i dont have it yet but am going to my an 04 manual rx8. im interested in increasing the 0-60 time but dont want to put a turbo in it. ive been researching but cant really understand all your lingo. any help is appreciated.

 

What are you having problems figuring out? Can you be more specific.

 

Take your 8 to an autocross, or get some performance driving lessons.

All the power in the world isn't going to make you faster if you as a driver do not know how to use it.

If you want 0-60 times, get a 350Z.

 

or instead of getting an AT, get a MT
that will help the 0-60 times

 

He is getting a MT read his post again

 

^^He said in the first sentence that its a manual.

 

As has been posted a billion times on this forum there aren't a lot of options for largely upgrading the power of the RX8. You won't get a large increase in performance adding the normal bolt-on performance parts. Header, cold-air intake, and exhaust will net you virtually no performance increase and depending on the brands involved can decrease performance. If you want to increase your 0-60 times and don't want a turbo then you can either go supercharger or nitrous. Some form of forced induction is required to make a noticiable difference in the power of the car. That being said, I would think long and hard about what you want out of the car before you make the jump into forced induction. Then, even if you do decide you want to make that leap, do a LOT of research before you choose which form of FI you go with. You mention that you don't want to turbo the car, but does that same dislike extend to supercharging? Do you understand the differences, benefits, and disadvantages of the two?

The biggest non-forced-induction modification you can make to upgrade the speed of the car is probably an AccessPORT with modified tuning. This can net some extra power, and greatly improve the throttle response of the car.

 

YES THAT DISLIKE DOES GO FOR THE SUPERCHARGER TOO. I DONT LIKE IT BECUASE I DONT HAVE ALOT OF MONEY AND WOULD LIKE TO SAVE SOME AND BECUASE IT SOUNDS UNRELIABLE AND COULD POSSIBLY DAMAGE MY ENGINE. by small amount of increases with bolt ons and such do you mean getting it to like 5.5, 5.3 or....... and what about a chip or tuning. i dont really know much about these other than a kid at my school has a m3 with a chip and ya........ i know that the z is more my car if i want to drag but i am in love with the rx8 style and just want it to be faster and badass it not like im actually going to drag just looking at my options.

 

Loud noises!

 

I've heard that turning your caps lock off increases your horsepower by at least 10. That could be a rumor but you might want to give it a try. You -might- be able to pick up 2-5 hp gains from assundry bolt-ons, but it will be extremely expensive compared to the gains. There are a few people on this forum who have tried a naturally aspirated path for the RX8 and only a few have broken the 200 whp mark. I already mentioned "a chip or tuning" with the AccessPORT. As far as "faster and badass" you will not get an appreciable increase over the stock car without forced induction or an engine swap. Period. Also, regardless of forced induction even, the RX8 is not a good drag car. Poor low-end torque but excellent high end and good balance mean the car is a lousy drag racer but a good track car.

 

If you don't have money to burn. Don't get an RX-8.

seriously. Good Tires on this thing cost you 700 bucks and last 1 year. It's going to get Gas mileage thats worse then a hummer and it still won't be as fast as you want.

Get the Z.

 

I smell a troll.

 

no way he's a troll. I think he's just 16 and looking for his first car.

Insurance isn't too cheap for this car either.

 

See I don't think its that bad though. I think I'm paying only 260.00 every 6 months. Now for a 16 yr old, probably way more than what I'm paying.

 

Superchargers work just fine. If you don't have a lot of money you won't be going very fast.

No. First of all those are FI numbers, you'll need 6,000 to get there. Second of all the stock RX-8 is apparently way more capable than you are, and 0-60 times have a lot to do with launch too. FI would help, but unless you know how to do it you'll never get those times.

One of the new M3s? Your car won't ever be as fast as that. Listen closely: There is nothing you can do to this car right now short of a turbo or supercharger that will make it as fast as an M3. Let's think now - the M3s put down 415ish at the crank, probably 375ish at the wheels? That and it has way more torque than you. The best, most expensive turbo kits out there for the RX-8 right now WILL get you there, but $$$$ and I don't just mean 6,000 - you'd need to look into fuel delivery, ignition, catless midpipe...it adds up fast.

You're buddy's "Chip" probably doesn't do anything to his M3. He says it gives him 50 horsepower right?


You will be disappointed if you buy this car. My best suggestion is not to buy the car - come back in a few years when we've figured this engine out better. I have no doubt we'll be seeing big numbers on it at some point.

 

how about NO2 ? It's not FI, a properly done setup $900-1000.

Go read the NO2 thread Charles Ray Hill has writen up in the Aftermarket preformance section...

Also get some HPDE classes under your belt.

Hell, here is the link.

N2o?

 

Nawwwwzzzzzassssaszqzes!

Nitrous.

Post 400 w00t!

 

Put 2 bags of cement in the boot - that will do the trick nicely .

The rest of you - READ THE QUESTION before posting your answers .

 

Wut?

 

+fatter wheels/tires

 

You're right.
Nitrogen Dioxide = NO2 NOx and forms the brown cloud

Nitrous Oxide = N2O = aka naaaaaaaazzzzzzz

I was working on a NO2 scrubber... whoops ! NO2 wouldn't work very well as a oxidizer...

 

well i havnt really done any research on any of these forced inductions but all ive heard is these can be bad for your car and can leed to breakdowns. like the sti. ive heard those are always in the shops because of there turbo.

Well you guys seem to be trying to crush my dreams. but as for going fast i think the rx8 already has a fairly 0-60 decent time (as i understand 5.8 stock.) and i know i will never be as fast as an m3 (he does claim it will give him 50 hp haha) and i dont know how much horse power gets you there but i would like to get to about 5.4 with just some bolt ons and exsuast and intake sort of things.

i will consider some forced induction. maybe nos. i will research up and then hit the post back up. hopefully you guys can steer me in the right direction but itts going to be hard for me to give up on the rx8. thanks for all the info packed responses!

 

LOL I could've sworn he said AT in his first post. I must've been tired...yeah..thats it.....

 

yea your right. im 16 and i have insurance on two cars and its comming to almost $5000
