RX8 vs RX7

[yellowmusicfreak]

RX7 was more of a race car beast, whereas the RX8 is a fancier, diluted, civilized version. And of course, heavier, as all cars tend to get over time...damn "safety" regulations n shit makin our cars fat, oversized, inefficient, boring rolling vaults...don't blame the manufacturers, blame the damn American public, and the NHTSA and IIHS for deciding our cars aren't safe enough for all the stupid drivers...

[guevodeplomo]

rx8 fail hey mazda BRING BACK THE RX7

[ikazuah]

nice race



[FAMAS4me]

RX7 says "see ya!!!"

[isthoed]

blah rotarys are lame. that rx7 "barely" beat the very slow rx8 lol

[Tj1056]

@isthoed dude that rx7 is only 40hp more with the turbo units stock...

[stichy420]

@isthoed blah bmw's are for slow fags

[knackerFacker]

What did you expect, racing against a turbo of any kind?

These videos never seem to stop amaze me..... >_>

[hyperdemension]

rx7 won because its not dick shaped like the rx8 lol

[littleRayRay306]

@hyperdemension lol.

[oilfighter21]

i love the sound of that rx7

[monono954]

i think it's crazy that the rx8 is as fast as it is with all the extra weight and lack of forced induction.

[Gin132456]

@monono954 it doesnt even have a twin turbo either.

[CCAAASSSCCAAAA]

It didn't even look like the 7 was trying at the beginning.

[rotarypsi]

pretty funny out their shifting out at nearly the same time even though the renesis has like 2k more rpms to pull.

[chinhido350z1]

Beautiful car but the even the 300ZX non-turbo from the1980's, that's last century has faster times. Just keeping things in perspective. I eat RX's everyday.

[Sefveron]

comparing the stock series 6 rx7 to the rx8 id have to say this is about right, considering the rx7 has just a little bit more power with a little less weight, of course if it was a series 8 rx7, the gap would be much wider.

[rotarypsi]

didnt pull nearly as hard as I was expecting.

[smallnutjob]

*7 BTW

[smallnutjob]

I will have RX, I will kick Porsche Ass LOL

[intensivemedia]

i dont no why mazda didnt turbo the fuckin rx8 they out there looking ridiculous

[smallnutjob]

Turbo it yourself biatch

[guillaumechauvet]

might as well put the rx7 against a family van. a good race would be a rx7 against sum porsche, which is the cars it was competing with when it came out unlike the rx8 which is a car built to compete with civic si-r's.

[filipinobboy510]

horrible match rx8 is so weak

[JeremyClarksonsArse]

"He'll destroy you". Enough said.  RX-7!!!!

[c93fd3s]

lmao the guy in the 7 wasnt even trying..I can tell by sound he is shifting early and slow..lol nice.

[punkmypickle]

thats some slow shifting in the 7

[flymewithballoOns]

rx7>rx8.

[dayboyy24]

bought my rx8 for 7k with 70k miles :)

[tsiris1980]

i got rx8 but respect to the rx7,one of the cars that left history...

[BigDogRoadSide]

wasp010 are you serious!!??? A Renesis better than a REW are you f..ing serous!!!A 13b REW is one the most potent engine you can build in mazdas lineup.....REALLY??? are you serious!!!????

[wasp010]

Not bad for the RX8. A 4 seater naturally aspirated sedan vs a 2 seater twin turbo coupe.

If I was going to build a killer rotary powered street car it'd be an RX7 shell with a Renesis engine. Its just a stronger engine than the REW. If I was going to make a race car I'd take the 20B, stronger and more powerful than both the REW and Renesis.

[vkotis]

i miss my fd :(

[xUdieToox]

some stats for all the idiots watching:

RX-7

255 bhp sequential twin-turbo

210 tq.

curb weight: ~2800 lbs.

RX-8

238 bhp naturally aspirated

159 tq.

curb weight: ~3000 lbs

go figure why the FD would win.

[DankoFury]

"some stats for all the idiots watching:

RX-7

255( the true bhp its arround 260-270) bhp sequential twin-turbo( or Bi-turbo is easily)

210 tq.

[punisher5556]

RX7 are fking import car, bullshit

[Omen6schecter]

RX-7 kills RX-8 allways.

[Rage71000]

You're Right All the way :D

[DjDime92]

@Omen6schecter rx7 can only develop higher acceleration cos of the weight. luxury and external appearance of rx8 are much bettter. .. all in all i'd rather have rx8

[DjDime92]

and it's more practical for general use.. im just in love with that car lol

[PoLaRIV]

@DjDime92 I disagree, I like the kits for the Rx-7 much more. Much cheaper too :P

[travisloza512]

@Omen6schecter hell yeah

[stabe76]

RX7 RULES

[dmi5151988]

was up man, no chance

[88Pornoallemanne88]

Rx7 is the badass of Street Racing...

[Cordius]

What an educated comment.

[fastcarskickass]

The rx7 is still a badass on the strip but everyone i've talked to who owns the 7 has had persistant engine problems and opted for other Jap performance cars such as the Nissan Z.

[maz13bRx]

only problems i got with the 7 was cooling problems i went through 2 radiators in about 6 months, air seperation tank then water seal seal failure but you will get alot of problems with turning up the boost to much, also going single turbo is a good idea, but over all its as reliable as any car.just a shame they need rebuilding 60-100k miles but i guess thats what being a rotary lover is all about.

[SpideyFan6010]

There is no predetermined Rotary engine life. If you take care of a rotary it will last just as long as a piston engine. Bad maintenance is the reason so many rotaries need early rebuilds.

[DaveDanger]

Yeah that and racing it every day

[Cordius]

Piston engines are just as likely to blow while racing. Only problem is, with a rotary you blow an apex, rebuild and you are good to go. With a piston engine, you throw a rod and need a new everything.

[boostin350z]

@Cordius and with a stock turbo rotary you have you a merry marathon distance of vaccum lines.

[Cordius]

@boostin350z True, but I was talking from a reliability standpoint.

[infectrus]

Everyone that bought a rotary and drove it like a grandpa is the reason why they started having reliability issues and needing rebuilding every 100K miles. Also beating the piss out of it wile its cold is a natural apex seal killer. The rotary needs to be raced every now and then, otherwise it will start to fall apart. Thats my take on it.

[DaveDanger]

Actually thats pretty much right. No better way to say it. Thats why I only drive mine 3 days a week or so. One of those days then I run through it in second or third about a couple times. And yes running through when the car starts right out when its cold is an apex seal killer.

[marzox]

rx7 rules...

[james6speed]

-300lbs +2turbos = drag win. let's put twin turbo's on an 8 and lose 300lbs.

[Jhyred]

haha man.. thats funny .. if they wan'ted to see that then.. they would have to then get factory turbo's.. cuz if the rx7 gets aftermarket the 8 is no were to be found again

[Cordius]

Not true.

[RotaryOrNothing]

that is right baby..rx7s rule...im not to much on the rx8s they are beautiful cars but the rx8s that alot people have are so weak..the 300bhp ones now those things are fuckin beasts..i heard that mazda came out with rx8s that dont have the renises in it..is that true?if so i would rather have the 13b with the normal weight rotars even though i can see how the lightweight rotars help performance

[Rollogic]

Big surprise the FD one. Need to speed up the shifting.

[IceDragon387]

.............no....just....no

[tuor1984]

yeah, what icedragon said.

[rotaryrhythm]

"he'll own you"...is about right...the 8 bogged on the start and didn't rev to 9k, but the result is inevitable. Can't wait to start seeing more 300whp+ rx8's with the turbo kits out now. RX8 with 300whp+ = perfect car, imo.

[abominableaussieman]

i plan on bying an rx8, and it will be sooo tempting to slap a turbo on it, but will it be able to keep up with the high revs, thats wat im wonderin

[rotaryrhythm]

The only turbo kit out that doesn't flow enough in the high revs is the stock greddy kit. But with the greddy delete upgrade from MazdaManiac, it will flow plenty. All others (mazsport, esmiril, etc.) are great. The s/c kits will flow enough also. Just make sure it's tuned properly.

[abominableaussieman]

ah ok, thanks!

[Alysona13]

In yo face bitch...rx7 is best

[Dreffy87]

The driver of the Rx-8 is no way flooring the gas pedal... And is shifting gears long before the right rpm I think.

[yagam1]

aw dun be sad . we noe tat was the least result tat was gonna happen . the 7 could have stretch it longer , i tink its the 7 whos the one not flooring mate , not the 8 . face the fact . LMAOZ

[speedgeek123]

you got owned

Rx-7 4 life...

[megaderk]

BOOYA!! RX-7!

[moksyb]

there is a difference between both car clutches

[xUdieToox]

both are great cars- the twin turboed 3rd gen 7 rocks,(which i have no chance of owning) as does the rx-8 (which i currently own)

[Owashu]

I guess thats way they call it an rx8 insted of a 4 gen rx7 there gust diffrent breeds. but still good in there owen rights.

[wistudd]

ok that rx7 was not stock

[driftalot]

There's nothing like the 3rd gen rx7. I've owned 2 of them before. The rx8 looks nice and handles great, but the engine is underpowered! The interior is a little cheap too (the plastics). They should have made it a twin turbo! The reason of the death of this sports car and the other sports cars in this class was the newfound popularity in suv's. the last 7 really was in a class of it's own. til this day, I have never felt such an agressive suspension on any car like I had on my '93 R1.

[TKDWolf]

The interior of the RX-8 is really great, actually.

[AkinaGod]

Well technically the engine isn't underpowered in the RX8. It just doesn't have a twin turbo set up. The current renesis is, um... I think around 18% more powerful than the RX7 2 rotor. The power in the RX7 came from a perfectioned twin turbo set up that had a small turbo for the low rpm and a large turbo for the higher rpm.

[FallenEmber]

Are you serious, both turbos are Hitachi HT12's and they are the exact same size. And the secondary turbo comes online at ~4,250RPM in parallel with the primary, and this controlled by 9 solenoids and a vacuum layout that usually leaks and is filled with problems. Hardly "perfectioned" if you asked me.

[AkinaGod]

It was prefectioned at its time. Not to mention all stock parts burn out quickly if you race it. The secondary turbo was built to come on like that. It was to maintain engine stability as well as keep a constant state of power. I don't know if you knew this but rotary engines don't have as much torque output as a piston engine.

[FallenEmber]

I only own 3 RX-7s, one of each generation. I've swapped out the twins on my FD twice, once to replace the actual unit and manifold, and then again about a month later to port the wastegate. I've also replaced all 33 feet of vacuum lines with silicone hose so I know a little about how the stupid turbo control system is designed to work.

[thelegendkill3r]

I Want a FD :( no money. hey i have a 90 vert :D (cheap stock)

[futaki20]

*Trying to decide*

Heh, I think now I'd go with the rx-8. I'm not much a racer, but I like watching races.

[05yousufm]

wait until the rx 9 comes out i heaard its a 3.0 v6 twin turbo, 0-60 in 4.2 seconds, now thats gonna be sik.. i saw it in a road show showin concept cars

[777ridebmx777]

...do you know what the rx even stands for? If its not a rotary, its not an rx, end of story.

[KoobYajLis]

The only way to not get embarrassed in an RX-8 is just to drive and look cool guys. I own an RX-8 6SP with navigation and everything. I will be the first to admit that off the line, you're probably going to lose, even to a dodge neon (maybe). RX-8 was meant for looks and touring, not civic type drag racing.

[AkinaGod]

Somewhat correct. If a neon owns you for any reason you need to learn to race. Not trying to insult you just saying in general. However, If you want the RX8 to be good, lighten it by about 500 lbs. Mod the engine with a small turbo (nothing fancy) to get it to about 300 - 320 horses and make the engine appropriately compliment the turbo. Now have fun with the subarus and Evos on track :D

[ryansagmit]

i wouldn't be surprised if a neon owned me. seeing as how SRT-4's could run high 13s quarter mile.

[AkinaGod]

Yeah but if you strapped a turbo to your engine like theirs then, good bye SRT.

[chivertonk]

The RX7 and the RX8 are basically the same, the difference is that the RX7 was built for speed and the RX8 was built for comfort.

[AkinaGod]

Actually the RX7 has a turbo, and the RX8 was not going to come out with one because they were trying to apeal to a more civilized society. Unfortunately for mazda they disapointed the Mazda racing fans and didn't apeal to anyone wanting to spend a pretty penny. Too heavy, engine built like a medium between power and gas milage, inside is WAY messed up with the rear seats. Needed to remove the back seats altogether.

[ryansagmit]

and RX-8 seats in the back are nice and comfortable if you are under 6 feet tall. much more room than a G35. 3000 pounds for a RX-8 is still pretty light even if it is a couple hundred heavier than a RX-7, still 500 lighter than a G35. RX-8s aren't drag cars either, and aren't RX-7s at all, but still pretty damn nice. and one more thing. RX-7s were dual turbos. they were sequential. one smaller for ligh RPM and a bigger one for the second half of the power band for a smooth torque curve.

[AkinaGod]

Yea, I want to have that system for my RX8 when I get mine. Love the RX7s. need to get a new 6 speed tranny though. More power to the wheels. Stock RX8 trannys remove 18% of the power transfer. SUcks. As far as the seats, I couldn't fit in one of those if my knees were in my chest. I am 6 ft tall and the first thought in my head was, "The paper adds are a load of crap."

[TKDWolf]

I'm one inch shorter than you and I fit nicely in the back seats. My dad is one inch taller than you and compared the back seats to our mazda3, just that they were better, and easier to get into/out of.

[bakerzfosho]

mostly the only differences the rx 8 and rx 7

have is that one comes turbo charged and ones not they have the same two rotor rotory engine..

[ryansagmit]

the rotaries in each car are engineered differently. the RX-7 had the 13B-REW, which was 'twin turbo'. they moved the exaust port in the housing of the renesis rotary in the RX-8 to let it 'breath' better. it improved emissions and fuel economy. plus the shape of the rotor changed. they were both 2 rotors though. and 654 CC each each rotor.

[AkinaGod]

That's what I love about the RX8 motor. If you did all the same tweaks to the RX8 motor you would have a faster performing car. I don't know much on the RX7 handeling but I think the RX8 has better handeling capabilities. But yeah, I don't hear too much on the RX7 handeling performance.

[ryansagmit]

"Handling in the FD was regarded as world-class, and it is still regarded as being one of the finest handling and best balanced cars of all time. The continued use of the front-midship engine and drivetrain layout, combined with an 50:50 front-rear weight distribution ratio and low center of gravity made the FD a very competent car at the limits."

you'll believe once you've been in one, haha.

[AkinaGod]

Yea I agree. I haven't been in one but that is exactly what they did with the RX8. I have driven evos, subarus, hondas, acuras, (List goes on ill stop now) and I was VERY impressed with the handling and response of the RX8. IF the 7 is anything like the 8 I will deffinately have to own one down the road of life.

[munturo]

To Apimp1013. the rx7 is wider, lower, stiffer, and much more responsive so the rx8 wouldn't touch the rx7 in the bends, and the lack of power means the rx8 will be left in the dust. Mazda built the rx8 more for comfort then for performance.

If ur in the market for an rx8, don't bother, get the rx7 an with the money u save get a t04 single turbo conversion, much more fun. I got rid of the rx8 after i was beat by a standard civic type r (embarrassing as hell)

[Riles07]

Are the RX-7's readily available in North America? I thought they were imports that you have to have brought over here; like the Supra's or the Skylines...

No?

[hatamakoto]

what?? they stop sale rx7 since 1995 in U.S. you only can buy it used. go ebay. plus you dont need supra to import they use to sale in U.S for long time after stoping its production in 1998. but you do need import skyline, which omost every country need import skyline.

[pkJ4i]

RX-7's were sold in NORTH America and so are The Supras

[Apimp1013]

yea yea the rx-7 won but if u put them two cars on a track wit curves the rx-8 would smoke that rx-7

[TKDWolf]

I'm not as sure about that as you seem to be.

[shmacklepap]

Lol you're retarded

[hatamakoto]

um... no.. Rx7 never lose to rx8 especily on track,

and rx8 couldnt even against Honda S2000

[munturo]

hatamakoto is correct, I have owned both rx7 and rx8 and my wife drives an s2000. don't get me wrong the rx8 is a nice car an comfortable to drive, an i loved the interior but it had the same power as a fridge freezer in the low rev range which meant that compared to the 280bhp (jap) rx7, the 8 felt sluggish., hell, the 8 couldn't keep up with my wife's s2000, an that's her car for back and fore work.. lol

[MarcWilsonPresents]

No, stock 7 is faster then stock 8. Not only that but they're handling is about that same.

[ryansagmit]

true, a RX-7 would kill a RX-8 in speed. but i would still lean towards the RX-7 for handling. it was much lighter, and many praised it for it's really great cornering and really great balance.

[AkinaGod]

That's cool. I think if the RX8 lost all its "I want to be a rich mans car." gadgets and devices and stuck with the "Trying to be a good sports car" it would really probably be about 200 lbs lighter just in the crap that is useless to the ordinary street racer and become, "Alright I am a good successor to the RX7." I bet Mazda would sell more of the cars too considering you would drop around 3k in price just from the simple removal of useless gadgets.

[ryansagmit]

haha, i would consider them both sports cars, but i think the RX-7 was just in another class. the base price of RX-7 was reaching 40,000 US dollars in 1995, the end of it's life in the US. one of the reasons it didn't sell well, ending the sale of RX-7s in the US. it could compete with porshe and supras. now the RX-8 is maybe 26,000 US dollars TODAY. much more affordable. the RX-7 was hardcore performance, the RX-8 is performance, fun, and a nice drive. both really great cars.

[AkinaGod]

Yea I think they messed up in that aspect when trying to sell the RX8. sales were much lower than expected in the US I think it has almost all to do with the fact they put a bunch of crap in a car that just wanted to go fast around corners. I think it was made to be a successor of the RX7 but then they screwed up by shoving a bunch of useless crap in there. Not that some people wouldn't use it.. It deffinately has potential though once you remove all the stuff. which I will be doing...

[TKDWolf]

That's what part of the problem with the RX-7's sales was. Everyone was like "wow, what a pure sports car, I really admire it. Oh but no I wouldn't buy one, no." They're trying to bring the rotary back with a car that does it all. After they get a foothold with the technology again, watch out for the next RX-7 with the new 1.6L rotary. If you don't want gadgets, get the sport MT model /o the moonroof, satnav, etc. It's about 2900lbs.

[AkinaGod]

could you send me a link? I haven't seen or heard too much about the new one except that it will be a 1.6L... Which is what my RX8 is now that I modded it, lol.

[TKDWolf]

They have info in it on Mazda's website, but I think it's a 1.6L with an aluminum housing and direct injection? Not sure, but it's supposed to make around 300HP w/o a turbo and alot more torque than the 1.3L

[AkinaGod]

Hehehehe, very nice to here. *Malicious laugh*

[AkinaGod]

I like both 7's and 8's though. Not playing favorites or anything. RX8 is just what I want right now and is available to me. Plus I just researched the crap out of it, so I know more about the 8 than the 7. Both look way sexy to me though.

[ryansagmit]

RX-7 and the RX-8 are my two favorite cars. haha, but the RX-7 is my top favorite of all time. it's a classic, not truly replaced by the RX-8, but the RX-8 is still a pretty awesome car on it's own. yes, very very sexy. haha.

[AkinaGod]

Agreed.

[tomciu88]

RX-7 has 265HP (with turbo) and RX-8 has 231HP only (without any turbocharger) so these is reason why rx-7 wins

but RX-8 tuned by mazdaspeed has 350HP with turbo so that version can smoked old RX-7

(but I love both cars )

[seff56]

haven't seen any of that

[mazdaholics]

have u seen the turbos on a batty seff56? they tiny! the supra got a hugh turbo factory and a 1jz

[seff56]

so rx7 has a twin turbo?

[CANAS13]

yes!

[forkedroad]

yes, a stock 3rd generation rx7 has twin turbo, its 255 hp w/ 217 tq... too bad they didnt keep the turbo for the rx8.. how sad

[RotaryChild]

Madza wanted a good brand rotary production car so they didn't add a turbo for indurance purpose.

[infectedfall]

rx7 kills
