I haven't received my rx8 yet but from its stat it's clear to me this car is not gonna be as fast as my S2000 nor like other cars i've had before. I have decided to go w/ either a after market turbo or supercharger. At least that will push for extra 100hp.....I hope~! Are there any owners considering after market turbo for this car?
If so what are you guys considering!
S2000 was very easy to hook up, since comptech makes supercharger specially for S2k.....
need some help here, thanks.

The car is barely out in Japan and there likely won't be a super/turbo charger for some time, if at all. The engine compartment is MUCH tighter than any car you're used to have known.

JaxFL_RX8

Yeah, I've read there's no room for any kind of turbo.

Daimon

There have been many cars with tight engine compartments that can hold a turbo. Take an RSX for example or a new Celica. Their headers collect in the back of the engine which makes even less space for one. Tuners are still able to make equal length manifolds to hold a fairly large turbo.

When a turbo system is made, and it will be done by more than one company, expect to see the front half of the engine compartment to be cleared of the intake boxes, and used effectively for turbo components.

Hercules

Actually what I was getting at is the engine is so far back and low... I don't see an easy or cheap application of any forced induction.

It's not to say it won't happen... but likely for the price you're better off just waiting for the RX-7 or MPS RX-8.

RotorMotor

Oh, it'll certainly happen Herc. Mazda has said themselves on a number of occasions that the car was built with the intention of allowing people who want to add boost to add boost. I would guess that a turbo/supercharger would be out by next summer. Now, whether Mazdaspeed will come out with one that will not void your warranty is yet to be seen. I, personally, will not be adding any boost until my warranty expires unless Mazdaspeed comes out with something before then.

Regardless, there are a number of boost threads in the Aftermarket Performance forum. One of them is here:

SUPERCHARGER ALL THE WAY... SCRATCH THE TC!

MrWigggles

There is plenty of room in the engine bay. A huge percentage of the engine bay is gigantic airboxes and elongated tuned intake piping. That stuff will be gone more than likely with a turbo set-up (in-lieu of a cold air intake of some type) and an eaton-style supercharger is so small it can go about anywhere.

If they can fit turbos and superchargers in a 350Z then they can definately due it for an RX-8.

BI-STATE, a newish company offering upgraded turbos, and suspension parts for the FD is planning on having a turbo kit on the market for the 8 by the spring.

Hercules

Well don't matter to me... I'm not interested in turbos. And the lead rotary engineer doesn't want to use them either, convinced he can get the power from using wider rotors.

I'm happy with that.

RotorMotor

I'd rather go with wider rotors too, but from a practicality standpoint, I'm never going to be a world class race driver, I just want a little more speed for some fun. The multiple thousands of dollars that it would cost to build a Renesis with wider rotors doesn't make sense compared to a couple grand for a turbo kit.

Hercules

What are you talkin about?? Multiple thousands of dollars?

The new RENESIS should be in the MPS RX-8 and RX-7, and the increased horsepower as well.. it's just a matter of waiting for it. Not like I meant for you to build it yourself :p

daedelgt

I've always liked wider rotors too I'd love to see a 2 rotor 20B myself.

RotorMotor

HOLY CRAP! How much will power do you think I have? I can't wait that long!!!! :p

Otherwise known as the 13b!

dragula53

I'm assuming he meant a 2 litre displacement from a 2 rotor rotary.

not the current 20b with one less rotor.

I am pretty sure Mazdaspeed is producing a turbo charger system as we speak. I do have inside information, however I wont leak anymore

jonah428

so the bottom line.....we need to wait and see which aftermarket company can come up w/ a fantastic solution for all of us, in the meanwhile i'll just cruise my no power rx8 (but pretty), and on my fun driving day, my supercharged S2k will do the job........enjoy your 8s guys!! I will too!

(rx8 0-60 6.3 in Automotive magazine, 0-60 5.9sec in Car and Driver, I can hardly imagine any normal driver can reach 5.9 , if I think this car's slow why did i buy it? ROTARY Engine, and its uniqueness just like S2k's unique quality)

Efini 8

no power rx8? maybe if u had a honda... oh wait you do, the s2000 is an exception to the rule, however I believe the s2000 and rx8 are fairly comparable in "power" values

jonah428

I guess you haven't read what I've posted here..... ^^
it's ok, my blue 6speed fully loaded RX8 cannot even come close to my 2yr old yellow comptech supercharged S2000 w/ Mugen intake and exhaust.... Like i've posted a career racing driver can reach 60 in 6.3sec w/ rx8 and I (don't know nothing much about racing drive nor road test shxt ) can still reach 60 in 5.2 or 5.3 w/ my S2k......so when i say no power I mean it's slower than my hooked up S2k and I truly I say it again I truly wanna make my 8 faster than my S2k, that's why I'm asking people here if there're any solution for turbo/super charger.
Good Luck to all of us, and God bless all.....
hey thanks alot guys for some of you info so far....i'll keep looking too~

jonah428

I JUST HATE IT WHEN A HOOKED UP CIVIC PULLS OVER NEXT TO ME AND GIVES ME THAT LOOK! I CAN BEAT YOUR ***

MrWigggles

I guess you haven't read that the auxillary ports were stuck on some of the preproduction cars. 0-60 was tested as 5.9s by various mags and that should be what the production models do.

What mods can you do to increase the rev limit, etc... if you wanted to keep the RENESIS naturally aspriated? I mean, look at the 787B, it made a ton of power and was N/A. Granted it had twice the # of rotors, but there must be some mods you can do and stay N/A while boosting the hp.

Porting is the way to get more power... but also the way to fail inspection.
