Ok so i want to verify the information i have for my RX8 build. This winter i will be purchasing an RX8 and while its in the garage because of the snow im going to do mods and take it to an indoor track when possible.

My plans are Turbo + NO2 to achieve a total of 300-350hp. I have not yet found much info on how much the renesis can handle so any information on that would be great.

First mod will be an AP with map by MazdaManiac. After that i want to go with either an Agency or BHR mid pipe. I do not want a CEL so i was thinking the BHR with a high flow cat.

AFAIK the Agency and BHR are 3" mid pipes but what size tubing is the rest of the stock system? The reason i need to know is because my turbo will be remote mount were the stock mufflers are and i want to keep the same sized piping.

With a bigger fuel pump and injectors the AP should be able to tune the ECU to handle over 50hp of boost (correct me).

Then i will run a wet kit 55 shot or 75 shot if i can from ZEX.


So correct me on any info that is not right so i can have this all ready by december.

Thanks in advance.


EDIT: Another question i had was about the TurboXS pipe. Scince it is simply a straight pipe i know it will be loud but it flows much better. My question is if a turbo is in the path of the the TurboXS pipe then how loud will it be? Turbos make good mufflers but are they good enough to cut out the rasp and extreme high volumes of the TurboXS?

 

My opinion to you would be ALOT of searching on the different turbo kits and thier power ouput. I know your wanting to create your own remote mount setup, but they will still give you an estimate of where you want to be based on turbo sizing and whats required to get to that power goal.

I would not suggest using Nitrous and a turbo setup. It can be done and is possible, but you would be alot safer and be alot les complicated to hit your goal with only the turbo. It is totally capible to hit 300-350whp with only a turbo setup.

Using an AP for tuning may be a little harder to do now. They are no longer in production so you would have to get your hands on a used one and pay for the tuning service seperate. If you do end up getting your hands on the AP then the CEL associated with a midpipe would not be an issue. The AP can shut off the code that the midpipe would throw. - hence- no CEL. Yes, the AP would beable to controll all your tuning needs for the HP that your wanting.

Thats my little bit of information for you. Cnat really help you much on the exhaust sounds. Also, i cant stress enough the amount of surching you should do. There is ALOT if not all of this information already online here.

 

Turbo + n2o? useless.

There's a search function that will answer most, if not all, of your questions.
Indoor tracks are for go-karts...

@Phish: Aps can still be purchased through Mm's website

 

I stand corrected.

 

Indoor tracks are all i have in the winter and we have one decent one here. The most problematic thing right now is the exhaust. Since it will all have to be custom i don't want to have it sound bad.

I want no rasp with a subtle idle but a screaming top end. no drone. obviously i can't use an off the shelf cat back so i wonder if a turbo and only a turbo (the rest straight pipes) is enough to get that sound. If not i will ditch the TurboXS pipe idea and go agency power or BHR.


EDIT: i dont want to put out so much constant power that the TCS destroys my rear brakes. Hence the reason for no2

 

Learn how to drive and turn the TCS off. Problem solved. I would build the car to match the goals that i want, then worry about the sound. "form follows function"

 

You'll shoot your eye out, kid

 

I love these posts of people who don't even own an 8 yet but have all these big plans for modification. OP you have alot of research in front of you. And as already mentioned it is not recommended to both spray and turbo the 8. Your goals can be met with turbo alone. Regardless you are looking at around $5,000 to $10,000 to meet your goals. Tuning an 8 isn't like tuning a civic cost comparison wise.

 

pshhh who really needs that5 much power

 

i own a Hyundai Tiburon, similar costs to the 8 with less power. The 8 is going to sit in the garage all winter while i drive the Tiburon.

There is one problem with building it and then hoping it sounds good. I've done a lot of my research on this and know what i need.

AP to tune everything.
Turbo (unsure of type yet)
custom exhaust piping to turbo
custom intake piping to i/c
custom intake piping to tb
oil pump, tank, and lines
custom exhaust work off BOV and turbo
waste-gate set to 5psi to start.
rout air filter to fender.

thats about it. I really wasn't asking how to setup a turbo but only about the NO2, sound, and AP.

I now know what the AP can do so im good there, You guys suggest no NO2 and turbo combination, the only question left is sound. Since only one person has done this setup and they are not done yet i guess no one knows.


The turbo i have picked is the Garrett T04S. Quick spool and will easily pull of the HP i want. Not to mention it is only oil cooled which means i wont have to have water lines like a GT35R.

 

Indoor track?!?!? For a sports car???

 

well it has no walls but it has a ceiling. keeps snow off of it well during the winter.


Anyways updated plans

Garrett T04S Turbo
Custom Exhaust
Tial BOV and WG
Seperate oil system with oil cooler
2.5" Intake piping from the back to front with a small intercooler.



Set WG to 5psi with no tune till all the bugs are worked out and grab a new pump and injectors.


and that should cover my turbo setup for around 2.5k

 

X2 LMAO

 

let me start by saying, if you boost this motor without knowing exactly what you are doing, you WILL be back here crying soon about blowing it up. And blaming it on everything but your own stupid ***

ok lets see what you are asking us to verify
absolutely stupid idea. not to mention totally unnecessary.
there isnt much information about how much the Renesis can handle, least not any kind of hard concrete fact. what there is though, is dozens of turbo build threads and numerous people who have made power in the range you are talking about. You're not Lewis and Clark. This has been done and documented. Go read it for yourself, then ask questions if you have them.

Again, you havent looked into a damn thing. Firstly, a high flow cat doesnt mean you wont get a CEL. some do, some dont. Secondly, if you use an AP for tuning, you can permenantly remove the damn CEL if you wish.

Again, this information is in many places on this site alone. I won't even go into what a dumb idea that is
I certainly will. there is no such thing as 50 horsepower of boost. Boost is measured in Pounds per Square Inch(pressure) also known as PSI. Also, boost is NOT tied to how much power you make. So you cant just decide you want to run 12PSI boost because it will make XXX power. Doesnt work that way. Lastly, the ECU doesnt need to handle the boost or the power. The motor does. The ECU is not a limiting factor in any way shape or form as long as you have a way to manipulate the calibration stored in it(via the AP)

As previously stated, retarded idea. Also you obviously havent done any research into how nitrous systems work and how they apply to our cars.

[I]IF /I] you're lucky, the only thing you'll have done by December is realized the you have a good few weeks-to-months of reading and learning ahead of you

No need to thank me for informing you of how incapable you are of reaching the goals you've come up with.

This is a subjective question. anyone who answers can only be providing their opinion. Be it based on experience, or guessing. What I can tell you is that a greddy turbo kit with the TurboXS mid and catback was still loud enough to hear it idle across the parking lot.

Again, entirely subjective. Only YOU can decide whats acceptable to your ears.
You dont understand how TCS works. It's not going to destroy your brakes. Doesnt work that way.

No you havent. To put it bluntly, you dont have a ******* clue.

this isnt REMOTELY covering the things that need to be well thought out and understood to do what you want.
You should have been asking, though no one is going to spoon feed you. The turbo information is out there. The nitrous is gonna be spoonfed either, and you obviously dont understand it any better than the turbo aspect. The sound in entirely subjective. And the AP information is out there also.

the first smart thing you said. But again, even if someone had built your exact proposed setup, all the can tell you is THEIR opinion. Even a recording to listen to is fairly useless, as 99% of people dont have the equipment to properly record the full spectrum of sound, and you may not have the audio equipment to play it back properly either.

T04S doesnt tell us any specifics. There is more to turbo sizing than just the general framing. It may or may not spool quick or meet the flow you'd need. Depends on what exact turbo you get. Only oil cooled is also a stupid idea, at least in the way you said it.


You arent remotely capable of doing this yourself, or even picking out the pieces and parts yourself assuming you would have professional installation

 

Hey paul, did the pedobear touch you recently?

 

it ******* *** raped me

 

bahahha best like ever

 

wow these posts never fail to be hilarious.....seriously you need to learn the basics of cars before you try to know the advanced parts.....

but i think paul masoner put's it exactly how I would....


50HP of boost....I almost dropped my beer i laughed so hard....wow....kids will never learn....

 

I'm an ******* about it. That may often cause my opinions to be brushed aside. I'm also certainly not any high authority on this stuff. But if the OP or anyone else in similar mindset/position takes in consideration anything I said, and does their homework/verification... then hopefully one less senseless tragedy has occured, and that will only help to prevent tarnishing the image of the car, and this forum

 

yes yes and yes, even if u decide to the build or have it finsh most people who never owned a rotary wont under how much work that has to be involved so when they ask u how much u will just skip the question just no to hear the dumb remarks, of what could of should of done with your money
