performance is normally hampered (admittedly on atmo cars this is not generally noticeable because they're a bit tardy to begin with), and even if not the longevity of motors in this situation has to be brought into question.
Nothing hurts me more than hearing a dead standard car drive up the road at a reasonable load point and hearing the death rattle. While driving style and general tune are the major factors, premium petrol would increase the resistance that little bit.

Ok my opinion on all this. I myself own a 1JZ supra but anyway here we go. I personally think the 300zx's do look better out of the box. Out of the box for outright power against a 1JZGTE and a VG30DETT will be very similar, but this is against the 7MGTE so I would have to give it to the zed there. Sure you could bring a 7M up to the point of a zed but you can make almost any car go fast. Did you even want to do mods to it? I think you will be happy with either car, both cars are top cars in their own aspects. But hey isnt this all up to you?

Yup they do, so why do my 99 sti's cook number 4? or vtec type r's burn valves and break stem springs?
Easy there are limits and these imported cars are tuned from the factory for a higher octane fuel than we run here or you get there. Will will note that the type r and alot of the other hot factory na's are listed with less power than the JDM cars for this exact reason.
anyway, are we talking na or tt here? With a chip intake exhaust and boost jets a tt 300 on auto spec turbos will make 178kw at the rear wheels ( with an auto box ) on Robin's dyno at Torque perfomance, a manual car made 199kw with the same setup. Stock cars were 120-125 kw.
P.S. as an interesting side note, try comparing cars on fuel use to horse power. Makes rotories look very silly and Yank v8's look pretty good...... I can't believe I said that.

Actually a well-tuned rotary isn't that bad on fuel, provided you don't floor it everywhere of course. The problem is most people who modify them use enormous Weber carbs or poorly-tuned Microtechs, so it's no surprise they use fuel by the boatload. If you look at the fuel consumption of a late-model RX7 it's actually pretty similar to Supra's and GTR's of the same age.
