oops... as per weight, i thought the z06 was 3086lbs? ive seen many 8 here at over 3100lbs.

http://www.supercars.net/cars/2391.html

not sure what the regular z06 weighs but im sure your probrably right.

i dont think the z06 is unbeatable but compared to an rx8. i jsut think dollar for dollar, $35K 2004 z06 vs $24K 2004 rx8 +9k in mods and installations, i think the z06 comes out ahead. i mean, the most 9k is gonna get you is a cheap turbo+flywheel+tyres+wheels+tuning or a high-end turbo+tuning.

however with unlimited cashflow, for the 8 to be as fast as possible, youd need:

custom turbo
new fuel system
redone exhaust ports with 3" exhaust system
standalone management
TONS of tuning
tyers
beefed up cooling system
and completely stripping out car for starters

or if you can settle with barely beating an 04 z06, you might be able to get away with

highend turbo
TONS of tunning still (350ish whp)
flywheel
tyres
and custom gearing (one of the most important factors in drag racing)

We'd be able to beat a Z06 with 350rwhp?

gh0st

with stock gearing.. no.. at least i dont think so. especially not without tyres.

you gotta remember thats whp... it equals 400+ at the crank which is what the 04 z06 puts out. now you have 2 cars same hp and weight. but the 8 has less torque so you tweak gearing. youd be supprized how how much time low hp cars can shave off 1/4 times with proper gearing.

but then again, this is all speculation and probrably will be for a long time.

hey JEOD20

i know your probrably just interested in rx8 mods but if i may make a suggestion, have you seen these cars?

http://www.arielmotor.co.uk/04/frames.htm 0-60 in 1.9 seconds for about 30k
or
http://photos.attackforums.com/showg...1&perpage=12&= in kit form it could be had for 19k or fully built for 45K

a GReddy turbo RX-8 will compete with a stock STi/EVO

talk to Hinson supercars about getting an LS1 swap

LS1 with heads and cams is good for 525 hp.

says who? GReddy?

Fanman

350 whp = almost 430 hp at the crank. I think it would be close, very close. Not to mention if you look at Mazsports 290 whp run, they got 250 tq. to the wheels. If you could get 350 whp, & almost 300 tq, you are in very good shape.

The 2003 Z06 would be about $34K, a 2004 Z06 is closer to the $37/$38 K price range (quite a bit more than $9K difference).

Again, I do think it is pretty absurd to compared a Z06 to an RX8. Two very different classes. That's like comparing a Mustang GT to a Z06. Why ? Just because GM only offers the Vette now as their only sports car ? If ultimate hp is this guys goal, I agree with a lot of the posters here that the RX8 is not a good choice. Trade your car in and get an EVO/Sti, or Mustang GT. Not better cars, just more hp. If you can't look past the engine bay, then this car won't make very much sense to you.

HardHitter

Greddy RX-8 will stay up with maybe an STI/EVO? Is that with the Interceptor-X and all of that? Most people get the STI/EVO's in order to mod them and get more HP out of them. Even if they arn't to hardcore into it, most STI's and EVO's I see are going to be somewhat modified to push more power.

Also, considering the SSR turbo kit coming out, they are saying they are close to pushing 350rwhp, who knows what those guys are doing, but if they are already pushing close to 350rwhp and then you add in the ECU like Interceptor-X, we might be looking close to a 400rwhp 8?

gh0st

very well said.

as far as sti and evos, thats 0-60 around 4.5-4.7 and 1/4 times in the low 13s. thats faster then then some 911 models and around m3 territory.

im 99% sure that with a greddy kit by itself you wont see those #. most people only see about 220-240whp which is about 280ish hp at the crank. you still have less hp, torque and mediocre 1-3 gear and useless gearing from 4th and up.

even with the interceptor x the most you will see is still 300ish at the wheels unless the turbo is moddified. but the power delivery and midrange will undoubtedly be better. then you gotta worry about getting that power to the gound because of the huge traction advantage wrx/sti's have on us. its like FANMAN said. strightline speed is not the point of this car.

I heard the mazsport is working on gearing kit for the rx-8? I would really love to have new gearings so I wouldn't have to cruise on the freeway around 3700rpm to 4k to hold the speed everyone else is going at and it would really save on gas mileage.

cretinx

Says me after spanking my buddy's EVO on the highway and having driven an STi before.

You've got to remember, our gearing especially up top is tight and the car pulls great.

cretinx

They have SICK 0-60s cuz of the AWD - the gearing up top, as I said before, isn't that great - also, look at their trap speeds - not as good as some cars that run slower 0-60s than they do. There's a reason we cruise at 4000 rpm - we're ready to accelerate even through 4th, 5th, and 6th gears.

My car is pretty much crazy on the highway

As far as traction - I have butch max performance summer 285s in the rear - I have never had a traction problem.

I also don't have most of the problems a lot of the GReddy guys complain about. No CEL, nothing weird - just lots of power all the time and a steady 7 psi.

Fanman

Doesn't work that way. They are getting about 290 whp with pretty good fuel management already. You can turn the boost up from their standard kit, and you will get extra hp. But you are assuming the Interceptor will add extra hp just because of the Greddy example. That is not the way it is going to work. The reason they can get that extra hp from the Greddy kit is because 1.) They are turning it up to a boost level not seen outside of Puerto Rico (12.5 psi), and a level where most of us said it couldn't be done on stock injectors 2.) The EManage is a marginal, at best fuel management unit.

The SSR does not have these issues. On their 280-290 whp run they already have a very good fuel management unit. You will not be able to get much more out of that (for that boost level), even if you go to a unit like the Interceptor. You will be able to turn the boost up, but the fuel tuning is pretty much as good as it is going to get. You will be lucky to get to 350 whp...period (before you should have a spare engine laying around). Also, these are limits of this engine that nobody has pushed. We have seen very few cars at near/above 300 whp. Nobody has really pushed this engine to 400 whp on a consistent basis. Nobody even knows how this engine will handle 350 whp as a daily driver, let alone 400 whp. Playing with fire here.

RX8PR

Whait for a few weeks and we would tell everyone how they work as a daily drive car with 350HP.

The blue one yesterday maked 340HP at 14 psi boost on second gear, now we're installing a second fuel pump.
The red one (mine) it's has basically the same sethings of the blue one but we still working on it, I have plans on keep it on 350HP.

My friend Ramon the owner of the blue have other plans
with he's car, probably 400HP.
Remember we have complete control of our engines for months ago, on a 32x32 base.........
We was thinking that we would like to sell our ECU system but is so custom that there is now way that we can sale it as plug and play.

Our problem is time, my mechanic has a lot of work all the time.

We would tell everyone.

How come the US is so slow in producing things on this car. It seems as if the whole world has their cars hacked and ready, yet when you come to the US with the RX8, we are just starting to figure it out lol.

Manuel, also, didn't you sell your Greddy kit? I thought I saw a post on here sometime saying you were selling it and getting something else cause it cannot produce the power you want. Did that happen, or is all of this happening on a Greddy kit, same question with the blue RX-8, which kit is he running or is it custom

twospoons_

I'm glad the puerto ricans are crazy

/twospoons

RX8PR

I sale my greddy kit 3 weeks ago........................

The blue and the red one are using GT35/40R, custom throtle, custom manifold, spearco intercooler, custom fuel rail, 850 cc injectors,etc, etc,...........
and something that you can find only in Puerto Rico

puertorican magic!
Our mechanics are the best with rotary engines......
To give you and idea on the island we have the fastest 2 rotor car on the world "Sporty racing" 7.34sec 1/4 mile.
"Major league" Rx8 body with 20B engine 6.87 sec 1/4 mile, I think Ibarra maked
6.81, he would catch it!

Do you realize that none of those "fully loaded" options made your car any faster than base 6spd RX-8?

Anyways... the most cost effective way to beat those cars is to become a better driver. In the end that is more rewarding than any mod. I suggest racing at your local auto crosses, time trials, track events... use one of the avialable instructors, and then you should be able to own any of your friends with the above mentioned cars.

Or you can forget everything that has been said here, spend $8k on a gsxr 750, put about $3k into it and smoke absolutely everything on the road. I've posted this before as a quick solution for need for speed freaks like this guy here. I love my eight, don't get me wrong, but I know the cars limit and know when to break out the bike. It amazes me how many people with those same cars try to race me when I am riding my bike. I let them hang for a second or three to boost their ego, then I just twitch the throttle and crush them. The only car to ever hang with my bike was a heavily modified 02 Cobra with a 100 shot of nitrous (was putting down around 500 rwhp). It was a 80 mph roll-on so he had somewhat of an advantage on me anyway (80 being the threshold of first gear and punching it in second would throw the front end straight up). So if you are tired of getting beat, just do what I did and be done with it.

dmorales

I agree with mmats69.

Or my solution would be:

Buy an FD for $20k and put $14k into it. Do all the work yourself, which will help you understand your car better too. Then go find a viper to smoke.

That would be Mazmart. They are said to be working on 4.1 and 3.9 ratios for the boys with big boost.

Fanman

Sounds interesting. I would be interested in a longer gearing, just so the revs in 6th would be a bit lower. I wish someone would come up with a set where 1st through 4th would be shorter & 5th & 6th a bit longer.

mike1324a

If you want a turbo that will hit hard in evo/sti territory then you have to go with the PTP motorsports turbo kit. It currently has 280rwhp and is getting an overhaul good for 300rwhp or so they say. evo has 271, mustang has 300 and sti has 300 and those are to the flywheel.
