RX8 vs Evo7

Ok I don't know if you guys are as fanatical as the Evo7 forum readers, but I was comparing between the two because I might be getting a new car at the end of this year.

So basically going to the cars:

RX8: 1.3liter NA - 250hp, 90% coming around ~3200-3300rpm (according to Road&Track April 2002)
0-60 in 6secs
16" wheels normal (18" optional)
FR drive


Evo VII: 2liter turbo - 260-270hp (US version) around 3500+rpm
0-60 in 5secs
17" wheels normal (18" optional)
4WD
standard ACD & AYC
17/16 Brembo brakes
Recaro seats


Also, please list upgradabilities available for the RX8's NA engine. I know the Evo7 has lots of upgradable components for it's engine and turbo and intercooler, but I don't know if RX8 will be able to reach 350hp using the same engine and just upgrading some components. Any information is helpful on this topic. Thanks a lot!

Rotary Engines are known for making tons of power with few modifications. Also rotary engines like to be driven so don't be afraid of dgetting in on it. BTW, the RENESIS is NA while the EVO7 is turbocharged. 250 N/A horses BEFORE turbo charging is a lot. Just imagine what it would put out turbocharged!!!

i think the AWD in the evo 7 will put it over the top. nothing tops AWD. well for amateur drivers atleast.

Evo 7's going to hand the RX8 it's ass...it really has no chance...supposedly the Evo 7's going to run the 60 in 4.8 seconds...can we say...BOOOOOOOOOSSSSSSSSSSTTTTTTTTT!

:bandit:

4.8? try 4.3 in the new road and track.

r u sure that the new rx8 is a NA car????

isn't it a rotary engine car??? the same as its predecesser RX7???
its a big difference btween a rotary engine compared to NA as rotary has no any cylinder...........

The RX8 is NA for sure...creating 250HP at like 9000 RPM's...the guys at Mazda thought that the HP was alot for an NA car and are deciding to leave it NA for now since it is a good engine...they say.

rotary engines can be both NA or turboed , and yes they actually have cylinders... the RX7s and RX8 have 2 cyliners and the racing 787B and the cosmo or something (only avaliable in japan some years ago) had 3 rotor engines... The RX8 is Naturally aspirated... it already makes a lot of HP just wait till they turbo it... I think that the "gentelman's agreement" of power limit on cars produced in japan is about to be broken... nissan already claims they'll officially say 400 or more HP for the new GTRs , honda has a lot of HP in the new NSX while they say it's 276 anyway , when mazda puts a turbo to this RX8 engine they'll have problems with that too..

i do agree with u.... i have cum across a few turbocharged NA civic in malaysia... 260bhp!!! its a lot compared to its original spec of only 150~170bhp(EK9)...........

i remember 2 years ago a motorsport exibhition in singapore exibit a record breaking civic EK9 from japan of 430bhp!!!

cool.... juz wondering how they did it to a NA engine............

turbocharged NA civics? Huh?

turbocharged NA civics? Huh?

of course, what, never heard of naturally aspirated forced induction?:bloated:

True te Evo7 might be faster but how much cooler it is to drift Fr than AWD??

Exactly, lots cooler. J/K Personally I wouldn't mind having both. One for dirt and one for the road!!

Oh, that explains it... :rolleyes: ;)

I think the reason that the RX8 is rated higher in horse power while being naturally aspirated is becuase unlike the Evo 7... or any other 4, 6, or 8 cylinder vehicle... it's a rotary engine. Unlike the others, a rotary engine has about 6 moving parts... where as the others can have upwards of 90!!

So you end up transferring a lot more of the horse power created by the engine to the wheels.

I know my old '86 RX7 was a beast of a car. Naturally aspirated, well tuned, had the rotors polished and the cylinder honed out, put an intake and exhaust on it. I was pushing upwards of 170 hp. I miss that car. :(

Now I've got my Mirage... and, depending on my deployment status, I'm planning on fixing it up. Though I still haven't gotten an answer to my posting on the Mirage board....

Most probably the evo will spank the rx8 from a dead start but i bet the rx8 has awesome top end like the rx7 while the evo will have weak top like the wrx.

Maybe i am missing something here..but how can a 1.3L engine have more power than a 2.0? Second, isnt it a bitch to find parts if the rotary engine breaks down? Third, is the RX8 going to have the same engine as the RX7?

the RX-8 with turbo :D

Because the 1.3 is a rotary engine wich works a different way. You might be right about parts. No it will be a different engine than the one from the RX7 same Hp but it will be NA.

Evo7!:bandit: :smoka: :smoker2: :ylsuper

they r both awsome but i like the RX8 better cus of the looks

Evo 7 all the way. You know how fast turbo eclipses are (high 11's with stock internals), the Evo's gonna be much better than that. With the its AWD system, good luck on beating it on the street. With the same basic 4G63T engine as the Eclipse, the aftermarket is here before the car is. And for those worried about the top-end, stock gearing it will probably redline out at 135-145mph: T.R.E. = Team Rip Engineering. They build beefed up trannys for Eclipses (Taller 1st and 2nd gears, double synchroed gears, reinforced with stronger parts throughout) and they offer a 25% taller 5th gear. That would push max speed to around 175mph if you had enough boost, not very hard for a 4G63T.

Evo 7 all the way, But some of your figures on the Evo VII's speed are exaggerted. The Euro Spec Evo VII doesnt even hit 0-60 in 4.3 seconds so how can a tuned-down American Spec Evo VII do it? On all the web pages I have seen the Euro Evo VII hit 0-60 in 4.7-5.3 seconds so take a few tenths off for the American Evo VII. :aug2:

hey guys
u forgot that the evo7 doesnt have to be working its tyres on a 50:50
ratio, it depends on what ur driving on and the way u want ur car to handle.
and the other thing is ofcourse u will get problems even though i wouldnt consider it to be a problem just a disadvantage with the low end
and high end(never heard of a high end problem).
if i had the cash i would go for the BMW M3 then there would be no problems at all(darn good car to go out and race at the same time).
in the end i would go for the evo7 WHY?
coz i sat in 1...... its so darn fast, always try the car and dont look at specs alot it can fool u;)


btw dont make fun of the evo7 i might be getting 1 hehe:flipa:

btw u can cry all u want coz where i come from the evo7 has 320bhp
now thats what u call power:D



and for the post above mine u r so lucky to get an M3, all i have to say is respect that car when u get it(a moment of silence with background music)

well my car is very quick with the boost tuned to 8 pounds but the rx-8 most probably will come with the twin turbos and that will spank my 4 door badly but if they detune the car and it comes single turbo i doubt it will beat my awd evo since the 4gs3 can handle 400 without blueprinting and working internals.

Calm down, ladies. :rolleyes:Originally posted by Evomaniac
... but the rx-8 most probably will come with the twin turbos and that will spank my 4 door badly but if they detune the car and it comes single turbo... RX-8 = non-turbo. At least from the factory...

RX-8 1.3l n/a rotary engine and Evo7 has 2.0l turbo l4 engine. But, rotary = 2 rotors x 654cc and in piston term, rotary 1.3l equivalent to 2.6l piston engine capacity.

Evo7 will eat RX-8 in 0-60 run but it may no be the case in 1/4 mile run.
My friends and I have tested both stock RX-7 type RS vs Evo7 GSR in 1/4 mile and RX-7 (13.4) beat Evo7 (13.8) by a bumper.

The RX-8 wil STILL LOSE in a quarter mile battle w/the Evo VII. It wont make up the ground in that amount of time...but what someone said earlier is tru...perhaps in a race from like 100-160 mph...the RX8 could win...but it would be close...

Evo VII still...especially w/the variable diff control...nice stuff...not to mention the 14 inch Brembo's in the front and 12 inch Brembo's in the rear...the FMIC stock...and other nice goodies

RX8 is supposed to do the 60 in 6 seconds...

True true but this case can compared to the Skyline GTR vs Honda NSX. Skyline GTR being 2.6l turbo 4WD and NSX 3.2l n/a VTEC RWD. So definitely Evo7 will eat RX-8 in 0-60 and also 1/4 mile. But, on the other hand, i think RX-8 have high chances taking out Evo7 after 1/4 mile like running 1/2 mile or top speed.

Um, the 787B actually used a 26B engine which is actually 4 rotors, not 3.
The 20B was twin turbo, the 26B was NA peripherally ported and made 800HP.
20B = 2L, 26B = 2.6L

Actually rotary engines do not have cylinders, they have trichoidial chambers

if you need a girl to further clairify your rotary engine questions, feel free to ask...

The 787B has 4 trichoidial chambers if i'm not mistaken.

Your correct, but why dont you just call it a 4 rotor?

Back on the subject of evo vs rx8 the rx8 would be my choice most definately. the new Renesis motor has been redesigned and now has peripheral intake and exhaust ports and supposedly worked out all the bugs of the 13B's. And unlike regular motors with pistons, rotory engines don't have to make linaer motion and turn it into rotating motion. Rotory motors are all rotational motion with no loss of power. rotorys were specifically build for racing. At 1.3L naturaly aspirated it produces 250 hp at 8300rpm(I love high revers :biggrin: )The 2.0 L evo produces 270hp with turbo. To me they cannot be compared. the rx8 is also much lighter and with rwd the pull much better at top speeds. Awd systems are so heavy are hard to drift and thats no fun either. well thats my 2 cents.

y is 145-160 w/turbo good? ive done 175 in a stock s2000

y compare a car made aggressive and possibly 4 racing (EVO) with the Rx-8, made for family ppl (Rx-8) overall population?

Because both of these cars can be easily tuned for racing. The EVO is not "raced prefered" nor is the RX-8 "family prefered". Both are 4-door cars with tuned engines. Equivalent performace numbers also point out the fact that these two cars are comparable.

Realistically, the comparison should be between the WRX and EVO, but the RX-8 has some characteristics that neither the WRX or EVO has. Such as a rotary, more coupe like physque, and other stuff. In my opinion, it's the RX-8 all the way.

I am more of a bike guy myself, but needed and wanting a car for rainy days and lazy days... I decided to start looking around. It didn't take me long to come up with a short list of cars to pick from.

Today I went out and road in the RX-8 and the Evo. Both brand new and both under 25miles.

I took them on the same roads and tried to keep the same speed in some of te turns to get a good idea of how they handled as well as how they came out of the turns.

RX-8 just felt smoother. It felt like it was holding the road better even though the Evo has the AWD. Not only that but with the RX-8 I felt every bit of the road. but I didn't feel each and every pebble or any shaking in the frame. The Evo had a little shaking, a lot more body roll, and every pebble was like a knife up my back in comparison.

Now power is a different story. In the vo I couldn't find an RPM range that didn't have power. It was as if the gas pedal was a go button and that was all there was to it. There was no lag when I pressed the gas nor was there any lack of power coming out of a turn or shifting through gears. The RX-8 on the other hand made me watch my RPMs and gears more. I could easily find the power range RPMs, I just had to stay within and everything was sweet.

For me the RX-8 wins the choice in overall car by the slightest of margins, however I am looking for comfort in a car as well as power. Afterall, all these cars can be modified to get more power then we ever need. I am a corner junkie it's why I ride a bike. Not to mention neither of the cars could keep up with my bike. So speed didn't truly impress me in either of them.

Since the EvoVII was never released in america then we have to go on the Evo VIII specs. The published times are 4.9 0-60 and 13.4 for 1/4 mile. The RX-8 is rated at 5.5 and 14.5. The Evo VIII has the upper hand on speed. But the RX-8 has a PERFECT 50/50 weight ratio and it's barely slower naturally aspirated. Once Mazdaspeed comes out with a turbokit for it (and it's a for sure thing) the car will spank the rest of the market, even the new Supra waiting for 05. I love AWD, but in a lap or two around Laguna SECA I think the RX-8 would have it beaten.

THE RX7 CLUB KNOWS.......YOUR RETARDED
