soup up options ??
 
sup all, just testing.
hey, does anyone know if the renesis has turbo or supercharger options.. ?? or how many horses it can pump out when fully souped.. :confused: i've been lookin, but no luck

Another thing. i dont see too many bodykit options either, but i'm guessing they'll come later

N20SA22C 03-12-2003 08:20 PM

It is too early still. Their will be plenty, hopefully no stillen style kits please. They might be developing on a prototype now but come on, give them a little time. As far as how much HP, it depends on if it is a daily driver or a track car. If abel ibarra makes 800 whp with his 1.3l It should be very doable with the right amount of $$. Expect about 300 BHP(flywheel) with intake, header, exhaust, ecu. I will be doing those and have a 60-75 shot of nos to take care of pesky v8's. I have a shop that is going to prototype the MS kit when they get a chance.

performance enhancement!
 
looking for aftermarket performance enhancing goods for auto tranny.

Farsyde 03-16-2003 05:18 PM

not that the auto is bad but ugh...... If you want to feel connected to the car, get the manual. City driving doesnt suk in a manual, you just need to get used to the motions. Moral of the story, autos are for grannies....hahaha j/k.

back to the subject.....you should be able to do anything (except anything like clutch, flywheel work) to the auto you can to the manual. Exhaust, intake, body kits, guages. Keep in mind that things like engine management or ecu piggybacks can be made for the auto as well, but the demand is always sooo pour for automatic parts such as this that they may not be made.

When ya pick out the car ask yourself what you want out of it. If you want to go mod crazy, then the manual will have many more mods availible. If you just want to be different and bolt on a few aftermarket parts, then manual or auto shouldnt make a difference, except in fun factor.

N20SA22C 03-19-2003 03:34 PM

The problem you run into is no real high RPM's which is what makes a rotary fun. The torque converter can only hold so many RPM's and then it lets go. Just change your order, look at the FD rx7, the autos are worth 2-4k less in the same condition because nobody wants them.

HKS already has a turbo kit for it and Mazdaspeed is currently making a supercharger for it which may make its way over here as the Mazdaspeed version.

I want some "results".....
 
Hey people on the "top" of the world.

As you lot are getting your cars a good 6 weeks before us I'd be "really" interested in hearing your exploits regarding improving things like:
- intake
- exhaust

and any other changes like fiddling the fuel / air map with an aftermarket chip.

We only get 177kw (was supposed to be 184kw) so I'm super keen to be able to get and stay in front of the everyday Australian family cars (GMH Commodore powered by 5.7 chev).

Anyone in Japan "fiddled" their car yet?

Dyno charts obviously an advantage...

Rotar_Dude 08-08-2003 03:21 PM

performance mods?
 
hey everyone i'm supposed to be getting my 8 on monday 8/11 and was ondering what kind of performance mods can be made. Keep in mind that mine is an auto. Is there better exaust excetera.

wakeech 08-08-2003 03:24 PM

there isn't much yet, as this car is so new.

if you want to know about mods, search through the Tech Section and learn more about your car, and how power is made (if that's the kind of performance you're after).

educate yourself first, then figure out what you want to do.

btw: remember that seldom there is a universally "better" solution, and that comprimise is often the order of the day.

wakeech 08-08-2003 03:34 PM

I tried to send you a pm at first, but you aren't accepting them (hint, hint:)), and I can't send email from work, so I was stuck just removing your posts until I got home just now. We appreciate your understanding.

mods
 
If you find anywhere in the Kansas City area taht has any mods - please notify me. I am looking to make some mods myself.

Performance Mod Help
 
hi i am not a current owner of a rx-8
i actually havee a BMW 330ci hooked up...if you would like to see pictures let me know but i have about 10k in the car including performance mods

my car is a lease and when its up i am looking at a few cars
RIGHT NOW my choices are rx-8, m3, and r33 skyline gtr.

i not sure if i want the skyline becausee for a daily driver its not practical

the m3 is not completetly a tuners car

i want to get my car in the 12's in the 1/4

i like the styling of the rx-8 and would love to have 1 but as i have scanned there isnt much you can do to it
i want to know if there is or will be a turbo or sc kit coming out with a little more than 5.5 psi i am intrested in seeing close to 400 hp or close to it atleast are there gonna be any turbos or sc kits coming out within the next year or so and i also heard something about a rx-7 coming out also, is this true please inform me about this car it catches my eye alot and i would like to know more about it

mikeb 08-14-2003 01:38 AM

the rx8 will have tons of mods but its brand new and it will take time before sc, turbos, bodykits

If I was you I'd get the skyline

tpryor 08-14-2003 05:58 AM

Amen, brother. I am a VERY happy RX-8 owner, but would give it up TODAY (okay, maybe tomorrow) for a quality Skyline R34 GT-R (my personal favorite).

CMYCI 08-14-2003 10:25 AM

yes but its not practical
i get a dented fender because some jerk opened his door on my car i have to pay like $2000 to get it fixxed and order parts from japan or if it gets stuck in ahail storm
but also i like the rx-8 because its different
but like you said there will be a sc or turbo kit coming out?
and what about the rx-7 i heard?

panda 08-14-2003 10:48 AM

the rx7 is meant to be released in 2006(correct me if im wrong!), but its just a concept right now, which means that all could change.... but it would be turbo, rotary, two seats etc... again..

aftermarket for the rx8 is going to be very very good, but the car has only been out a few months max, but hopefully by january febuary time aftermarket will be starting to break through, i think the car has a lot of potential to be in the 12 second range given the right time, parts, and love :D

Mazda hasn't even committed itself to anything yet, and noone but rumour mongers said anything about a turbo.

CMYCI 08-14-2003 12:39 PM

is the mazdaspeed kit a popular kit for the rx-8
if i was to get one and put it on would i be just another 1 around that everyone has.

speakin of turbo, do you think that there will be a turbo model available?

Emsdad 08-16-2003 01:08 AM

Skylines are not "ALL that", trust me. I lived on the little island of Okinawa for a couple years. Skylines are a dime a dozen. Yes the GT-Rs are rare, but you can get better performance for the money.


I may be biased but the 8 is a better looking car by far. It's not in the same performance catagory, but for the money you'll get an incredible car.

ProtoConVert 08-16-2003 08:17 PM

For ex-Supra guys... or anyone I guess
 
What makes a BPU a BPU? Like what is the definition, and did the definition just evolve among the tuner community out of nowhere?

also, just to gratify my curiosity... what modifications were included in a BPU, and what performance increase was typical?

panda 08-17-2003 01:35 AM

bpu=basic power upgrade, bpu's are basically, i/e/h

they are available for any car im thinking but most ppl say "a supra with bpu's will beat ..........(place car here)

im pretty sure thats what bpu means, unless im thinking of a completley different thing:)



andrew

dcfc3s 08-17-2003 12:21 PM

Actually, BPU was coined by the Supra twin-turbo world. People discovered that some very reasonably priced and simple mods resulted in an astounding amount of horsepower.

On a Supra, BPU consists of a cat-back, downpipe, boost controller, and a boost cut controller of some type (to keep the ecu from cutting fuel due to higher boost). That's it. With that combo, 400-420 RWHP is EASY to obtain, and is still very solid, reliable, and easy to drive.

The twin turbo Supra is definitely a solid platform to build a LOT of power on - that engine is one strong bastard.

BTW, this is kind of off-topic...

Dale

rx7aggie 08-18-2003 11:12 PM

that basic power increase list also includes turbocharged rx-7's.

i've done the same thing, 3" exhaust, intake, FCD, and gotten some great gains from it.

SSR Engineering 08-28-2003 08:34 PM

There will be a few turbo kits out soon (Single turbo and Twin Turbo) ;)

SSR Engineering 08-28-2003 08:35 PM

Along with exhaust systems, including turbo exhaust systems (3'') and NA 2.5''

Kev 09-11-2003 01:51 AM

Combined intake and exhaust mods
 
The thing I anticipate the most are the results of the performance impact for combined intake and exhaust upgrades...

ie; gross improvement with K&N intake and a Borla exhaust, etc

I'd imagine there's potential for 20~25 rwhp gains if this is done right - but the impact on the cars everyday lower rev driving nature will be a big issue too. (You've got to live with the car!)

Any facts or theories out there on this and how it will impact or enhance the cars character?

...these are mild modifications. the impact on drivability and fuel economy should be very small, but noise on both ends will surely increase.

mikeb 09-11-2003 12:49 PM

there is really no point having one without the other.
I want headers too
there are some headers on rotaryextreme.com but no price yet

I want headers too! How the heck can you mount them without tearing the eninge out??? Hmmmm

Kev 09-11-2003 08:38 PM

Yes, I think the installation of headers would be like building a ship in a bottle.

It'll be interesting to see what headers do to the low end of the torque curve too. I want the best of both worlds, more power up top and no loss of torque down low ... with the only cost being a little induction noise and a slightly louder exhaust. (oh, I want world peace too! )

:D

colin204 09-11-2003 10:58 PM

A header should be able to be installed from the bottom no problem.

wakeech 09-11-2003 11:47 PM

yeah, noooooooo problem :rolleyes:

hahaha... :)

panda 09-12-2003 01:20 AM

yea, im guna be interested in how much the headers are for one and secondly, what kinda performance gains they will give, i am going to try to get some when the price is released, i think they should be able to be installed from underneath??

intake and exhaust will actually help your fuel economy by presenting less of a restriction.
As long as you drive the same and don't use your extra power anyways.

\

I want to know how he came to the conclusion that 20-25rwhp is waiting with an exhaust and an intake.

Oh yea, intake (15hp) and exhaust (10hp) = 25, rigght?

riiiiiight.

colin204 09-14-2003 12:53 PM

10 for intake and 10 for exhaust.

20 hp max.

I could see another 10hp for header and high flow cat.
