rx-7 vs supra vs 300zx
 

Im just trying to talk about this for fun so I dont want any flame wars. I personally own a 86.5 supra. My older brother owns a 300zx and Im trying to get my little brother an 86 rx-7. Through my personal experiece I would say the supra is the fastest or most powerful, the 300zx as the most styled, and the rx-7 is the best handleing even though I havent driven one yet. I just wanna hear some opinions of these 80's sports cars. And if anyone else can add to the pros and cons of these cars please add.

Put an 89 TII in that bunch instead of the NA 86.

well to compare them, Ill just remember when my car was NA. Cause the 300zx is NA too. I understand you gotta compare them as all NA's or all turbo's

80s tii > 80s supra turbo ...speed, handling, style you name it :) end of topic
oh and the z doesnt compare to either...heavy, slow, etc. I have driven a turbo z and it wasn't all that fast and didnt handle anywhere near the rx7. I raced a few supras sotck for stock and tii > supra :)

SmogSUX - I understand style is completely an opinion. But you think that stock for stock the TII is faster then the mkiii supra turbo? And for mod to mod you think that the TII is faster? Im not trying to say your wrong. I just know how much potential a supra has and I dont realy know much about the rx-7.

sotck for stock the tii is faster. i dont know about modding though since i raced a stock supra turbo in a stock tii. Again though the Z isn't anywhere near competition level.

yea... I knew that the 300zx was slowest, but they have a nice body style I think. I would have to say that from what I have heard the TII and turbo supra are pretty close stock and the TII might have a slight edge. I just wish the supra was as light as the rx-7.

I've driven a stock MKIII Supra with a 3" exhaust and boost controller as the only mods, and it was slower than my TII was with just an intake..

I remeber the day I smoked a 95 300zx NA in my buddies 88 RX-7 vert. No chance for the 300zx.

my supra is way faster than my turbo II, but then again i have a 2.5 twin turbo in it ;). I love the 7's handling but the supra is alot more comfortable, IMO

well.. now that I know a stock rx-7 is actually faster, lets just say that the rx-7 is a lighter, more aggile car while the supra is a torquey heavyier car. Honestly I think that a race between the 2 would be determined by the driver. honestly I just like the fact that the 3 of these car are under rated as 80s to early 90s cars. people today are so wound up in vtech and awd that its nice to have a older car that is tried and true. I just never realy thought of the rx-7 as a peformance oreintated car. I was wrong and Im very intrested in them

300Z?
Z32 or Z31?
Both are HEAVY.
Z31 is too damn slow.
Z32 NA is too damn slow.
Z32 TT is okay, but it's still heavy.

Supra?
MA70 or JZA70?
Both are heavy.
NA's are too slow.
Turbos are slightly faster but still heavy.

300Z versus Supra is a good comparison.
The FC is NOT in the same category.
Although an FC NA would run comparable drag times, the FC would runs rings around both in the turns with a competent driver.

FC turbo would just outclass both the Z32 and JZA70 even with turbos.

^ spoken like a true rotary owner :)

Is there anybody around CT or Philly area that would like to back up these claims? I only have intake, exhaust and MBC. I would be very intrested to see how a simillarly modified TII would compare to my supra. Just as one car enthusiest to another and as fun.

even if i did live there....my tii is heavily modded now lol....and the near blown turbo is hella tyte..seriously i think my car would run 15s right now

Anyone from either PA or CT would be cool. Id just like to meet up and check out a rx-7.

wait...so you dont have one. think your supra is faster . and post on our forum.

No... I found a 86 NA that I am trying to buy for my little brother. I found this forums to learn about the car because I would be working on it for him. I dont have a rx-7 but I honestly never thought of them as fast cars, I just thought they were a little underpowered. My reason for posting this would be to figure out the diff. between the supra rx-7 and 300zx. When you guys said that the rx-7 is in a different class then the mkiii supra I just kinda wanted to see proof and talk to a person in real life about these car. Im not in any way saying my car is superior, just intrested i guess

we don't lie. rx7 is faster. :) take our words for it.

Obviously there's going to be a little bias depending on who your talking to...

The TRUTH is:

Rx7's > all

fool your car is much is easily a high 13 second car you just need to practice at the track 15's haha you have to be crazy

I've driven both cars the 88 N/A Supra and the 86 Turbo 300zx. to me i think we all know they out TQ a n/a rx7 easy but they felt slow. my rx7 was more responsive took off quicker and can out handle both. but im not a stock rx7

:werd:

/thread

buy that n/a and put a stock s5 turbo on it.... that car will run 12's if done and tuned right ;)

Thats wrong, 89 TII and 90TII are both 6.3 and 14.9... No way in hell is s4 TII faster than an 89 s5 TII.

not with my current turbo :) major loss of power @ 6k and no power @ 6.5k....kinda sucks for a car with most of its power at the upper rpms :bigthumb:

Dude, the FC is like around 500 lbs. lighter than either the Supra or the 300Z.
That should tell you something.

The FC can be made to "dance" around corners.
I've never heard someone mention "dance" and "300Z" or "Supra" in the same sentence. :)

FC NA's should be plentiful in the classifieds.
I'd suggest taking one out for a test drive to see what it can do.

do you know what a jza70 is? all i have to say is, i own both and the supra would smoke the turboII in drag. rx7 has much better handling though, the supra is not a "sports car" its more of a gt car and they are not in the same class. the supra has alot more luxury options compared to a 7....... and its a big brick on wheels..... but the jza70's are still fast. stock for stock a jza70 would smoke a turboII in drag, and the turboII would outhandle a jza70........ IMO

How will a Supra smoke an RX-7 in drag racing? They typically have horrible 60ft times from having to accelerate nearly 2 tons quickly, and spend most of their time spinning tires. Whats the difference between a 300HP Supra and a 700HP Supra? They both run 12s..

same with rx7's... and supras sure aren't faster... can't say that rx7's are a whole lot faster... but rx7 > all in handling... and as far as looks are concerned, well, 80's supras look similar to rx7's. And 80's ZX's are ugly. With a body kit and such, they all look fuckin bad ass.

Socc924: Like others have said the Rx-7 is much lighter. Consider also that the balance is almost a perfect 50/50 front to rear... it's like a 944 except the engine is so light that it doesn't have to put the transmission in the rear.

I raced an 80's turbo Supra in my N/A with just exhaust and a cone filter. Exhaust = header, presilencer, dual ebay fartcannons . He got a slight jump at the start as he hit the gas before I downshifted, but I began to pull on him near the top of 2nd gear - we let off around 65mph, as it was just a friendly thing. He also had a passenger. Still, for him to be boosted, it was quite redeeming for me.

BTW, the "pulling" was very slight - at the beginning I was about at the rear of his door, and by the end I was at his front fender, so it was more even than anything. I can't wait for boost! :D.

A friend of mine has an N/A supra that blew the motor, he plans on rebuilding it and adding boost - I plan on boosting my N/A - we can see how that works out when both cars are on the road.

Okay this thread was kinda asking for trouble from the get go, but here is my take on it. I have worked on them all in both n/a and turbo form. each is different and individually suited differently. the supra is the muscle car of the imports. its heavy and full of power and potential but the wieght and luxuries make it lack luster on a road course. the z's best assest is its heritage. again similiar qualities as the supra and after recently redoing the suspension on a 87 Turbo Z i can say they have the most difficult suspension to work on. (just my opinion after plenty of broken knuckles) the rx7 suffers from a lack of torque in comparison but can carve roads very well do to less weight and a free revving powertrain. All of these vehicles are now almost 20 years old and each one requires some serious book time to be well versed in repairs and maintence and general knowledge. None of them are stupid simple like the hondas of 90 up. but they were all true sports cars, and to each his own. all of these cars have tremendous potential so pick your poison.

see... rx7ridah me and you have the same views of the 3 cars. your whole post descibes it exactly. And to add to the difficult 300zx suspension the wheel bearings are a biatch. I guess I just wanted to raise the awareness of the supra to rx7 owners like the rx7 has become aware to me.

Ive driven both cars, and the MKIII Supra is much < the FC, and I'm not biased based on what I own. I was going to buy either a Porshce 944, FC, MKII Supra, or MR2. I went with the FC since it's much better overall than any of these vehicles..

my friend owns a turbo mkIII with boost controller set at like 12 psi on stock turbo, intake, exhaust.
I own an 87T2 rx7 with S5 motor w/ street port and lots of lightening at 6psi and i smoke my friends supra like nothing.
supras need tons of power to get moving, they just weigh too much to handle well or accelerate fast enough to keep up with the rx7 turbo, but like anythign else they can be modded to make tons of power. Now the mkIIII is a whole different story when they did that car toyota did a good job they made plenty of power and potential to move that 3300 pound car.

MKIVs are the same sort of beast as MKIIIs, they need a ton of modding to be fast at drags, but are highway terrorists..

I see no one likes Mitsu/Chrysler Starquests? Another 80's sports car that has long been forgotten.

Yah, the n/a's in STOCK form are slow as balls.

I hit 14.9 in my n/a with not much work and a little weight reduction. After my rebuild/port as well as some other mods, and without a tune at all, my n/a is now noticeably quicker that my rx8 base (14.5 stock) and has a much better torque curve (it feels like). I'm guessing my n/a is low 14's since the rx8 is 14.5 stock, and I'll find out this summer. It wasn't very hard to get it there, TII's are much easier, and high compression turbo'd N/A's are even easier!

Up until a certain point, when the lower compression Turbo engine is a huge plus.

And what point might that be? With proper management, tuning, and cooling the high compression turbo will go further than the lower compression turbo. Money talks :)

I was reading about some guy in a road race class a while ago. Peripheral ported, renesis rotors, 20b, turbo heh. With enough money you can go crazy like that guy :D

sorry to bust your bubble guys but, i own both, 88 turboII and a 87 toyota supra with a 1jz, for those that don't know what that is, its a 2.5 twinturbo only avalible in japan, thats the difference between a jza70 and ma70, and stock for stock i can garantee that the supra will beat it in drag......... and don't forget, i OWN both cars, but i do admit, the rx7 loves the corners....... and i love driving it thru the corners......

I don't think anyone was talking about the engine you have that is "only available in japan." I'm pretty sure they were talking about stock available in this country.

i dont even think the 1jz came in the mark 3 supra in japan, it came in some other toyota car over there, i know its a popular swap, but is that even a supra motor? thats like me saying yeah my LS1 rx7 is much faster.....

The TII is a powerful car. I think even mod for mod it has no problem running with a supra in a drag. yeah it wont make as much hp on a dyno but it doesnt have to because of the lower weight. So yes stock they dont make sick amounts of power but they are just exhaust, intake, tid, mbc away from 10 psi and low 13 sec slips. Im sure a supra is similar. As far as stying goes mk III supras and fcs look similar. So similar that I have had my car confused for one on a few occasions since its debadged. Also the conquest/starion was a sweet car too. Right in the same class, as a matter of fact I would put it right behind the Fc and then the supra and then the z.

Isn't the 240sx a more worthwile contender than the early 300zxs? Especially NA.

i have yet to drive my 7, but i know all of those cars are better than my 88 trans am i just sold :)

a jza70 is a supra, that is powered by a 1jz............ and it did come in other cars such as the soarer.......... but it was availble for supras..... 90-92...........

they mentioned jza70......... thats a twin turbo third gen supra............ sorry but i was just going with what they said..................

i think a done up 1jzgte twin turbo setup is great, the 7m series motors was a dying breed. Thats why in japan that went with the jza70. Comparing that is like having a 13b two rotor and a 20b three rotor. So saying anything about the jza70 is comparing apples and oranges.

Second off, I got rid of my mk3 n/a 1991 for my 1988 rx7 turbo, and never been happier with the performance, styling, and handling. To me, this is what makes a sports car a sports car.

Ive been in a 1990 s5 n/a rx7 and it had everything done to it suspension wise. I swear we went around 90 degree turns at 75mph and didnt even feel it. I think the conquest's are the bomb, they have great tourqe and hp ratio, and handle great. still i wouldnt trade the rx7 for anything else. well.... an fd. :)
